Question

practice it! select the statement(s) that are true about the transfer of thermal energy. when thermal energy transfers, the warmer particles cause cooler particles to slow down. convection is used to make hard - boiled eggs in a pot of water on a stove. burning your hand by touching a hot plate is an example of thermal energy transfer by conduction. warmth can be felt near a campfire because electromagnetic waves are emitted from the flames. fire gives off electromagnetic waves in the form of microwaves and gamma rays.

Explanation:

1. Analyze the first statement: When thermal energy transfers, warmer particles transfer energy to cooler ones, making cooler particles move faster (not slow down), so this is false.
2. Analyze the second statement: In a pot of water, heat transfer from the stove to water and then to eggs occurs via convection (movement of fluid), so this is true.
3. Analyze the third statement: Touching a hot plate transfers heat through direct contact (conduction), so this is true.
4. Analyze the fourth statement: Campfire warmth is from infrared (electromagnetic) waves emitted, so this is true.
5. Analyze the fifth statement: Fire emits infrared, visible light, etc., not microwaves (used in ovens) or gamma rays (high - energy, from nuclear processes), so this is false.

Answer:

B. Convection is used to make hard - boiled eggs in a pot of water on a stove.
C. Burning your hand by touching a hot plate is an example of thermal energy transfer by conduction.
D. Warmth can be felt near a campfire because electromagnetic waves are emitted from the flames.
