Question

what happens to the volume of a gas when its temperature increases (according to charles law)?
volume remains the same
volume decreases
volume doubles
volume becomes negative
volume increases

Explanation:

Charles' Law states that for a given mass of gas at constant pressure, the volume \( V \) is directly proportional to the absolute temperature \( T \) (in Kelvin), expressed as \( \frac{V_1}{T_1}=\frac{V_2}{T_2} \). When temperature \( T \) increases (assuming pressure and amount of gas are constant), since \( V \propto T \), the volume \( V \) must increase.

Answer:

Volume increases
