Question

At Constant pressure a definite mass
gas is heated from O degreeC to 273 degree C, what
will be the relation between the final
initial volumes of the gas?​

Answer 1

Answer: At constant pressure the volume of a given mass of a gas increases or decreases by 1/273 of its original volume at zero degree Celsius for every 1°C increase or decrease in temperature respectively. If V' is the volume of gas at 0 degree Celsius and Vt is the volume of gas at t°C, then

Vt = V' [T/273] ; where T is the absolute temperature
