A

`(r.pV)/(gamma-1)`

B

`r/(gamma-1)`

C

pV

D

`(pV)/(gamma-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`Delta U=nC_(v)dT=n(R/(gamma-1)) DeltaT=(PDeltaV)/(gamma-1)=(PV)/(gamma-1)`

One cubic metre of an ideal gas is at a pressure of 10^5 N//m^2 and temperature 300K. The gas is allowed to expand at constant pressure to twice its volume by supplying heat. If the change in internal energy in this process is 10^4 J, then the heat supplied is

For an ideal gas a) The change in internal energy in a constant pressure process from temperature T_(1) to T_(2) is equal to nC_(v) (T‌_(2)-T_(1)) , where Cv is the molar heat capacity at constant volume and n is the number of moles of the gas b) The change in internal energy of the gas and the work done by the gas are equal in magnitude in an adiabatic process c) The internal energy does not change in an isothermal process d) No heat is added or removed in an adiabatic process
