Heat and Heat Transfer

This type of heat transfer takes place with direct contact and at least one solid object. Example a burner on a stove heating the bottom of a pot.

• convection

• radiation

• conduction

Heat is transferred from the sun to Earth by which kind of heat transfer

• convection

• radiation

• conduction

The air is warmer near the ceiling of a room. The warm air rises because of ____________.

• convection

• radiation

• conduction

The heat from a lamp allows a lizard to remain warm. This is an example of which type of heat transfer?

• convection

• radiation

• conduction

You hold a solid chocolate bar in your hand, which then starts to warm up and soften. This happens due to what?

• convection

• radiation

• conduction

The kind of heat transfer that travels through space in electromagnetic waves is

• convection

• radiation

• conduction

In heat transfer, heat always flows from the _________ substance to the ____________ substance.

• hotter to colder

• colder to hotter

In which direction will the heat flow while a person holds a cup of hot tea. (The cup is hotter than the person's hand.)

• from hand to cup

• from cup to hand

• no heat will be transferred

What type of heat transfer is happening here?

• The pot sitting on the burner is conduction and the water in the pot is convection

• The pot sitting on the burner is convection and the water in the pot is conduction

• The pot sitting on the burner is radiation and the water in the pot is convection

• The pot sitting on the burner is conduction and the water in the pot is radiation

This sunbather is getting a warm because ______

• The heat from the sun is travelling through electromagnetic waves and conduction is occurring.

• The heat from the sun is travelling through electromagnetic waves and radiation is occurring.

• The heat from the sun is travelling through electromagnetic waves and convection is occurring.

• the sun is transferring energy
