Density Of Balloon Essay

762 Words4 Pages

DENSITY is a physical property of matter, as each element and compound has a unique density connected with it. Density defined in a qualitative manner as the measure of the relative "heaviness" of objects with a constant volume. For gases the density may amount with the number of gas molecules in a constant volume.

Helium balloon: Compare the behavior of helium filled balloon with that of an air filled balloon. Even taking into account the weight of the rubber balloon, the helium balloon floats on the air and is less dense than the air. The air filled balloon sinks because the weight of the rubber balloon makes is a bit heavier and far denser. Hydrogen balloon: Compare the densities of hydrogen, helium, and air to estimate what will happen to a hydrogen balloon. In the hydrogen balloon demonstration usually not enough hydrogen fills the balloon to conquer the weight of the balloon. Sometimes you can almost see …show more content…

As air is heated, it becomes less dense than the surrounding cooler air. The less dense hot air has enough lifting power to cause the balloon to float and rise into the air.
• Cold Water Vapor: What causes a cloud to sink to the earth surface and we call it fog. Tiny droplets of water are present in clouds and fog. If the surrounding warm air is cooled it sinks since it is denser, and at the same time the water as a gas is condensed into tiny droplets of water.
Application: Liquid Nitrogen Demonstration the white fog coming from the liquid nitrogen container is having the same effect as described above.

Mathematical Definition of Density
The formal definition of density is mass per unit volume. Usually the density is expressed in grams per mL or cc. Mathematically a "per" statement is translated as a division. cc is a cubic centimeter and is equal to a mL Therefore, Density = Mass = g/mL Volume

Demonstrations with Density

  • Chapter 5 Summary Of Buoyancy

    267 Words  | 2 Pages

    In chapter five, Pink discusses the trait of “buoyancy,” or what he defines as the ability to stay afloat when waves of rejection and adversity strike. According to Pink, buoyancy is composed of three different components: interrogative self-talk, positivity ratios, and explanatory self-talk. In the first component, Pink suggests that instead of only using positive self-talk whenever we are planning to move someone, we use interrogative self-talk. This is because asking ourselves questions, such as “Can I do this?” will elicit reasons for doing something, create room for improvement, and produce better results.

    In this week’s lab we had to determine the density of a quarter, penny, and dime. My question was “How does is each coin?” Density is the amount of mass in an object. To find the density of each coin in this lab, we used a triple beam balance to find each coin’s mass and a graduated cylinder to find their volumes. With all this information, I can now form a hypothesis.

    The Pop Rocks have a very small amount of carbon dioxide in them. When the Pop Rocks are in your mouth they dissolve and the carbon dioxide is released making the pieces of candy explode in your mouth. When the Pop Rocks come in contact with the soda, the gas in the Pop Rocks escape after disolving and the carbon dioxide escapes from the liquid into the balloon. When this happens it causes the gas to make the balloon expand bigger and bigger until the air can escape.

    Also, the pictures above show how the egg changed from being tight and solid to being flexible. The observations also say that the egg felt like a water balloon and was full of water inside. Overall, the egg greatly shrunk in size. Finally, when the egg was placed in corn syrup, it floated on the surface of the solution. This was because the egg floated in solutions hypertonic to its inside.

    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.

    The heart may have the sinoatrial node (SA node) to trigger contraction, but in order for us to breath our nervous system has to signal for us to begin the process of ventilation (breathing). Our brain stem has three parts to it, but only the pons and medulla oblongata play a key role in breathing. The medulla helps set the respiratory rhythm by receiving and sending impulses to a bundle of neurons called the ventral respiratory group to the phrenic nerve to bring about contraction in the diaphragm and external intercostal muscles. All this only happens though due to the sensors of the chemoreceptors. The chemoreceptors located in the medulla and carotid and aortic bodies detect a rise in carbon dioxide (CO2).

  • Probability Distribution Case Study

    We can view a probability distribution in two ways. The basic view is the Probability function, which specifies the probability that the random variable takes on a specific value: P(X=x) is the probability that a random variable X takes on a specific value x. (Note that capital X represents the random variable and lowercase x represents a specific value that the random variable may take). For a discrete random variable, the shorthand notation for the probability function is p(x) = P (X=x). For continuous random variables, the probability function is denoted f(x) and called the probability density function.
