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

Air is pumped into an automobile tube upto a pressure of 200 kPa in the morning when the air temperature is 22$^ \circ C$. During the day, temperature rises to 42$^ \circ C$ and the tube expands by 2%. The pressure of the air in the tube at this temperature, will be approximately

A beaker is completely filled with water at ${4^0}C$. It will overflow

The volume of a gas at ${20^0}C$ is 100 CC at normal pressure when it is heated to ${100^0}C$, its volume is 125 CC at the same pressure the volume coefficient of the gas is

The volume of a gas at ${20^0}C\,is\,100c{m^3}$ at normal pressure. If it is heated to ${100^0}C$ its volume becomes $125c{m^{^3}}$ at the same pressure, then volume coefficient of the gas at normal pressure is

The coefficient of real expansion of mercury is $0.18 imes {10^{ - 3}}^0{C^{ - 1}}$. If the density of mercury at $^0C$ is 13.6 g/cc, its density at 473 K will be

The gas thermometers are more sensitive than liquid thermometers because
