Liquid water 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 of liquid water collected in separate 10 L containers at 1 atm. Will the temperatures of the gases be equal? In one to two sentences, use the ideal gas law to explain your answer

1 answer

No, the temperatures of the gases will not be equal. According to the ideal gas law, at constant pressure and volume, the temperature of a gas is directly proportional to its molar quantity, so since the hydrogen gas and oxygen gas were produced in different molar quantities, their temperatures will be different.
