ILTS CONTENT TEST ELEMENTARY ED(305)-PART 3/6 EXAM 2024 4 basic laws of thermodynamics - correct answer zeroth law: states that 2 objects in thermodynamic equilibrium with a 3rd object are also in equilibrium with each other 1st law: states that neither mass nor energy can be destroyed; only converted from 1 form to another(conservation of energy) 2nd law: states that the entropy of an isolated system can only increase; heat is not transferred from low temp system to a higher temp system one unless additional work is done 3rd law: states that as a temperature approaches absolute 0, entropy approaches a constant minimum; system can not be cooled to absolute 0. compare and contrast heat and temperature - correct answer heat: energy transfer from 1 body or system to another due to thermal contact temperature: measurement of an object's stored heat energy mass - correct answer measures how much of a substance is in an object weight - correct answer measures the gravitational pull of the earth on an object
