Question
When an ideal gas undergoes an adiabatic change causing a temperature change ᐃT
(i) there is no heat gained or lost by the gas
(ii) the work done by the gas is equal to change in internal energy
(iii) the change in internal energy per mole of the gas is Cv ᐃT, where Cv is the molar heat capacity at constant volume.
(i) there is no heat gained or lost by the gas
(ii) the work done by the gas is equal to change in internal energy
(iii) the change in internal energy per mole of the gas is Cv ᐃT, where Cv is the molar heat capacity at constant volume.
Options
A.(i), (ii), (iii) correct
B.(i), (ii) correct
C.(i), (iii) correct
D.(i) correct
Solution
Adiabatic process
ᐃQ = 0
For any process
ᐃU = nCVᐃT
Hence, option (C) is correct.
ᐃQ = 0
For any process
ᐃU = nCVᐃT
Hence, option (C) is correct.
