To raise the temperature of a certain mass of gas by $\displaystyle 50$°C at a constant pressure, $\displaystyle 160$ calories of heat is required. When the same mass of gas is cooled by $\displaystyle 100^{\circ} \mathrm{C}$ at constant volume, $\displaystyle 240$ calories of heat is released. How many degrees of freedom does each molecule of this gas have (assume gas to be ideal) ?
Official answer
(3)
$\displaystyle 6$
