moving and storing heat

moving and storing heat

1. heat is a measure of energy

   • when a substance is heated the particles gain KE
     • energy makes particles in gas or liquid move faster
       • what causes liquids to boil
     • makes particles in a solid vibrate more rapidly
       • what causes it to melt

2. temperature is a measure of hotness

   • a measure of average KE of particles in a substance
     • the hotter something is the higher average KE of its particles
