Final answer:
If the temperature of the gas mixture in an aerosol can increases while the volume remains constant, the pressure inside the can will increase, potentially leading to the can bursting especially due to the combustible nature of gases like isobutane.
Step-by-step explanation:
When the temperature of a gas mixture inside an aerosol can increases at a constant volume, according to Amontons's law, the average speed and kinetic energy of the gas molecules will also increase. Since the can's volume remains unchanged, this results in more frequent and forceful collisions of gas molecules with the can's walls, leading to an increase in pressure. If the temperature reaches very high levels, such as those achieved during incineration, the pressure could rise to the point where the can might burst, especially since isobutane, the gas commonly found in aerosol cans, is combustible and could exacerbate the increase in pressure.
