Question

INTRODUCTION PART 1 when they collide Gases are made up of molecules that are in constant motion and exert pressure molecules with the walls of their container. The velocity and the number of collisions of these you will are affected when the temperature of the gas increases or decreases. In this experiment, You study the relationship between the temperature of a gas sample and the pressure it exerts. will place an Erlenmeyer flask containing a trapped air sample in water baths of varying temperature. Pressure will be monitored with a Pressure Sensor and temperature will be monitored using a Temperature Probe. The volume of the gas sample and the number of molecules it contains will be kept constant. Pressure and temperature data pairs will be collected during the experiment and then analyzed. From the data and graph, you will determine what kind of mathematical relationship exists between the pressure and absolute temperature of a confined gas and use your data to find a value for absolute zero on the Celsius temperature scale. This gas law is known as

Explanation / Answer

Gay-Lussac's Law, Amontons' Law or the Pressure Law, was found by Gay-Lussac.It states that, for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.

P is directly proportional to T

P = K T

where P is the pressure, T is the absolute temperature, and k is another proportionality constant.

This law also can be written as

P/T = K

or

P1/T1 = P2/T2

Since P and T possess direct relationship, as temparature doubled P also got doubled.
