Gas Law I - Boyle's Law

At a constant temperature, experiments show that the pressure and volume of a gas are inversely proportional.

$p \propto \frac{1}{V}$

Where,

$p$ - pressure of the gas

$V$ - volume of the gas

Using this,

$p V = c o n s t a n t$

Q 1

. A gas is kept at constant temperature. Initially the gas is at

32 P a

and a occupies a volume of

5 m^{3}

. After some change to the environment, the final pressure is

28 P a

. Calculate the final volume the gas would occupy.

Q 2

. A gas is kept at constant temperature. The gas initially is held at

200 P a

at a volume of

20 m^{3}

. It is decompressed to a volume of

7 m^{3}

. Calculate the final pressure exerted by the gas.
