Topic 3 Test Review: Thermal Energy - Key Concepts

Temperature is total energy of all particle motion

Temperature measures total heat inside an object

Thermal energy is average kinetic energy of particles

Thermal energy is total particle motion energy

Heat moves from cooler soup to warmer spoon naturally

Heat does not move because temperatures are different

Heat moves from spoon to soup because spoon is cooler

Heat moves from soup to spoon because soup is warmer

Particles move faster with more kinetic energy

Particles move slower with less kinetic energy

Particles stop moving with no kinetic energy

Particles change to solids due to less motion

Solid has greatest particle kinetic energy

Gas has greatest particle kinetic energy

All states have equal particle kinetic energy

Liquid has greatest particle kinetic energy

Metal spoon heating while touching hot soup

Hand warming near a campfire flame

Warm air rising to the upstairs level

Feeling sunlight on your face outdoors

Convection in moving air currents

Radiation from interior walls

Conduction between floor materials

Evaporation of indoor moisture

Conduction through skin and air

Absorption through chemical reactions

Convection in atmospheric winds

Radiation via electromagnetic waves

Radiation from body to ice

Conduction from warmer skin

Convection in surrounding air

Evaporation of liquid water

Condensation inside the bag

Radiation from microwaves

Convection of circulating air

Conduction from metal rack

It cools as convection removes energy

It stays cool because radiation is weak

It warms as heat conducts through metal

It heats only when light shines on it
