K.C.S.E Physics Q & A - MODEL 2000PP2QN03

a) Using the kinetic theory of gases, explain how a rise in the temperature of a gas causes a rise in the pressure of the gas if the volume is kept constant.
b) Fig. 5 shows a set up that may be used to verify Charles Law.

i) State the measurements that should be taken in the experiment.
ii) Explain how the measurements taken in (i) above, may be used to verify Charles Law.
iii) What is the purpose of the water bath.
c) A certain mass of hydrogen gas occupies a volume of 1 .6m³ at a pressure of 1.5 x10⁵ pa and temperature 12°C. Determine its volume when the temperature is 0°C at a pressure of 1.0 x 10⁵ pa.
