Apiston in a heat engine does 500 joules of work, and 1,400 joules of heat are added to the system. determine the change in internal energy and explain how this example demonstrates the conservation of energy.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
