In a given process on an ideal gas dW = 0 and `dQ angle 0.` Then for the gas :

Options

A. the volume will increase
B. the temperature will increase
C. the pressure will remain constant
D. the temperature will decrease.

Answer

A

Explanation

As `dQ lt 0 and dW=0`
`& dQ =dU+dW`
change in internal energy `dU lt 0`
`rArr` Internal energy decreases and hence temperature also decreases.
Thus, correct choice is (a).
