Heat Transfer Practice Questions

A student observes that an aluminum cup placed close to a burning candle becomes warm to touch. What method of heat transfer is responsible for the warming of the surface of the cup?

• conduction

• convection

• radiation

• sublimation

A student fills a beaker with water and places it over a burner. The student attaches a ball of wax on one end of a metal spoon and places the spoon in the beaker, as shown.

After a few minutes, the student observes that the ball of wax starts to melt. What explains the observation?

• Heat from the water in the beaker travels through the spoon to the ball of wax through radiation.

• Heat from the water in the beaker travels through the spoon to the ball of wax through convection.

• Heat from the water in the beaker travels through the spoon to the ball of wax through conduction.

• Heat from the water in the beaker travels through the spoon to the ball of wax through evaporation.

Henry is doing an experiment on heat transfer. He fills four beakers (A, B, C, and D) with water of different temperatures and places them in the same location at a temperature of 70°F.

Which statement best summarizes what will happen to the water in each of the beakers after a few hours?

• The water in each beaker will match the temperature of beaker A.

• The water in each beaker will be 20 degrees cooler.

• The water in each beaker will be 20 degrees warmer.

• The water in each beaker will be close to the same temperature.

Alex heats his soup on a heat source.

Which statement best explains this process?

• The soup that is closer to the heat source is hotter than the soup near the surface, and it rises to the surface.

• The soup that is closer to the heat source is cooler than the soup near the surface, and it sinks to the bottom.

• The soup that is closer to the heat source is the same temperature as the soup near the surface, and there is no movement.

• The soup that is closer to the heat source and at the surface is coldest, and only the soup in the middle is hot.

Thermal energy always moves:

• From a high temperature object to a lower temperature object.
• From a lower temperature object to a higher temperature object.
• From an object with lower kinetic energy to an object with higher kinetic energy.
• From an object of higher mass to an object of lower mass.

A block of ice is placed on a hot sidewalk. The ice melts because

• the energy from the ice flows to the sidewalk.
• the energy from the sidewalk flows to the ice.
• convection currents flow between the ice and the sidewalk
• radiation flows between the ice and the sidewalk
