Benchmark 2 study guide Flashcards
When the temperature goes up, what happens to the speed of the particles
the speed increases
when speed of particles increases, what happens to the kinetic energy
the kinetic energy increases
what does a substance undergoes when it changes from solid to liquid
melting point
what is the temperature of a substance related to
kinetic energy particle motion
if a solid is heated, what happens to the particles
they speed up and spread out more. They can melt and turn into liquid
what is kinetic energy
Energy in motion
what is potential energy
stored energy
how can you find out how much kinetic energy an object has
temperature
