Exploring Heat

What is heat transfer?

• Heat transfer is the process of energy moving from a cooler object to a warmer object.

• Heat transfer is the process of energy moving from one object to another without any temperature change.

• Heat transfer is the process of energy moving from a warmer object to a cooler object.

Name two sources of heat.

• Fire and the sun

• Electricity and magnets

• Ice and snow

• Water and wind

Explain how heat flows from a hot object to a cold object.

• Heat flows from a hot object to a cold object based on the weight of the objects.

• Heat flows from a hot object to a cold object because of the color of the objects.

• Due to the temperature difference between the two objects, heat energy transfers from the hotter object to the colder object.

Give an example of a good conductor of heat.

• Fabric

• Rubber

• Plastic

• Copper

Give an example of a poor conductor of heat.

• Aluminium

• Iron

• Steel

• Wood

How is temperature related to heat?

• Temperature and heat are the same thing.

• Temperature is a measure how hot an object is, while heat is the amount of energy an object has.

• Temperature is a measure of the energy in a substance, while heat is the measure of the speed of particles.

What does a thermometer measure?

• Mass

• Volume

• Temperature

Why do metals feel cold to the touch in a cold room?

• Metals absorb heat from the environment

• Metals are good conductors of heat and allows heat to flow from our skin quickly.

• Metals have a natural cooling effect
