The product of the pressure and volume of an ideal gas is

Assertion : For an ideal gas, at constant temperature, the product of the pressure and volume is constant. Reason : The mean square velocity of the molecules is inversely proportional to mass.

Write adiabatic relation between pressure and volume of an ideal gas.

Write the isothermal relation between pressure and volume of an ideal gas.

(A): For an ideal gas, at constant temperature, the product of the pressure and volume is a constant. (R): The mean square velocity of the molecules is inversely proportional to mass.

The pressure p and volume V of an ideal gas both increase in a process.
