Does an ideal gas exist in reality?

For an ideal gas,

When the temperature of an ideal gas is increased by 600 K, the velocity of sound in the gas becomes sqrt 3 times the initial velocity in it. The initial temperature of the gas is

What is an ideal gas?

For n moles of an ideal gas, the ideal equation may be written as "_____________" .

One mole of an ideal gas at an initial temperature true of TK does 6R joule of work adiabatically. If the ratio of specific heats of this gas at constant pressure and at constant volume is 5//3 , the final temperature of the gas will be

When an ideal gas expands in vacuum, no work is done because

For an ideal gas, in an isothermal process

The value of specific heat of an ideal gas, with rise in temperature

If pressure of an ideal gas is decreased by 10% isothermally, then its volume will

Two moles of an ideal gas expand spontaneously into a vacuum. The work done is
