Which of the following is a FALSE statement?
The difference in entropy between two states of a system is independent of the path between the two states.
Entropy is a quantitative measure of disorder.
The total entropy change in one cycle of a Carnot engine is zero.
The entropy of an isolated system can decrease.
In an adiabatic expansion of a gas initial and final temperatures are ${T_1}$ and ${T_2}$ respectively, then the change in internal energy of the gas is
If coefficient of performance of a refrigarator is $\beta $ and heat absorbed from refrigarated space is $Q$, then work done on the system is
In the following indicator diagram, the net amount of work done will be
A monoatomic gas $(\gamma = 5/3)$ is suddenly compressed to $\frac{1}{8}$ of its original volume adiabatically, then the pressure of the gas will change to
If $R =$ universal gas constant, the amount of heat needed to raise the temperature of $2 \,mol$ of an ideal monatomic gas from $273\, K$ to $373\, K$ when no work is done is-
