Can we increase the temperature of a gas without supplying heat to it?

Text Solution

Verified by Experts

Yes, This happens when the gas undergoes, adiabatic compression.
From `dQ=dU+dW`
as `dQ=0` in an adiabatic process,
`:. dU+dW=0` or `dU= -dW`
In compression, work is done on the gas, therefore, `dW` is negative. Hence, `dU is +, i.e., internal energy of the gas increases. Hence, temperature of gas increases.
