Which method of heat transfer involves direct contact?

• Conduction

• Convection

• Evaporation

• Radiation

Why did the thinner copper rod melt the chocolate faster?

• It was made of a different material.

• It had fewer atoms, so it heated up faster.

• It was closer to the heat source.

• It had more atoms.

What does temperature measure?

• The total thermal energy in an object.

• The density of a substance.

• The speed of heat transfer.

• The average kinetic energy of atoms in a substance.

What causes the fog to rise in the convection demonstration?

• The fog is attracted to the ice.

• The fog is pushed by the wind.

• The fog is heated, decreasing its density.

• The fog is lighter than air.
