Question

The volume of given mass of a gas is 0.6 dm³ at a pressure of 101.325K Pa. Calculate the volume of the gas if its pressure is increased to 142.860KPa at the same temperature.

Answer 1

of 101.325K Pa. Calculate the volume of the gas if its pressure is increased to 142.860KPa at the same temperature.

Answer 2

Answer:

Explanation:

Given The volume of given mass of a gas is 0.6 dm³ at a pressure of 101.325 K Pa. Calculate the volume of the gas if its pressure is increased to 142.860 KPa at the same temperature.

Given  initial volume = V1 = 0.6 dm^3

Initial pressure = p1 = 101.325 k pa

Final pressure = p2 = 142.860 k pa

We need to find the final volume v2

So from Boyle’s law at constant temperature we get

       P1v1 = p2v2

      So v2 = p1v1 / p2

       V2 = 101.325 k pa x 0.6 dm^3 / 142.860 k pa

      V2 = 60.795 dm^3 / 142.860

      V2 = 0.425 dm^3

So the volume of the gas is 0.425 dm^3
