Question

A System absorbs 710 J of heat and does work
The change the internal energy for the
process is 460J the work done by the
system is​

Answer 1

Answer:

The system absorbs 640 J and the work system does on surroundings is 260J. Therefore by the first law of thermodynamics, the internal energy of the system increases by:

△U=q−W=(640−260)=+380 J.
