Sandy has just made a pitcher of hot tea. She pours the tea into a cup and picks it up. The cup acts as an insulator, so Sandy can pick up the cup even though the liquid inside is hot. Of what material could the cup be made?
plastic
wood
glass
all of these

reflection
conduction
radiation
convection
A slice of cheese is 3.0°C and is sitting on a dish that is 3.0°C. If the dish and cheese are in a refrigerator that is set to 3.0°C, which of the following statements is true?
The temperature of the cheese will increase and the temperature of the dish will decrease.
Heat will flow from the air in the refrigerator to the cheese and the dish.
Heat will not flow because there is no temperature difference between the substances.
The temperature of the air in the refrigerator will decrease and the temperature of the cheese will increase.
