A car is parked outside in the sun. The temperature of the interior of the car reaches 55 Celsius. However a company claims their product, a special spray, can cool down the temperature inside the car down to 25 Celsius in just a few seconds. The spray is a mixture of ten percent alcohol and 90 percent water. How does the spray work?

Worth 3 marks!

please help.

I was thinking it has to do with the specific heat capacity of water and thermodynamics :/

oh and btw, this unit is on enthalpy.

Oh ok cuz I thought this was familiar. You can try tagging different people to see. Or you can ask in physics too I think.
