Lesson 4-2 Review

The transfer of energy from one particle of matter to another within an object or between objects that are in direct contact is

• conduction
• convection
• radiation

A type of heat transfer that occurs through the movement of fluids, which can be solid,liquid, or gas is

• conduction
• convection
• radiation

The transfer of energy by electromagnetic waves is

• conduction
• convection
• radiation

A circular motion in air that causes wind and changes in the weather is

• conduction
• convection currents
• radiation

Heat is transferred from warmer areas to cooler areas by

• Currents, weather, and atmosphere.
• Electrical energy, mechanical energy, and thermal energy.
• Conduction, convection, and radiation.
• Temperature, Farenheit, and Celsius.

What happens when air is heated?

• The sun transfers energy to Earth.
• Its particles speed up and move farther apart making it less dense.
• Heat transfers in random directions.
• Sunlight travels through empty space.

Which form of heat transfer does not involve matter?

• Conduction
• Convection
• Radiation
• Thermal energy

What happens to the energy in a system?

• It is conserved.
• It is transformed.
• It is transferred.
• It is destroyed.

By the law of conservation, energy cannot be created or destroyed.

• True
• False
