Question #111816
6.A gas occupies a volume of 400cm3 at 500k and 1 atmosphere pressure. What will be the temperature of the gas when the volumeand pressure of the gas is 100cm3and 0.5atmospheres respectively?(2 marks
Expert's answer
According to the combined gas law equation:
p1V1/T1 = p2V2/T2
where p1 - initial pressure, V1 - initial volume, T1 - initial temperature, p2 - final pressure, V2 - final volume, T2 - final temperature.
From here:
T2 = p2V2T1 / p1V1
As a result:
T2 = (0.5 atm × 100 cm3 × 500 K) / (1 atm × 400 cm3) = 62.5 K
Answer: 62.5 K
