A can of hair spray is used until it is empty except for the propellant,isobutene gas.

a) On the can is the warning "store only at temperature below 120'F(48.8'C). Do not incinerate. Why?

b) The gas in the can is initially at 24'C and 360 kPa and the can has the volume of 350mL. If the can is left in a car that reaches 50'C on a hot day,what is the new pressure in the can?
