Question:medium

At which temperature will the r.m.s. velocity of a hydrogen molecule be equal to that of an oxygen molecule at \( 47^\circ \text{C} \)?

Show Hint

The r.m.s. velocity is influenced by both the temperature and the molar mass of the gas. Use the proportionality \( v_{\text{rms}} \propto \sqrt{\frac{T}{M}} \) to connect the properties of different gases.
