how can i create heat by using gases? i have to do a science project for school and i chose to invent something. it is a 'hairdryer in a can' a hairdryer in an aerosol can (thus requiring no batteries etc. and easily portable). and i am trying to find out how i can cause heat to come out of the nozzle when it is pushed. i know that deoderant is very cold when it comes out of the nozzle, can one reverse this process to create heat with gases? if this is not possible, do you have any suggestions (on how to generate heat without electricity)?
