2. The temperature of a gas is increased from 125°C to 182°C inside of a rigid
container. The original pressure of the gas was 1.22atm, what will the pressure of
the gas be after the temperature change?

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
