ELL Test Heat Transfer & Transformations

Front

What happens to the kinetic energy of atoms when heat is applied?

Back

The kinetic energy of atoms increases, causing them to move more rapidly.

Front

What types of energy does a television transform electrical energy into?

Back

Light, thermal, and sound energy.

Front

What is the correct order of energy transformations in photosynthesis?

Back

Light energy is transformed into chemical energy.

Front

What is the energy transformation that occurs when a violin is played?

Back

Mechanical energy is transformed into sound energy.

Front

What happens to particle motion when the temperature of a system increases?

Back

The particles move more quickly.

Front

Define heat transfer.

Back

Heat transfer is the movement of thermal energy from one object or substance to another.

Front

What are the three methods of heat transfer?

Back

Conduction, convection, and radiation.

Front

Explain conduction.

Back

Conduction is the transfer of heat through direct contact between materials.

Front

Explain convection.

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

Explain radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves.
