For an engine at 0K what happens?

When the temperature of a gas filled in a closed vessel is increased by 1^o C, its pressure increases by 0.4 %.  The initial temperature of the gas was

At which of the following temperature would the molecules of gas have twice the average kinetic energy they have at 20⁰C?

Let the Volume-temperature graph at atmospheric pressure for a monoatomic gas (V in m³, T in ⁰C) is:

A container has N molecules at absolute temperature T.  If the number of molecules is doubled but kinetic energy in the box remains the same, the absolute temperature of the gas is

What is the absolute mass of an atom of oxygen?  Atomic mass of oxygen is 16 and Avogadro's number =

The Graph of specific heat at constant volume for a monoatomic gas is :

The ratio of the speed of sound in nitrogen gas to that in helium gas, at 300 K is:

If an ideal gas has volume V at 27⁰C and it is heated at a constant pressure, so that its volume becomes 1.5 V, then the value of final temperature is:

The relation between pressure P and average kinetic energy E per unit volume of a gas is:
