Conductor
300
What method of energy transfer is this?
(Description: Heat flows from the hotter cup into the cooler hands. )
Conduction (energy transfer via contact)

What happens to molecules when the temperature reaches absolute zero?
All of their motion stops
300
What device can you use to measure temperature?
Thermometer

Explain why a metal spoon feels warmer than a plastic one in the same cup of hot tea. Use the terms insulator and conductor.
The plastic spoon is an insulator, so does not conduct heat from the tea. The metal spoon is a conductor and it will absorb the heat from the tea, making it feel warmer.

What method of heat transfer is shown here?
Convection heating (hot fluid rises, cool fluid sinks)
400
Which object has more thermal energy, an ice berg or a pot of boiling water? Explain.
Iceberg because there is more mass

Explain one example of a conductor and one example of an insulator you use while cooking.
An oven mitt, rubber-coated handles on pans and pots, and rubber and plastic utensils are all examples of insulators. Pots, pans, and metal baking sheets are all examples of conductors.
