Energy Transfer Remediation

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one system or object to another, often occurring in the form of heat, work, or radiation.

Front

What are the three main types of heat transfer?

Back

The three main types of heat transfer are conduction, convection, and radiation.

Front

Define conduction.

Back

Conduction is the transfer of heat through direct contact between materials, where energy is passed from one molecule to another.

Front

Define convection.

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warmer areas of a fluid rise and cooler areas sink.

Front

Define radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, which can occur in a vacuum.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often related to height in a gravitational field.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and velocity.

Front

Explain the energy transformation when a child slides down a slide.

Back

As the child descends, potential energy is converted into kinetic energy, increasing their speed.

Front

What happens to warm air in convection?

Back

Warm air rises because it is less dense than cooler air, which then sinks, creating a convection current.

Front

How does touching a hot object result in conduction?

Back

When you touch a hot object, heat is transferred directly from the object to your skin through molecular contact.
