Question

Inverse variation ?
Boyle’s law says that the volume of a gas varies inversely with the pressure. When the volume of a certain gas is 20 L, the pressure is 132 Kpa (kilo Pascal) what is the pressure when the volume is 15 L?

Answer 1

Answer:

The pressure will be 176 k Pa

Step-by-step explanation:

Boyle's law states that the product of volume and pressure gives us a constant value so we can write the expression as

P1V1 = P2V2

By arranging the equation we get

P1V1 / V2 = P2

Putting the values

(132 x 20 ) / 15 = P2

P2 = 176 k Pa
