Heat Transfer Questions

On a summer day, a puddle of water on the road heats up and evaporates, turning into water vapor. How does heat transfer occur in this situation?

• The Sun transfers heat by conduction, and the road transfers heat by convection and conduction.

• The Sun transfers heat by conduction, and the road transfers heat by radiation and convection.

• The Sun transfers heat by convection, and the road transfers heat by radiation and conduction.

• The Sun transfers heat by radiation, and the road transfers heat by convection and conduction.

A chef pours cold water in a pot, places the pot on a stove, and turns on the burner. What kind of heat transfer will occur?

• The heat from the stove burner will cool the metal pot through convection, causing conduction to cool the water.

• The heat from the stove burner will heat the metal pot through convection, causing conduction to heat the water.

• The heat from the stove burner will cool the metal pot through conduction, causing convection to cool the water.

• The heat from the stove burner will heat the metal pot through conduction, causing convection to heat the water.

A student notices that macaroni placed in a beaker of boiling water moves in a circular path around the beaker, as shown in the diagram. A classmate says that this occurs due to convection.

Which statement best describes why the classmate is correct or incorrect?

• The classmate is correct; when heat is transferred by fluid particles moving in a circular direction, it is called convection.

• The classmate is incorrect; when heat is transferred by fluid particles moving in a circular direction, it is called conduction.

• The classmate is correct; when the heat transfer occurs due to the direct contact between the materials, it is called convection.

• The classmate is incorrect; when the heat transfer occurs due to the direct contact between the materials, it is called conduction.

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.

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.

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.
