Sam went to a park on a hot summer day. He wanted to slide down the steel slide but realized it was too hot. Which statement explains why the slide was hot?

• Heat was transferred to the slide by radiation.

• Heat was transferred to the slide by convection.

• Heat was transferred to the slide by conduction.

• Heat was transferred to the slide by transpiration.

While riding his bike, Dawson starts to notice his face and shoulders beginning to burn. How is this most likely occurring?

• due to radiation from the sun

• due to conduction from his bike

• due to convection causing a hot wind

• due to evaporation of sweat on his skin

Which best describes how heat is transferred due to convection?

• through direct contact with a hot object

• through the movement of gases or liquids

• through the absorption of the sun’s energy

• through the process of liquid changing into a gas

Which processes occur when a pot of water placed on a hot stove causes the water to boil?

• The pot heats because of conduction, and radiation causes movement of the water.

• The pot heats because of radiation, and convection causes movement of the water.

• The pot heats because of conduction, and convection causes movement of the water.

• The pot heats because of convection, and conduction causes movement of the water.

Convection will cause which to occur?

• melted marshmallow

• hot pavement

• strong winds

• burnt eggs

This illustration shows how heat can move through the atmosphere as air circulates.

What causes the circulation of air?

• Air in the atmosphere is heated by the Sun and sinks to the ground.

• The ground is heated by the Sun and then heats the air, causing the air to rise.

• Air loses heat to the ground and then rises upward to obtain more energy.

• The Sun heats the clouds which forces the cooler air to move away and sink.
