Question

3. A sample of nitrogen gas has a volume of 478 cm3 and a pressure of 104.1 kPa. What volume would the gas occupy at 88.2 kPa if the temperature remains constant? b.23nit c 2'0L Oso loydbolsyn

Answer 1

According to Boyle’s law, at constant temperature volume of a given gas varies inversely with pressure of that gas. Mathematical expression is given as follows:

P1V1 = P2V2

Where, P1 = Initial pressure; P2 = final pressure, V1=initial volume and V2 = final volume

For a given sample of nitrogen gas substitute, P1=104.1 kPa, V1 = 478 cm³, P2 = 88.2 kPa.

104.1 kPa x 478 cm³ = 88.2 kPa x V2

V2 = (104.1 kPa x 478 cm³ ) / (88.2 kPa)

V2 = 564 cm³

Thus, volume occupied by given volume of nitrogen gas at pressure of 88.2 kPa is 564 cm³
