Question

Using the appropriate gas law , explain why there are warnings on aerosol can instructing not dispose of them by incineration.indicate which gas law explains this warning

Answer 1

We can say that what's happening in the aerosol can is an isochoric process, as the volume of the can remains the same. We can assume behavior of ideal gas for the substance inside the can. Now, considering this behavior, and having an isochoric process, the can should not be disposed by incineration due to the following law:

P₂ = P₁ * (T₂/T₁)

We can see that as temperature is increased, pressure will also increase, and as the pressure is already wquite high, the can might explode within seconds.
