Question

Boyle's Law says that the volume of a gas varies inversely with the pressure. When the volume of a certain gas is 5L , the pressure is 452 kPa (kilopascals). What is the volume when the pressure is 565 kPa?

Answer 1

If the volume varies inversely with pressure then

V*P = k

where V = volume, P = pressure

So

5*452 = k

and

V*565 = k

which means

5*452 = V*565

2260 = V*565

2260/565 = V

4 = V

V = 4

Which means that the volume of the gas is 4 liters
