MCQ

This question has Statement $1$ and Statement $2.$ Of the four choices given after the Statements, choose the one that best describes the two Statements.
Statement $1:$ In an adiabatic process, change in internal energy of a gas is equal to work done on/by the gas in the process.

Statement $2 :$ The temperature of a gas remains constant in an adiabatic process.

A
Statement $1$ is true, Statement $2$ is true,

Statement $2$ is a correct explanation of Statement $1.$
✓
Statement $1$ is true, Statement $2$ is false.
C
Statement $1$ is false, Statement $2$ is true.
D
Statement $1$ is false, Statement $2$ is true,

Statement $2$ is not a correct explanation of Statement $1.$

✓

Answer

Correct option: B.

Statement $1$ is true, Statement $2$ is false.

b
In an adiabatic process, $\delta H = 0$ And according to first law of thermodynamics

$\delta H= \delta U+ W$
$\therefore W=-\delta U$
