physical or phase changes
how would we write the enthalpy equations for the reverse of vaporization, melting, and sublimation?

Re: physical or phase changes
For the reverse reactions, you would just take the negative value of the change in enthalpy, which indicates whether heat is absorbed or released.

Re: physical or phase changes
When you reverse one of those reactions, this means that instead of absorbing, you will be releasing heat, and vice versa. So, add a negative in front of the change in enthalpy they already give you.
