• No, only the size was the same.

Did the glasses contain the same amount of liquid?

• No

• Yes

• Only approximately the same.

• The text doesn't say.

Which drink had the largest temperature difference from the room temperature?

• Iced Tea

• Hot Chocolate

• Both were equal

• Neither; they were both at room temperature.

What process would most likely cause the iced tea to warm up?

• Evaporation

• Condensation

• Heat transfer from the surroundings

• Chemical reaction

What process would most likely cause the hot chocolate to cool down?

• Evaporation

• Condensation

• Heat transfer from the surroundings

• Chemical reaction

What are the different methods of heat transfer?

• conduction, radiation, and reflection

• conduction, reflection, and convection

• convection, radiation, and reflection

• conduction, radiation, and convection

Considering only the temperature difference between the drinks and the room, which drink would you expect to change temperature more rapidly?

• Iced tea, because it has a smaller temperature difference to overcome.

• Hot chocolate, because it has a larger temperature difference.

• Both at the same rate.

• Neither, as other factors are more important.
