The PV diagram for three different isothermal processes A, B and C are shown above. Chose the correct option.

Which of the following is isentropic process

The point marked in the diagram represents the state of a fixed quantity of ideal gas in a container with a moveable piston. The temperature of the gas in the state shown is $600\mathrm{K}$. Copy the diagram. Indicate on the diagram the point representing separate change.

a. The volume doubles at a constant temperature.

The graph for Boyle's law is called

Represent the union of two sets by Venn diagram for each of the following.

$X=\{x | x$ is a prime number between $80$ and $100\}$

$Y=\{y | y$ is an odd number between $90$ and $100\}$

The figure shows two isotherms at temperatures $T_1$ and $T_2$. A gas is taken from one isotherm to another isotherm through different processes. Then change in internal energy $\Delta \text{U}$ has a relation –

If the indicator diagram for expansion of gas is as shown, the gas

Two isothermals are shown in figure at temperature $T_1$ and $T_2$. Which of the following relations is correct?
