Thermochem questions
« on: October 26, 2018, 07:13:54 PM »
I have two questions.

According to the First Law of Thermodynamics, changes in work must be equal and opposite to changes in heat for a CLOSED system. Is that true or false?

Also, can the total change in energy (U) for a system come from work alone?
