Gasses have various properties that can be observed by our senses. The gas pressure, temperature, mass and volume are variables that are related to one another. here is an activity to understand the relationship of Volume V and Temperature T of a gas confined at constant Pressure. The no. of moles or amount of gas is constant. The syringe contains fixed no. of moles of a gas at constant pressure. It is air tight fixed to a pressure gauge and a digital thermometer. When the glider is moved the temperature of the gas in syringe changes. Observe the change in the volume of the gas. Record and display Volume and Temperature readings in a table. In 1787 Jacques Charles studied the relationship between volume and temperature of gas. The volume of a fixed amount of gas at constant pressure is directly proportional to its Kelvin temperature. This relationship is called Charles' Law in his honour. Consider an inflated balloon. When liquid nitrogen is poured on its surface, it cools the balloon and its contents to a temperature far below room temperature and the balloon collapses. As the balloon warms up to room temperature it reinflates as the air in the regains the volume it had at room temperature.
