    There is a sample of diatomic gas in a container (whose volume is constant). The temperature of this gas was increased greatly so some molecules fell into atoms (dissociated). The pressure of the gas increased by a factor of 6 and the internal energy of the gas increased to a value of 4.4 times the original internal energy. By what factor did the temperature of the gas (measured in Kelvin) increases?

    We give 90 J as heat to a diatomic gas, which then expands at constant pressure. The gas molecules rotate but do not oscillate. By how much does the internal energy of the gas increase?

    Consider a gas filled in a part of thermally insulated vessel with frictionless insulated piston (connected to a massless spring). Natural length of the spring equals length of the vessel. For 30 J of heat supplied, internal energy of gas increases by 25 J. find the number of atoms in one molecule.

    A monatomic gas expands at constant pressure on heating. The percentage of heat supplied that increases the internal energy of the gas and that is involed in the expansion is
