What is radiation?
The transfer of energy through electromagnetic waves, which can occur in a vacuum.
The process of heat transfer through direct contact.
The emission of particles from a radioactive substance.
The movement of air in the atmosphere.
How does heat move?
From the cooler thing to the warmer thing.
From the warmer thing to the cooler thing.
Heat does not move; it stays in one place.
Heat moves randomly without direction.
What is the definition of conduction?
The transfer of heat through direct contact between materials.
The movement of heat through fluids without direct contact.
The process of heat being absorbed by a material without transfer.
The circulation of air that causes temperature changes.
What is an example of convection?
Warm air rising and cool air sinking in a room.
Water boiling in a pot on the stove.
Ice melting in a glass of warm water.
A fan blowing air across a room.
Which does NOT require a solid, liquid, or gas to travel through?
Sound
Water waves
Radiation
Air waves
Conduction is the movement of heat molecules because of the collision of ______.
Atoms
Molecules
Electrons
Ions
What is thermal equilibrium?
The state in which two objects in contact with each other reach the same temperature.
The condition where heat is continuously transferred between two objects.
The process of heating an object until it melts.
The temperature at which a substance changes from solid to liquid.
What is convection?
The transfer of heat through the movement of fluids (liquids or gases).
The process of heat transfer through direct contact between materials.
The transfer of heat through electromagnetic waves.
The movement of air caused by temperature differences.
What is the relationship between temperature and kinetic energy?
As temperature increases, the kinetic energy of the particles increases.
Temperature has no effect on kinetic energy.
Kinetic energy decreases as temperature increases.
Kinetic energy is independent of temperature.
What is the kinetic theory of matter?
A theory that states that all matter is made up of particles that are in constant motion.
A theory that explains the behavior of gases in terms of temperature and pressure.
A theory that describes the chemical reactions between different types of matter.
A theory that states that matter can exist in three different states: solid, liquid, and gas.
What happens to the temperature of a substance when it absorbs heat?
The temperature decreases.
The temperature remains the same.
The temperature increases.
The temperature fluctuates.
What is an example of conduction?
A metal spoon getting hot when placed in a hot pot of soup.
A fan blowing air to cool a room.
Boiling water in a kettle on the stove.
Ice melting in a warm room.
According to the kinetic theory, what happens when ice (a solid) melts into liquid water?
The water molecules gain heat energy.
The water molecules lose heat energy.
The water molecules become more rigid.
The water molecules move slower than in solid form.
What is an example of radiation?
Feeling the warmth of the sun on your skin.
Hearing a sound from a distance.
Seeing a rainbow after rain.
Tasting salt in the ocean.
True or false? Energy can change forms.
True
False
Sometimes
Never
