The pressure of a gas is 0.975 atm when its volume is 400 ml. calculate the pressure if the gas is allowed to expand to 600 ml at constant temperature.

Respuesta :

The correct answer is = 0.65 atm pressure.

1) the Boyle's law state that the volume of a gas inversely expand proportional to the pressure. it means an ideal gas under constant temperature the product of pressure and volume is always constant provided there is no change in the number of moles of gas.

PV = constant

P1V1 = P2V2

by using the Boyle's law formulae,

2) The pressure of a gas (P1) = 0.975 atm

Volume of a gas (V1)           = 400ml

The temperature = constant

To find out the pressure(P2) of a gas at constant temperature = ?

P1V1 = P2V2

0.975×400 = 600 × (P2)

P2 = 0.65 atm

The Boyle's law is used when temperature is constant then the product of pressure and volume is constant.

This is only applicable at constant temperature.

The correct answer is 0.65 atm

1)The Boyle's law states that at constant temperature the product of pressure and volume becomes constant.

  • PV= constant
  • P∝  1/T
  • The pressure is inversely proportional to the volume when temperature is constant,
  • Also the formulae formed is P1V1 = P2V2

2) The initial pressures of a gas = 0.975 atm

The initial volume (V2) = 400ml

The final volume when gas allowed to expand (V2)= 600 ml

The final pressure of a gas = need to find out

The temperature is = constant

Using the above formulae,

P1V1 = P2V2

0.975×400 = 600 × P2

P2 = 0.65 atm

3)The Boyle's law applicable only when the temperature is constant then the pressure is inversely proportional to the volume.
