How does a glass of juice become cold when you add ice to it?
a) Ice is colder than the juice. The cold travels from cold to warm until both items are the same temperature.
b) The juice is warmer than the ice. Heat travels in one direction until both items are the same temperature.
c) The ice makes the glass colder so the juice becomes colder.
d) The ice cools the glass of juice because the slow moving particles in the ice cause the particles of the juice to slow down.

How are thermal energy, heat and temperature related?
a) They are not related.
b) Temperature measures heat which caused thermal energy.
c) Thermal energy that is transferred from matter at a higher temperature to matter at a lower temperature is called heat.
d) Only heat and temperature are related.
