Answer:
The volume of the gas got doubled.
Explanation:
Charle's law states that the volume of an ideal gas is direclty proportional to the absolute temperature.
Thus, V ∝ T
Or,
[tex]\frac {V_1}{T_1}=\frac {V_2}{T_2}[/tex]
If the bottle is heated to the double of the temperature, the volume of the gas also gets doubled.
