Chapter 5 Parts 1, 2, & 3

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer areas of a liquid or gas rise and cooler areas sink, creating a circulation pattern.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through, allowing heat to be transferred through a vacuum.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What are exothermic reactions?

Back

Exothermic reactions are chemical reactions that release energy, usually in the form of heat, to the surroundings.

Front

What are endothermic reactions?

Back

Endothermic reactions are chemical reactions that absorb energy from the surroundings, resulting in a decrease in temperature.

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the molecules in a substance. It indicates how hot or cold a substance is.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat is transferred from the hotter part of an object to the cooler part.

Front

What is the difference between heat and temperature?

Back

Heat is the total energy of molecular motion in a substance, while temperature is a measure of the average kinetic energy of the molecules.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.

Front

What is an example of convection?

Back

An example of convection is the circulation of warm air in a room heated by a radiator.
