Heat Transferring

What are four forms of energy?

• electrical, kinetic, potential, light

• sound, thermal, light, chemical

• potential, chemical, electrical, sound

• light, thermal, potential, kinetic

Light energy is a type of energy that is carried by...

• water.

• food.

• waves.

• people.

This is stored in links between atoms and molecules...

• potential energy.

• nuclear energy.

• light energy.

• chemical energy.

An example of thermal energy is...

• molecules, atoms, heater

• heater, stove, fire

• oven, water, sun

• atoms, battery, lamp

Thermal energy moves from an object with a higher temperature to an

• object with a higher temperature

• object with a lower temperature

• object with a moving temperature

• object with no temperature

When one temperature block is cold and another block is hot, what will happen when the two meet together?

• The cold block will transfer some of its energy into the hot block

• The hot block will transfer some its energy into the other block.

• The hot block will transfer some its thermal energy into the cold block which will raise its temperature until both blocks reach the same temperature.

• Nothing will happen and both block will remain the same temperature.

How many ways can heat can transfer?

• one

• six

• three

• zero

What is conduction?

• particles linking with solids, liquids, gases

• heat transferring from vibrating particles

• the transferring of matter

• a pot of boiling water

What is convection?

• Convection is heat transferring through a liquid or a gas.

• Convection is heat transferring into a solid.

• Convection is heat transferring into you hand.

• Convection is heat transferring into wood.

True or False: Convection occurs in gases and liquids only.

• True

• False
