The Mathematical Relationship Between Pressure And Volume
The mathematical relationship that exists between pressure and volume when temperature and quantity are held constant is that pressure is inversely proportional to volume. This relationship is known as Boyle’s Law. P1 x V1 = P2 x V2. When the volume of a container is decreased, when still containing the same amount of molecules, more molecules will hit the sides of the container, thus increasing the pressure.
We were asked to graph pressure and the inverse of volume because the graph of pressure and inverse volume is inversely related to the graph of pressure and volume. The graph allows a visual representation of what being inversely related conveys.
The mathematical relationship that exists between volume and temperature when pressure and quantity are held constant is that volume is directly proportional to temperature. This relationship is known as Charles 's Law. (V1 / T1) = (V2 / T2). This relationship can be observed within a balloon placed within ice water and boiling water. Within the boiling water, the molecules within the balloon are moving faster, revealing high kinetic energy and a larger volume than the molecules within the balloon of the ice water.
The line of best fit reveals the y-intercept temperature as -10.61 K. This temperature represents when volume is also equal to zero. Absolute zero is when temperature is 0 K, leading to pressure and volume to also equal zero. The calculated number is slightly off from the actual, accepted value for absolute

1232 Words | 5 PagesThe temperature probe was then quickly cooled to room temperature. When this was achieved, the hot water was immediately transferred into the calorimeter. This method of keeping the temperature probe cooled before measuring a new temperature was repeated throughout the entire experiment. Temperature data was collected for 180 s while swirling the temperature inside the calorimeter. The calorimeter still contained the warm water.
Explain Why Did The Alaskan Way Viaduct Collapse
464 Words | 2 PagesWhen atoms are cold they sink because they are more compacted and don’t move around as much. Sink or Float was a lab that showed about temperature and density changes. With the cold water we saw it sink and just stay at the bottom of the container without moving. When the hot water was added it made it rise to the top of the container and spread. That showed us that the bottom layers would be hotter and the top layers would be colder.

The Effect Of Temperature On The Bounce Of A Tennis Ball
316 Words | 2 PagesHow 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?
Boiling Point In Intermolecular Science
1053 Words | 5 PagesA boiling point of a substance is dependent on the temperature at which the substance can change its matter, such as liquid to gas. The molecules present in liquid are tightly compressed together, though they are still moving and colliding. If the liquid is heated, there is a rise in temperature which generates vibrations throughout the liquid, resulting in more collisions between molecules (Helmenstine, 2017). Once the collisions between the molecules become quite intense and rapid, boiling starts to take place. There are molecules that are so powerful, they break through the attraction forces that keep the molecules together, this is called intermolecular forces (Ophardt, 2013).
Cold Water Lab
630 Words | 3 PagesIntroduction 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.
Lab Report Scaffold: Bromination Of Trans-Cinnamic Acid
904 Words | 4 PagesChem 51 LB Experiment 3 Report Scaffold: Bromination of Trans-Cinnamic Acid 1. The goal of this experiment was to perform a halogenation reaction through the addition of two bromides from pyridinium tribromide. This was accomplished by reacting trans-cinnamic acid with pyridinium tribromide. After the reaction took place, melting point analysis was conducted to find out the stereochemistry of the product, which could either be syn-addition, anti-addition, or syn + anti-addition. 2.
Essay On The Effect Of Temperature On Osmosis
1159 Words | 5 PagesWhen temperature is increased, the amount of obtainable energy increases; meaning that particles will move at faster pace at a higher temperature. Thus rate at which molecules diffuse will progressively speed up as the temperature increases. However if temperature of solution is decreased the rate of osmosis will decrease and rate at which molecules diffuse will be significantly less than that of higher
How Fast Does Alka Seltzer Make Gas
621 Words | 3 PagesThen 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

976 Words | 4 PagesThe mass of an 11 dram vial was taken before and after it was filled with 15 mL of distilled water, resulting in a mass of 29.9667 grams without the distilled water and 44.7771 grams with the distilled water. The looped wire was inserted into the 11 dram vial, to be used for stirring. The 11 dram vial was then submerged into the ice bath, and the Vernier temperature probe was immersed into the 11 dram vial. Once the temperature of the distilled water reached 10°C, the temperature was recorded every 10 seconds. After the data was collected, the 11 dram vial was brought back to room temperature.
How Does The Amount Of Baking Soda Mixed With Vinegar Affect The Volume Of Gas Produced?
1211 Words | 5 PagesI predict that the more baking powder added to the vinegar, the more reaction will take place causing for more gas to be produced per 10 seconds. There will be a gradual decrease in difference between volume in gas per 10 seconds over the duration of time. I predict that the more baking powder is added, the more gas will be produced because there is more vinegar to react with baking powder The chemical name for baking powder is sodium bicarbonate (NaHCO3) and vinegar is acetic acid
Temperature In Footballs
63 Words | 1 PagesMy 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
