Use the diagram to answer the question that follows.

Which process is responsible for moving hot air from inside the stove to the outside?

• convection

• reflection

• radiation

• conduction

A student standing near a campfire feels warmer as the fire grows. Which process most likely transfers heat from the campfire to the student?

• conduction

• convection

• radiation

• transformation

When two objects are touching, heat is transferred from the warmer object to the cooler one by

• radiation.

• convection.

• conduction.

• connectivity.

Hot objects begin to cool as

• cooler air is transferred to the object.

• energy in the object is transferred to the surrounding air.

• atoms in the object react with the oxygen in the air.

• energy in the object cancel out energy in the air.

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.

Miranda wraps her hands around a mug of hot tea.

The heat from the hot tea is being transferred to Miranda’s hands primarily by

• conduction.

• convection.

• absorption.

• radiation.

A black brick exposed to sunlight becomes warm. How is energy from the Sun transferred to the brick?

• convection

• conduction

• radiation

• reflection

A pot is touching the flame of a gas stove and the substance in the pot is heating up due to the contact. This is an example of which type of energy transfer?

• radiation

• convection

• conduction

• vaporization

Molly was making iced tea by putting tea bags in boiling water. She needed to cool the hot tea quickly, so she poured it into a pitcher full of ice. Which best describes the flow of thermal energy?

• from the ice to the tea

• from the tea to the ice

• from the pitcher to the tea

• from the ice to the pitcher
