DEFINITION AND DESCRIPTION OF THE TASK The researcher will conduct an inflated balloon experiment. This experiment will allow the audience to understand clearly, "Charles' Law" and "Kinetic Molecular Theory" respectively. It will use extremely low and extremely high temperature so that the audience can evaluate the significant difference on the balloon size. The students shall be competent in presenting a laboratory experiment because it is one way to get involve in the lessons taught in school. Through experiment and actual observation of the students they can concretely say and explain the concept that "when you do this, this will occur." They will be confident enough to explain it in front of other audiences. Charles's Law states that the …show more content…
The collisions exhibited by gas particles are entirely elastic; when two molecules collide, total kinetic energy is conserved. If the temperature has increased therefore the molecules, have more kinetic energy, so they move with a more significant velocity. Methods Inflated Balloon Experiment 1.Boiling water is added to a beaker or other container. 2. The balloon is filled with air through pumping or blowing. It must not be over filled because you need to leave room for the gas inside to expand. It is best to use a party balloon instead of a water balloon. It decreases the chance that the balloon will pop. 3. A string is wrapped around the widest part of the balloon. By wrapping a piece of string around the balloon, you can get an accurate measurement of how big the balloon is in the beginning. Either mark or cut the string at the broadest part of the balloon. The string is removed from the balloon and measured by a ruler. This measurement is the first circumference of your balloon. You will want to compare this to the size of the balloon once the air inside heats
First the ball had a small hole directly in the center and the rod had an uneven end these presented challenges for getting an accurate measurement in step III. Second the errors in the measurements were carried through and expanded by the calculations performed. The obtaining the volume via the displacement method was only one step without calculations. Thus I believe the displacement method produce better measurments. 4.

How does temperature affect the bounce of a tennis ball My science fair project is about tennis balls and temperature. I chose this topic because I am interested in how temperature affects how high a tennis ball bounces. When the ball hits the floor it expands and when it comes up then it comes back up it contrasts. My question that is going to be answered is,how does temperature affect the bounce of a tennis ball?
Introduction Alka-Seltzer has been on the market since 1931 and has helped to relieve indigestion and upset stomach. The tablets began to fizz and bubble when dropped into water. “The fizziness happens when baking soda (sodium bicarbonate) and citric acid react chemically in water. They yield sodium citrate, water and carbon dioxide gas, which causes bubbles.” Based on this information, we will measure the reaction time of AlKa- Seltzer dissolved in 200 ml of water at 3 different tempertures in the first portion of this experiment.
Red Bead Experiment Submitted By: Sarabjeet Singh (C0712487) Arshdeep Singh (C0719013) Harshpreet Singh (C0713155) Lovish (C0717943) Introduction Red and white beads experiment explained in video mainly based on the Integrated Environment, Safety and Health Management System, it includes all the all the core functions of ISMS environmental management aspects in all five core management functions that support work planning or work scope, hazard analysis, hazard control, work performance, and feedback and improvement. The instructor of the Red Bead experiment, Dr. Deming started with the definition of the work scope, the scope definition serves the purpose of stating exactly what it is that an organization does that is certified to be effectively controlled by the requirements of the standard. Dr. Deming gave different examples by the red and white beads.
The Little Albert experiment was a case study showing empirical evidence of classical conditioning in humans. The study also provides an example of stimulus generalization. It was carried out by John B. Watson and his graduate student, Rosalie Rayner, at Johns Hopkins University. The results were first published in the February 1920 issue of the Journal of Experimental Psychology. After observing children in the field, Watson hypothesized that the fearful response of children to loud noises is an innate unconditioned response.
Introduction The intent of this experiment is to understand how hot and cold water interact with each other by combining clear hot water and black ice cold water. I hope to learn more about how hot and cold water interact with each other. As of now, I know that cold water is denser than hot water. Knowing this I formed my hypothesis.
In conclusion, air pressure has a direct influence on the distance that the ball will travel when thrown. The hypothesis stated that if pressure is added to the football, then the distance the ball projects will increase when distance is a function of pressure. Based on the data that was collected from the experiment, the hypothesis was supported. When the football had more air inside, it went the farthest distance compared to the other two pressures that data was collected from.
Then the scientist will observe the different rates of reaction with temperature. The Boltzmann distribution of law, indicates that high temperature makes molecules gain high energy contents (pubs.acs.org/doi/abs/10.1021/ja). In order to measure the reaction rate, the scientists must use the same volume of water at three different starting temperatures: hot tap
My project is about how temperature and air pressure affect the distance a football can be thrown. When the air is warmer the molecules move faster and spread apart, therefore making the air pressure lower and making the ball lighter. But when the air is cooler the molecules move slower and move closer together, making the air pressure higher making the ball
Title: THE BALLOON INFLATION REACTION Introduction: Chemistry is one thing that makes us understand and gives us reasons of why certain reactions gives certain results. In this experiment we will be illustrating the reaction between baking powder and vinegar and see what happens to the balloon that is attached to it. Hypothetically the reaction of the vinegar and baking powder will produce carbon dioxide which will inflate the balloon. If the more vinegar may happen that when more vinegar is added to the baking powder it may produce more carbon dioxide thus the balloons diameter increases.
Self-discovery is driven by the willingness of individuals to make connections with places and people. This is evident in Tara June Winch 's novel "Swallow the Air" as the protagonist discoveries are seen through her connection with the people and her identity. Similarly, the same can be said for James Cameron 's film "Avatar" as Jake the protagonist discoveries is 'visualised through his connection with the land and how this affects his identity. In both of these texts, we can identify how both Tara June Winch and James Cameron interprets the concept of self-discovery in their text.
Place the the beaker onto a hot plate that is on a low heat setting (about setting 3). Every 5 minutes for 20 minutes, measure the circumference of the balloon and record it in Data Table A. You can measure the circumference of the balloon by looping a piece of string around it then using a ruler to measure the string’s length. Record the data in the data
DESIGN PSOW Ajit Rajendran 13H To Determine the Time Taken for a muffin paper cup to reach the ground, while Changing the Height of each experiment Introduction: In this experiment the aim is to determine the time taken for an empty muffin paper cup to reach the ground, by changing the height the empty cup is dropped from. Both variable mentioned are going to measured (height and time taken), when conducting the experiment. In order to have a fair experiment, certain factors will be kept the same throughout the experiment: the same paper cup will be used, the dimensions of the paper cup will be constant (where external factors do not affect the shape), the method in which the paper cup will be dropped.
This means there might be slight variation in the temperature of the substances used for the experiment. Temperature affects the rate of collision by adding or lessening the amount of kinaesthetic energy for particle collision. Thereby affecting the rate of reaction. Wait for substance to adjust to room temperature before use. Container, the container affects the surface area and the number of particles that are exposed to each other
