A diatomic gas molecule has

While deriving the equation for pressure of a gas we consider the

Absolute zero is considered as that temperature at which:

Two metal rods A and B have their initial lengths in the ratio 2 : 3 and coefficients of linear expansion in the ratio 4 : 3. When they are heated through same temperature difference the ratio of their linear expansion is

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

The relationship between Boltzmann constant k with R and NAis given as:

First law of thermodynamics is consequence of conservation of

The ideal gas law is

On the power stroke, a spark fires the mixtures causing a rapid increase in pressure and temperature and the burning mixture expands

Truth of kinetic energy is confirmed by:

The work done by the system on its environment is considered as

Real gases strictly obey gas law at:

The earliest heat engine was

On colliding in a closed container, the gas molecules

The example of reversible process is

The behaviour of gases is well accounted by the kinetic theory based on

Specific heat at constant pressure is greater than the specific heat at constant volume because
