for the first option work is being done on the system , so there must be an increase in internal energy reight? this is confusing me.. as water is BEING freezed
however, for the third option the water is evaporating , meaning work is done BY the system... so internal energy must decrease... because increae in the internal energy is work done on the system and heat is supplied to the system....
can youclear my confusion?
Alright but in an hour. I was about to sign out and take a nap before seeing this. I'll grab my notes later and explain to you properly. My apologies for not answering immediately. My brain is shutting down already But i'll remember to reply this.
