Density how tightly packed atoms are
does energy take up space? No! It has no mass or volume
High density tightly packedparticles and object will sink
How does heat move? from WARM to COLD until both are equal temperatures
is energy matter? NO
Low density particles are spread out and object floats
pressure a pushing force caused by collisions
radiation WAVES of heat energy (empty space)
temperature average speed of moving particles
what happens when an object cools down? the space between the particles SHRINK
what happens when something is heated up? the space between particles EXPAND
what happens when you add heat to particles? the move FASTER
