A gas sample occupies 6.2 L at a pressure of 201 kPa. What volume will it occupy if the pressure is increased to 335 kPa? The temperature remains the same.

The volume of the gas at the increased pressure will decrease to 3.72L.

Explanation:

Boyle's law states that the volume occupied by a fixed mass of gas is inversely proportional to the pressure, provided temperature is kept constant. That is,

PV=K

P1V1 =P2V2

P1= 201 kpa

V1 = 6.2L

P2= 335kpa

V2= ?

Making V2 the subject of formula,

V2= P1V1/P2

V2= 201× 6.2/335

V2= 1246.2/336

V2= 3.72L

Thus, the volume of the gas decreases as the pressure increases. Hope this helps, thanks

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
