Document Summary

Name: gisele ghiassy: surface tension: a measure of how difficult it is to stretch or break the surface of a liquid. Heat and tempurature: kinetic energy (anything that moves has this) the energy of motion. The faster they move the more kinetic energy they have: heat is a form of energy. Amount of heat is a measure of the matter"s total kinetic energy (technically heat depends in part on the matter"s volume: temperature is a measure of heat intensity that rep. the average kinetic energy of the molecules. When you boil water the speed/ motion of molecules increase causes its hotter. Which lets the temperature to rise (yet the greater the volume the more the heat) An ice cube absorbs the heat from the hot liquid as the ice melts.
