Find For an ideal gas:
A
The change in internal energy in a constant pressure process from temperature 
to 
is equal to n 
, 
, where 
, is the molar specific heat at constant volume and 
the number of moles of the gas.
to is equal to n , , where , is the molar specific heat at constant volume and 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.
A, B, C
A, B, C
C
The internal energy does not change in an isothermal process.
D
No heat is added or removed in an adiabatic process.
Which of the combination are correct? A, C
Which of the combination are correct? A, C
Text Solution
Verified by ExpertsThe correct answer is:
C
Change in internal energy depends only on change in temperature since internal energy is a function of state only i.e., 
.
In adiabatic process, 
,
Hence, 
i.e., magnitude of change in internal energy is equal to magnitude of work done.
