$\huge\underline{Answer}$

You should never throw an aerosol can onto a fire or leave it in direct sunlight – even if it is empty. This is because the pressure will build so up so much that the can will burst (and explode if there is a naked flame nearby). ... the gas pressure increases. more of the liquefied propellant turns into a gas.
