Question

A system delivers 222 j of heat to the surroundings while delivering 645 j of work. What is the change in the internal energy, u, of the system?

Answer 1

Answer:

One of the thermodynamic properties of a system is its internal energy, E, which is the sum of the kinetic and potential energies of the particles that form the system. The internal energy of a system can be understood by examining the simplest possible system: an ideal gas.
