Question

practice 1
drag and drop the descriptions and images to the correct type of energy movement.
conduction
convection
radiation
no direct contact; energy travels in electromagnetic waves
visible light is an example
heat travels from object to object through direct contact.
steam escapes from a pot of hot water and flows upward.
heat from hot tea transfers to the tea cup, which transfers to the hands
light from a tablet shines on the faces of a mother and daughter.
heat travels through fluids by causing hot particles to rise and cool to sink.
a pot of water gets hot from the stove which allows the heat to move from the stove to the pot to the water.
holding your hand over a flame, you can feel the heat from the hot air rising.

Explanation:

• Conduction: Defined as heat transfer through direct physical contact between objects or substances.
• Convection: Heat transfer in fluids (liquids/gases) via movement of hot, less dense particles rising and cool, denser particles sinking.
• Radiation: Energy transfer through electromagnetic waves, requiring no direct contact or medium.

Answer:

Conduction

• Heat travels from object to object through direct contact.
• Heat from hot tea transfers to the tea cup, which transfers to the hands
• A pot of water gets hot from the stove which allows the heat to move from the stove to the pot to the water.

Convection

• Steam escapes from a pot of hot water and flows upward.
• Heat travels through fluids by causing hot particles to rise and cool to sink.
• Holding your hand over a flame, you can feel the heat from the hot air rising.

Radiation

• No direct contact; energy travels in electromagnetic waves
• Visible light is an example
• Light from a tablet shines on the faces of a mother and daughter.
