ILTS Content Test Elementary Ed(305)-Part 3/6 Questions and Answers 100% Correct! 4 basic laws of thermodynamics - ANSWERszeroth 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 - ANSWERsheat: energy transfer from 1 body or system to another due to thermal contact temperature: measurement of an object's stored heat energy mass - ANSWERsmeasures how much of a substance is in an object weight - ANSWERsmeasures the gravitational pull of the earth on an object density - ANSWERsa measure of the amount of mass in a given volume D=m/V volume - ANSWERsmeasures the amount of space taken up specific gravity - ANSWERsmeasures the ratio of a substance's density to the density of water thermal contact - ANSWERsenergy transferred to a body by a means other than work heat - ANSWERsThe energy transferred between objects that are at different temperatures Models for the flow of electric charge - ANSWERsused to explain the flow of electric current, potential, circuits include water, gravity and roller coasters magnetic field - ANSWERsmotion of subatomic structures(nuclei and electrons) produce magnetic field; formed not only by magnetic material but also by electric current flowing through a wire magnetic moment - ANSWERsThe strength of a magnetic field electric charges as they relate to atomic structure - ANSWERselectric force: attractive force between the electrons and the nucleus *electrical field: positive or negative charge creates a field of sorts in the empty space around it *electric charge: measured with unit Coulomb(C) is the amount of charge moved in 1 second by a steady current of one ampere(1C=1Ax1s electric current - ANSWERsThe continuous flow of electric charges through a material rate of flow of electric charge - ANSWERsexpressed using the ampere(amp or A) and can be measured using an ammeter simple circuit - ANSWERsa circuit that has only one pathway for electricity to flow through. e
