What is increases?
Describe particle motion in a liquid.
What is particles slide past eachother?
Which type of heat transfer occurs in solids best?

Explain the difference between temperature and thermal energy.
Temperature measures average particle motion; thermal energy is total energy of all particles.

What is when it slows down?
Explain how convection works in boiling water.
What is warm water rises and cool water sinks, creating currents?
Why does temperature stay the same during a phase change?
What is energy is used to change particle arrangement, not temperature?
Why do mittens keep your hands warm in winter?
What is they reduce heat loss by trapping air?
