Liquid water can can be separated into hydrogen gas and oxygen gas through electrolysis. 1 mole of hydrogen gas and 0.5 moles of oxygen gas is produced from 1 mole if liquid water collected in separate 10 L containers at 1atm. Will the temperature of the gasses be equal? In one to two sentences, use the ideal gas law to explain your answer.

1 answer

Yes, the temperatures of the hydrogen gas and oxygen gas will be equal, as they are produced under the same conditions of pressure and volume. According to the ideal gas law (PV=nRT), if the two gases occupy the same volume (10 L) and are at the same pressure (1 atm), then the temperature (T) must be the same for both gases, regardless of their different amounts of moles (1 mole of H₂ and 0.5 moles of O₂).
