# NEET Physics Thermodynamics Questions Solved

In a given process for an ideal gas, dW = 0 and dQ < 0. Then for the gas -

(1) The temperature will decrease

(2) The volume will increase

(3) The pressure will remain constant

(4) The temperature will increase

(1) From FLOT

$dU=dQ-dW⇒dU=dQ\left(<0\right)$    $\left(\because \text{\hspace{0.17em}\hspace{0.17em}}dW=0\right)$

$⇒dU<0$ So temperature will decrease.
