The volume occupied by 8gm of oxygen at S.T.P is

What is the mass of 2 L of nitrogen at 22.4 atm pressure and 273 K?

In the relation $n = \frac{{PV}}{{RT}},n =$

When the pressure on water is increased the boiling temperature of water as compared to ${100^0}C$ will be

A real gas can be approximated to an ideal gas at

A metal rod of length $L$ at temperature $T_1$ is heated to a temperature $T_2$. The coefficient of linear expansion of the metal is $\alpha$. The rod is then constrained from expanding lengthwise. What is the thermal stress developed in the rod?

Saturated vapour is compressed to half is volume without any change in temperature, then the pressure will be

Ice, water and steam co-exist at triple point temperature 273.16K and pressure 4.6mm Hg. In a system in which the triple point conditions of temperature and pressure exist, the pressure is increased a little while keeping the temperature constant, then the system contains

One gram of ice is mixed with one gram of steam. At thermal equilibrium the temperature of mixture is

Saturated vapour is compressed to half is volume without any change in temperature, then the pressure will be

On heating, the temperature at which water has minimum volume is
