In case you missed the previous question, answer this: If the temperature in your room is 70 degrees Fahrenheit, and you leave a cup of hot tea (180 degrees) on the table, what is the temperature of the tea after several hours?

• 180 degrees

• 150 degrees

• 100 degrees

• about 70 degrees

Suppose I put a hot metal ball in the cup full of hot tea.....and then I leave the cup on the table for 10 hours. The room's temperature is still 70 degrees Fahrenheit. Which will be the hottest after 10 hours?

• metal ball

• the room

• hot tea

• They will all be the same temperature

Consider an oven. You have a metal pan in the oven and a ceramic dish. The temperature inside the oven is 400 degrees Fahrenheit. The objects have been there for a long time. Which of these is hotter?

• ceramic dish because it conducts so well!

• metal pan!! Metal simply gets hotter!

• Both objects are the same temperature.

Despain is going to show a simulation of 2 substances of equal mass and volume. Which of the two substances has a higher temperature?

• substance on the right

• substance on the left

Why does the substance on the left have a higher temperature?

• The molecules are moving faster.

• The substance is probably liquid and liquids are hotter.

• It has more molecules.

• The molecules are moving slower.

Consider the simulation, what do you predict will occur if Despain brings the two substances into "Thermal Contact" (they are touching in some way....)?

• Energy from the left will begin to transfer to the right.

• They will immediately become the same temperature.

• Nothing will happen

• Energy from the right will begin to transfer to the left.
