Hint:Absolute temperature is also called thermodynamic temperature. Absolute temperature means absolute zero. Temperature of a substance at absolute zero is zero Kelvin or $- {273^ \circ }C$. At this temperature energy of the thermodynamic system is the lowest.
Absolute temperature is also called thermodynamic temperature. At this temperature thermodynamic energy of a system is lowest. Absolute temperature is equal to zero Kelvin or $- {273^ \circ }C$ which is also called absolute zero. At absolute zero temperature the motion of the gas particles is ceased. This means there is no motion between the particles of the gas. The volume of the gas is zero at absolute temperature. Therefore absolute zero of a gas is the measure of volume of gas.
Additional information: According to the ideal gas equation, $PV = nRT$. Where, $P$ is pressure, $V$ is volume, $n$ is number of moles, $R$ is gas constant and $T$ is temperature. From this equation we can observe that the number of moles of gas depends on temperature, pressure and volume of the gas but the number of particles in one mole of a substance is constant. There are Avogadro numbers of particles in one mole of substance. Avogadro number is equal to $6.022 \times {10^{23}}$.
