I am doing a project where I have to start with a solid, show is turning into a liguid and then a gas..Can I use butter as a solid, melt it in cookies, and then bake the cookies showing that it turns into a gas (or by smell of butter in cookies). Thank you
Yes, but it would be very difficult to show the butter has been melted in the cookies (and especially the gas part).
Boiling butter would probably be better. You start with a solid, it melts to a liquid, and then becomes a gas.
Boiling ice would be easiest, though.
I definately agree with Michael.
