Position versus time
graph of position versus time with position on y axis from 0 to 120 miles and time on x axis from 0 to 5 hours. segment 1 goes from 0, 0 to 1, 20. segment 2 goes from 1, 20 to 2, 40. segment 3 goes from 2, 40 to 3, 70. segment 4 goes from 3, 70 to 5, 85.

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
