Assuming the room temperature is greater than the temperature of the ice water shown below, select all the following statements that are true.
Heat flows from the ice cubes into the water.
Heat flows from the water into the ice cubes.
Heat flows from the cup into the air in the room.
Heat from the air in the room flows into the cup.
There is no heat flow between the ice cubes and the water because they are at equilibrium.

Imagine that it's your job to pick the material for a railing in a very cold climate. Which material from the table would feel the least cold if you touched it in freezing temperatures? Assume that each material would have the same temperature when touched.
hardwoods
copper
aluminum
plywood
limestone
If you take a baked pototo out of the oven and remove the foil, you'll notice that the foil cools down quickly. However, it's unwise to bite the potato right when the foil cools because it will still be very hot. What is the reason for this?
the foil's high thermal capacity keeps the potato warm
the foil's thermal conductivity is low and the potato's is high
the foil has higher thermal conductivity and lower heat capacity than the potato
radiation from the foil keeps the potato hot
What kind of heat transfer is being shown in this image?
convection
conduction
radiation
______ is the heat transfer that allows for me to feel that this stove coil is hot without actually touching it.
convection
conduction
radiation
Two of the following changes of state happen when thermal energy is taken away:
Melting
Freezing
Condensation

Sublimation
Deposition
Which of the following statements describes the particle arrangement and motion within a solid?
relatively close together; can move a little and even flow
spread far apart; electroncs move independently from the ions
spread far apart; move freely and rapidly
packed tightly together; move or vibrate very little
If a material does not allow charges to move through it easily, what is it called?
electrical insulator
electrical conductor
static electricity
electric discharge
Which material would require the most energy to heat up by one degree Celsius? (Hint: Some materials require more energy to be added to increase their temperature by one degree.)
