Question

h

Answer 1

Charles’s law states that if a given quantity of gas is held at a constant pressure, its volume is directly proportional to the absolute temperature.

the assumptions are:
1. Gases are made up of molecules which are relatively far apart.
2. The molecules are in motion at high speeds.
3. The molecules are perfectly elastic.
4. Increase in temperature increases the kinetic energy of the molecules.

Vi/Ti = Vf/Tf

where
Vi = initial volume
Ti = initial absolute temperature
Vf = final volume
Tf = final absolute temperature

Charles's law is used to calculate the volume the gas will occupy if the temperature is increased to 170 C while the pressure is held constant.
