Asample of helium gas in a balloon is compressed from 4.0 l to 3.2 l at a constant temperature. if the pressure of the gas in the 4.0 l volume is 229 kpa, what will the new pressure?

286 kPa

Explanation:

Boyles law states that volume of gas is inversely proportional to pressure o gas for a fixed amount of gas at constant temperature

P1V1 = P2V2

where P1 is pressure and V1 is volume at first instance

P2 is pressure and V2 is volume at the second instance

substituting the values in the equation

229 kPa x 4.0 L = P2 x 3.2 L

P2 = 286.25 kPa

the new pressure is 286 kPa
