At what temperature will sound travel through the monatomic gas helium at the same speed at which it travels through air at 2°C? The atomic mass of helium is 4.003 u and the value for the ratio of the specific heats for an ideal monatomic gas is γ = 1.67. (Enter your answer to at least the nearest degree.)
