A litre of dry air at STP expands adiabatically to a volume of 3l. If , then work done (in J) by air is
[take air to be an ideal gas]:-
In an adiabatic process, the density of a diatomic gas becomes 32 times its initial value. The final pressure of the gas is found to be n times the initial pressure. The value of n is :
To raise the temperature of a certain mass of gas by at a constant pressure,
calories of heat is required. When the same mass of gas is cooled by
at constant volume,
calories of heat is released. How many degrees of freedom does each molecule of this gas have (assume gas to be ideal )?
