Question

One mole of an ideal gas with heat capacity at constant pressure Cp undergoes the process T= T• +alpha V where T• and alpha are constants . T is temp and V is the volume of gas . The specific heat capacity of the gas as a function of its volume is ?

Answer 1

 Demonstrate that the interval energy U of the air in a room is independent of temperature provided the outside pressure p is constant. Calculate U, if p is equal to the normal atmospheric pressure and the room's volume is equal to V = 40 m3.
