Is it possible to increase the temperature of a gas without adding heat to it? Explain.

<p><span data-teams="true">This is a short answer type question as classified in NCERT Exemplar</span></p><p>Yes during adiabatic compression the temperature of a gas increases while no heat is</p><p>In adiabatic compression dQ=0</p><p>From the first law of thermodynamics dU= dQ-dW</p><p>dU=-dW</p><p>in compression work is done on the gas i.e work done is negative</p><p>dU=positive</p><p>hence internal energy of the gas increases due to which its temperature increases.</p>
