9 Weeks Exam Heat Transfer & Layers of the Earth

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.

Look at the picture provided. In the situation illustrated, how will heat energy move? Heat energy will be transferred from –

• the hot plate to the beaker.

• the beaker to the hot plate.

• the thermometer to the beaker.

• the beaker to the thermometer.

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.

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

• The egg is kept warm by its mother in the nest.

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

• The egg is hard boiled in a pot of water.

• A metal pan on the stove fries the egg.

Three metal cubes with different temperatures are placed side-by-side as shown in the picture provided. Which of the following describes a way in which heat energy will be transferred by conduction.

• Sample 1 to Sample 2

• Sample 3 to Sample 2

• Sample 3 to Sample 1

• Sample 2 to Sample 3
