1.	In an adiabatic expansion the product of pressure and volume :A. decreasesB. increasesC. remains constantD. first increases then decreases.
Answer» Correct Answer - A In an adiabatic expansion, internal decreases and hence temperature decreases. `:.` from equation of state of ideal gas PV=nRT `rArr ` the product of P and V decreases
