Which of the following laws gives the relation between volume and temperature?
Which of the following laws gives the relation between volume and temperature?
Boyle's law
Charles' law
Gay-Lussac's law
Avogadro's law
Solution
Charles' law states that, the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure.
At constant pressue, $V \propto T$
Or $\quad \frac{V_1}{V_2}=\frac{T_1}{T_2}$
Hence, the correct option is (2).
