In an adiabatic expansion of an ideal gas the product of pressure and volume

Question

In an adiabatic expansion of an ideal gas the product of pressure and volume (A) Decreases (B) Increases (C) Remains constant (D) At first increases and then decreases

Tardigrade Admin · Accepted Answer

In an adiabatic expansion as temperature decreases from an ideal gas equation PV=nRT. Product of pressure and volume also decreases.

Q. In an adiabatic expansion of an ideal gas the product of pressure and volume

Decreases

Increases

Remains constant

At first increases and then decreases

In an adiabatic expansion as temperature decreases from an ideal gas equation $P V = n RT$ .
Product of pressure and volume also decreases.
