Heat Transfer Methods

Define convection.

• The transfer of heat in a liquid or gas, where warmer parts rise and cooler parts sink.

• The process of heat transfer through direct contact between materials.

• The movement of air caused by temperature differences in the atmosphere.

• The transfer of heat through electromagnetic waves.

Give an example of radiation.

• The warmth felt from the sun on your skin.

• The sound of a ringing bell.

• The taste of salt in seawater.

• The color of a rainbow.

What are the three main methods of heat transfer?

• Conduction, Convection, and Radiation

• Conduction, Convection, and Insulation

• Conduction, Radiation, and Absorption

• Convection, Radiation, and Reflection

What happens to particles in a gas when heated?

• They move faster and spread apart.

• They move faster and spread apart.

• They remain stationary and unchanged.

• They condense into a liquid.

Give an example of convection.

• The movement of water in a boiling pot.

• The process of photosynthesis in plants.

• The formation of clouds in the sky.

• The freezing of water into ice.

Define radiation.

• The transfer of heat by invisible waves

• The process of converting light into energy

• The movement of particles in a solid

• The emission of sound waves through air

Give an example of conduction.

• A metal spoon getting hot when placed in a hot soup.

• A fan blowing air to cool a room.

• Ice melting in a warm drink.

• A pot heating on a stove.

What is heat transfer?

• The movement of thermal energy from a hotter object to a colder object.

• The process of converting thermal energy into mechanical energy.

• The transfer of energy through electromagnetic waves.

• The circulation of air in a closed environment.

What is thermal energy?

• The energy produced by heating an object.

• The energy stored in chemical bonds.

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

• The energy associated with the motion of an object.

Define conduction.

• The transfer of heat through direct contact between materials.

• The movement of heat through fluids due to density differences.

• The process of heat transfer through electromagnetic waves.

• The transfer of heat through the movement of particles in a gas.
