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.

  • AStatement $1$ is true, Statement $2$ is true,

    Statement $2$ is a correct explanation of Statement $1.$

  • BStatement $1$ is true, Statement $2$ is false.
  • CStatement $1$ is false, Statement $2$ is true.
  • DStatement $1$ is false, Statement $2$ is true,

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