Which of the following is an example of heat transfer by conduction?
A shirt warmed when it touches a hot iron
Warm and cold water circulating in the ocean
Sunlight warming a room early in the morning
Hot air rising and cold air sinking on a beach
- 11. Multiple ChoiceHot coffee is stirred with a spoon; the spoon gets hot due toconductionconvectionradiation
- 12. Multiple ChoiceA chair is several feet from a fireplace. The side of the chair facing the fireplace gets warm due toconductionconvectionradiation
- 13. Multiple Choice"Lava lamps" contain colored liquids. These liquids form globs that rise to the top due toconductionconvectionradiation
- 14. Multiple ChoiceNear the ceiling of a room the air is warmer; the warm air rises because ofconductionconvectionradiation
- 15. Multiple ChoiceIn a swimming pool, water near the surface is slightly warmer. The warm water rises because ofconductionconvectionradiation
- 16. Multiple ChoiceA house burns down. The vinyl siding of the house next door warps due toconductionconvectionradiation
- 17. Multiple ChoiceWarm air over the beach rises while cooler, dense air from the ocean rushes in due toconductionconvectionradiation
- 18. Multiple ChoiceThe metal skewer gets so hot that you drop your marshmallow into the campfire because ofconductionconvectionradiation
- 19. Multiple Choice
A student touches her finger to a metal sink and notices her finger is left feeling cold. Which of the following statements correctly explains this observation?
Heat flows from the students finger to the sink by the process of conduction
Cold flows from the students finger to the sink by the process of conduction
heat flows from the students finger to the sink by the process of radiation
Heat flows from the students finger to the sink by the process of convection

- 21. Multiple Choice
The heater in the room shown in the picture is continuously warming the air around it so that the air near the heater is much warmer than the air in the rest of the room. What happens to the air around the heater as it is warmed?
It rises toward the ceiling, but it does not stay there or move toward the walls. Instead, it sinks back down to the floor.
It moves away from the heater in all directions until it fills the room
It rises toward the ceiling and stays there
It rises toward the ceiling, but does not stay there. It moves toward the walls before it eventually sinks back down to the floor.
- 22. Multiple Choice
As the warm air moves from one side of the room to the other, does the amount of thermal energy at the other side of the room increase?
No, because air in one place in the room has the same amount of thermal energy as an equal amount of air anywhere else in the room
Yes, because the warm air near the fire had more thermal energy than the colder air that was across the room
It depends on how warm the air is because only air can carry thermal energy as it moves
No, because air cannot carry thermal energy as it moves
- 23. Multiple Choice
The sun heats the surface of the ocean's water by radiation. The water heats up and becomes warm. The water then heats up the air by which thermal energy transfer?
Convection
Radiation
Conduction
Evaporation
- 24. Multiple Choice
What causes the circulation of air in the atmosphere?
Air in the atmosphere is heated by the sun and sinks to the ground by convection
The ground is heated by the sun by radiation and then the ground heats the air by conduction, causing the air to rise. The cool air at the top then sinks, creating a convection current.
Air loses heat to the ground and then rises upward to obtain more energy creating a convection current
The sun heats the clouds which forces the cooler air to move away and sink by convection
- 25. Multiple ChoiceIn this experiment, the WARM red dye and the COLD blue dye was placed in the water at the same time. The warm red dye rose to the top while the cold blue dye sank to the bottom.conductionconvectionradiation
