Heat & Temperature

What is radiation?

• A method of transferring heat through direct contact

• The transfer of heat in the form of electromagnetic waves, such as light

• A process that requires a medium to travel through

• A type of sound wave that travels through air

What is an example of convection?

• Warm air rising near a heater, causing cooler air to move in and create a circulation.

• Ice melting in a glass of water.

• Water boiling in a pot on the stove.

• A leaf falling from a tree in autumn.

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 conduction?

• The transfer of heat through direct contact between materials.

• The movement of air in a convection current.

• The process of heat being absorbed by a material without direct contact.

• The conversion of heat energy into mechanical energy.

What is temperature?

• A measure of the average kinetic energy of the particles in an object.

• The amount of heat energy in an object.

• The total mass of an object divided by its volume.

• A measure of how much an object weighs.

What is thermal energy?

• The energy stored in chemical bonds of molecules.

• The total kinetic energy of all the particles in an object.

• The energy associated with the motion of an object.

• The energy released during a nuclear reaction.

What happens to air when it is heated?

• It contracts and becomes denser.

• It expands, becomes less dense, and rises.

• It remains the same regardless of temperature.

• It cools down and sinks.

What is an example of radiation?

• Feeling warmth from the sun or a fireplace without direct contact.

• The sound of a bell ringing in the distance.

• The smell of freshly baked bread.

• The sight of a rainbow after rain.

What is the difference between heat and temperature?

• Heat is the energy transferred between objects due to a temperature difference, while temperature is a measure of the average kinetic energy of particles.

• Heat is a measure of the average kinetic energy of particles, while temperature is the energy transferred between objects.

• Heat and temperature are the same concepts and can be used interchangeably.

• Heat is the energy stored in an object, while temperature is the energy lost by an object.

What is an example of conduction?

• Touching a hot stove and feeling the heat transfer to your hand.

• Boiling water in a pot on the stove.

• Feeling the warmth of the sun on your skin.

• Using a microwave to heat food.
