Gas Law II - Charles' Law

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

$V \propto T$

Where,

$V$ - volume of the gas

$T$ - temperature of the gas

Using this,

$\frac{V}{T} = c o n s t a n t$

Q 1

. A gas originally has a volume of

15 m^{3}

and is expanded to a volume of

30 m^{3}

. Given that the pressure remains constant and the initial temperature was

20^{\circ} C

, calculate the final temperature of the gas.

Q 2

. A gas expands to have a volume of

32 m^{3}

. Given that the pressure remains constant, the initial temperature was

20^{\circ} C

and the final temperature was

- 16^{\circ} C

, calculate the final temperature of the gas.
