Question

A gas is originally at a temperature of 23.13 degrees C. What temperature must it be heated to triple its volume with constant pressure?

Answer 1

Initial temperature= T1 = 23.13 °C
Initial Volume= V1 = V

Final Volume= V2 = 3V
Final temperature= T2 = ?
According to general gas eq.
                                    P1*V1/T1 = P2*V2/T2

As, the pressure is constant
 So. eq. become
                                     V1/T1 = V2/T2
                                     V/23.13 = 3V/T2                                     
                                             T2= 69.39 °C
