G6 U2: Energy Review

Heat is a form of energy transfer that always moves from:

• Cold to hot

• Hot to cold

• Warm to warmer

• High to low pressure

Convection occurs when heat moves in a circular motion due to:

• Radiation of light

• Warm air falling and cold air rising

• Warm air rising and cold air sinking

• Air condensing on a surface

Conduction occurs when heat is transferred through:

• Waves

• Circular motion

• Touch

• Light

Radiation occurs when heat is transferred through:

• Direct contact

• Liquids

• Waves

• Gases only

Kinetic energy is energy of:

• Stored potential

• Movement

• Heat

• Position

Potential energy is:

• Energy in motion

• Lost energy

• Stored energy

• Electrical energy

What is the Law of Conservation of Energy?

• States that energy is only created through motion

• States that energy can be created by friction

• States that energy can not be created or destroyed

• States that energy is always lost as heat

What energy transformation occurs when you turn on a battery-powered radio?

• Electrical to light

• Chemical to sound

• Nuclear to mechanical

• Mechanical to chemical

What energy transformation occurs at a nuclear power plant?

• Electrical to nuclear

• Nuclear to electrical

• Thermal to sound

• Solar to chemical

What type of heat transfer occurs when an air conditioner circulates air?

• Radiation

• Conduction

• Convection

• Evaporation
