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.
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.
Statement $1$ is false, Statement $2$ is true.
Statement $1$ is false, Statement $2$ is true,
Statement $2$ is not a correct explanation of Statement $1.$
Solution
In an adiabatic process, $\delta H = 0$ And according to first law of thermodynamics
$\delta H= \delta U+ W$
$\therefore W=-\delta U$
