Explanation / Answer
The first law of thermodynamics, an expressionof the principle of conservation of energy, states that energy canbe transformed (changed from one form to another), but cannot becreated or destroyed. Or
The increase in the internal energy of a system isequal to the amount of energy added by heating the system, minusthe amount lost as a result of the work done by the system on itssurroundings.Related Questions
