Question

a.) match up the heat transfer method with its definition. all three must be correct to receive credit.transfer of heat through buoyant mixing.transfer of heat through electomagnetic radiation (light).transfer of heat through direct contact.b.) for the following situations, select the heat transfer method that is being used. all three must be correct to receive credit.a person in a tanning beda hot pad on a persons backthe liquid in a lava lamp

Explanation:

Part a)

• Transfer of heat through buoyant mixing: This is the definition of convection. Convection involves the movement of fluid (liquid or gas) due to density differences caused by temperature variations, leading to buoyant mixing and heat transfer.
• Transfer of heat through electromagnetic radiation (light): This is the definition of radiation. Radiation does not require a medium and transfers heat via electromagnetic waves, like light.
• Transfer of heat through direct contact: This is the definition of conduction. Conduction occurs when heat is transferred between objects in direct contact, through molecular collisions.

• A person in a tanning bed: Tanning beds use UV light (electromagnetic radiation) to transfer heat/energy to the skin, so this is radiation.
• A hot pad on a person's back: The hot pad is in direct contact with the back, transferring heat through molecular contact, so this is conduction.
• The liquid in a lava lamp: The liquid (and wax) moves due to temperature differences (buoyant mixing) as it heats and cools, so this is convection.

Answer:

(for matching):

• Transfer of heat through buoyant mixing: Convection
• Transfer of heat through electromagnetic radiation (light): Radiation
• Transfer of heat through direct contact: Conduction
