On aerosol deodorant cans, the symbol of flammable is clearly shown. What happens when the can is exposed to high temperature?

Its outcome if applicable to Charles law

The can expands and is directly proportional to the temperature

The pressure of the can increases, resulting in explosion.

The volume of the content increases, resulting in explosion.

The propellant inside the can (usually a mixture of propane, butane, and/or isobutene) can become vaporized and ignite, resulting in an explosion or fire. This is due to a combination of the high temperature causing the propellant to expand and the pressure inside the can increasing, causing it to rupture. This outcome is not applicable to Charles' Law, which deals with the relationship between volume and temperature of a gas while keeping pressure constant.
