... When two bodies, liquids, solutions, solidliquid, etc.,(*) initially at different temperatures, are put in contact or mixed, the amount of heat absorbed and given off by the two samples have the same absolute value, but one is >0 and the other is <0. That happens until they reach the thermal equilib ...

... Because heat, Q, work, W, and the change in internal energy, ΔU, are, in general, signed quantities, the above equation go beyond recapitulating the bare facts of Joule’s experiments. The work may be done on or by the system or not at all (W > 0, W < 0, or W = 0) and by any means (mechanical, electr ...
