True or False: both gases and solids can expand or contract depending on temperature?
True
True or False: Temperature and Thermal Energy are the same.
False
What is the decrease in volume when particle motion decreases?
Thermal Contraction
Adding thermal energy to a cup of water may cause the particles to ______________.
Move faster, spread apart, or collide more often
What are the two types of Vaporization?
Evaporation and Boiling
Put the states of matter in order of particle speed with the FIRST being the FASTEST moving and the THIRD being the SLOWEST moving.
Gas = fastest, Liquid = second, Solid = slowest
