Hi Shrushti,

If you go by the ideal gas equation ie; pV=nRT where the Temperature(T) is considered in Kelvin. If you consider T=0 then all the quantities ie; pressure volume mass will be equal to 0.

There can be the derivation of formulas from the ideal gas equation but all will result in the same

Hello Shrushti ,

According to Kinetic theory of gases ,mass of an ideal gas can never be zero and internal energy would too never turn to be zero ,so at constant pressure ,the volume would be zero .Hope this information is helpful and please do ask more queries if needed.Thank you .
