Question

A cyclic process on an ideal monatomic gas is shown figure. The correct statement is

• A. work done by gas in process AB is more than that in the process BC
• B. Net heat energy has been supplied to the system
• C. Temperature of the gas is maximum at state B
• D. In process CA heat energy is absorbed bu system

Answer 1

The correct option is B Net heat energy has been supplied to the system

For cyclic process

$\Delta u=0$

In this process

$\Delta w=(+)$

$\therefore \Delta Q=\Delta u+\Delta w=(+)$

Net heat energy is absorbed by system$.$

Hence,

option $\left(B\right)$ is correct answer.
