If the uncompressed has in the above system has a volume of 300.0 mL at a pressure of 20.0 kPa what is the volume of the gas when it is compressed to a pressure of 25.0 kPa

240 ml

Explanation:

Initial Volume V1 = 300 ml

Initial Pressure P1 = 20.0 kPa

Final Pressure P2 = 25 kPa

Final Volume V2 = ?

These quantities are related by boyles law which is given as;

V1P1 = V2P2

Making V2 subject of interest;

V2 = V1P1 / P2

Upon inserting the values;

V2 = 300 * 20 / 25

V2 = 240 ml
