Question

What is going to happen to the volume of a gas that is put under MORE pressure while keeping the temperature constant?

A) The volume will increase.
B) The volume will decrease.
C) The volume will fluctuate.
D) The volume will remain constant.

Answer 1

Boyle's law states that in an ideal gas system, pressure and volume have an inverse relationship when the temperature remains constant. So B.

Answer 2

Answer: B) The volume will decrease.

Explanation: Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

`P\propto (1)/(V)` (At constant temperature and number of moles)

`{P_1V_1}={P_2V_2}`

where,

`P_1` = initial pressure of gas = x

`P_2` = final pressure of gas = say if doubles = 2x

`V_1` = initial volume of gas = v

`V_2` = final volume of gas =
`V_2`

`{x* v}={2x* V_2}`

`V_2=(v)/(2)`

Thus volume will decrease.
