Why do hair spray or paint which contain gas under pressure contain a warning to keep them away from heat or fire?
Science question.?
According to ideal gas law, (P * V) / T is a constant. Where P is pressure, V is volume and T is temperature.
If the temperature rises, then if the volume is kept constant, then the pressure will rise too.
The "can" holding the gas wont be able to hold for a very big pressure, so it could explode.
Oh, and they also contain highly flammable gas.
Hope it helps

Science question.?
The chemicals that compose those formulas are highly flammable...
Science question.?
if brought to close and kept near a flame, the pressurized air in hair spray and spray paint will heat up and expand and possibly cause the can to explode. also, hair spray and spray paint, most times, contain very flammable substances.
