Heat and Temperature Test Review

The heat from a lamp allows a lizard to remain warm. This is an example of which type of heat transfer?

• radiation
• conduction
• convection
• insulation

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.

A lava lamp has cool globs of stuff that float up and down because of what?

• conduction

• convection

• radiation

• coolness

Heat transfer is really neat. It always moves from..

• hot to cold

• cold to hot

• big to little

• stop singing

As energy in the form of heat is added to an ice cube, it begins to melt. What causes melting.

• Heat causes the molecules to expanded and forces them apart.

• Heat removes thermal energy from the ice cube and causes it to become liquid water.

• Adding energy causes the bonds between the hydrogen and oxygen in the ice cube to break.

• The transfer of thermal energy to the ice cube causes its molecules to move faster.
