Q. Absolute zero temperature is not the temperature of zero energy why?

Q. At absolute zero, gases lose their characteristic properties. Which of the following sequence of explanation is correct for justifying the above fact?
(a) The value of zero for volume coordinate shows that gases occupy no volume
(b) Volume occupied by a gas decreases with a decrease in temperature
(c) At

- {273.15}^{o}

C (absolute zero), the plot of V vs

t^{0}

C intersects the temperature axis
(d) A gas occupying zero volume means that the matter does not exist in the gaseous state

Q. Assertion :The lowest hypothetical or imaginary temperature at which gases are supposed to occupy zero volume is called absolute zero. Reason: Volume of the gas at

- {273.15}^{\circ} C

becomes zero i.e. gas does not exist at this temperature.

Q. At absolute zero temperature:

Q. Assertion :At absolute zero temperature, vapour pressure, kinetic energy, and heat content of the gas reduce to zero. Reason: At absolute zero, temperature velocity reduces to zero.
