Heat

Whai is heat? Give the scientific answer.

• It's a form of electrical energy.

• It's its own form of energy.

• It's a form of mechanical energy.

• It's when things are warm.

What is the way we measure heat energy?

• Temperature

• Length

• Mass

• Time

What's the tool we use to measure temperature?

• Balance

• Meter tape.

• Dynamometer

• Thermometer

If you touch a metal bar that is warmer than your hands...

• ... heat stays where it is.

• ... heat moves from the bar to your hands.

• ... heat dissolves

• ... heat moves from your hands to the bar

If you touch a metal bar that is colder than your hands...

• ... heat stays where it is.

• ... heat moves from the bar to your hands.

• ... heat dissolves

• ... heat moves from your hands to the bar

How do you produce friction?

• When you switch on an object with a switch.

• When you rub two objects together.

• When you place two objects so that they touch.

• When you use those frixion pens.

What does fraction do?

• It changes heat energy into motion energy.

• It changes heat energy into electric energy.

• It changes motion energy into heat energy.

• It changes heat energy into motion energy.

How can you increase the amount of heat you produce? (Tick all that applies)

• You can light up a fire in the fireplace.

• You can rub the objects faster.

• You can rub at the objects slower.

• You can press the objects harder as you rub them.

What are other ways of producing heat energy? (Tick all that applies)

• You can change chemical energy into heat energy, for example when you burn a piece of wood.

• You can change electrical energy into heat energy, for example a light bulb becomes hotter when it produces light.

• You can change heat energy into other kinds of heat energy.

• You can change heat energy into chemical energy, for example when you burn a piece of wood.
