Question

Specific heat of a gas undergoing adiabatic change is:

• A. zero
• B. infinite
• C. positive
• D. negative

Answer 1

The correct option is A zero

For an adiabatic change, P, V and T changes. No heat exchange takes place.
$\therefore dQ=0$
$\therefore n.c.dT=0$
$\therefore$ Specific heat, c = 0
