Energy Transfer Temperature

Which of the following correctly identifies a method of heat transfer that will happen in this situation?

• Heat will be transferred from the hot plate to the thermometer through radiation.

• Heat will be transferred from the beaker to the thermometer through convection.

• Heat will be transferred from the hot plate to the beaker through convection.

• Heat will be transferred from the thermometer to the beaker through conduction.

Radiation is a method of thermal energy transfer. It refers to the transfer of heat energy that moves–

• through empty space.

• when objects touch.

• only through solids.

• in the motion of fluids.

Conduction can only occur between two objects when–

• one object is less dense than the other.

• both objects are in physical contact with each other.

• one of the objects is made of a metal.

• both objects are exactly the same temperature.

Which of the following is an example of a situation in which an egg is receiving thermal energy through convection?

• Which of the following is an example of a situation in which an egg is receiving thermal energy through convection?

• An egg is fried in a metal pan on the stove.

• An egg cracked on a hot sidewalk starts to cook.

• The egg is cooked in a pot of water on the stove.
