Conduction
Conduction mainly occurs in what type of material?
Solids (especially metals)
Convection happens in which states of matter?
Liquids and gases
Radiation transfers heat through what?
Heat moves as invisible rays or waves
What type of heat transfer warms soup in a pot on a stove?
Heat moving in liquids or gases, like boiling water
Which type of heat transfer works in solids, liquids, and gases?
Heat moving through waves, which works in solids, liquids, or air
During conduction, how do particles pass heat from one part of a solid to another?
Heat moves from the hot part to the cooler part
What causes convection currents?
Hotter parts move up and cooler parts move down, creating a flow
Does radiation require a medium?
No medium is needed; heat can travel through empty space
When your hand touches a hot pan handle, what type of heat transfer is it?
Heat passing directly through something, like a pan handle
Which type of heat transfer needs direct contact?
Heat moving by direct contact
Why is metal a good conductor?
Metals carry heat faster than most other materials
Why does hot air rise?
Hot air rises because it is lighter than cold air
What type of radiation from the sun warms the Earth?
Heat from the Sun or other warm objects
Why does wearing black clothes on a hot day feel warmer?
Black or dark objects feel hotter in the sun
Which type of heat transfer is responsible for ocean currents?
Heat moving in liquids or gases, like ocean currents
What happens to heat in a solid during conduction?
The heat spreads from the hot area to the cooler area
Name one natural convection example.
Warm water or air moving upward and cooler parts moving down
Which absorbs more heat: dark or light surfaces?
Dark surfaces absorb heat better than light surfaces
How does a campfire warm people sitting nearby?
Heat from a fire warming you up
If the sun suddenly stopped shining, which type of heat transfer would disappear first on Earth?
If the Sun stopped, Earth would stop getting heat through space
Give one example of conduction from daily life.
A spoon getting hot in a pot of soup (Any other example is acceptable if it matches the question asked)
What is needed for convection that conduction and radiation don’t require?
A liquid or gas needs to move for convection to happen
Give an example of radiation from daily life.
The Sun’s heat warming the Earth
What heat transfer happens inside an oven without a fan?
Oven heat spreading without touching the food
Which heat transfer explains why the Earth doesn’t freeze despite space being a vacuum?
Sunlight keeps Earth warm even though space is empty
