7th Grade Unit 1 Flashcard

Front

What happens to the kinetic energy of particles as temperature decreases?

Back

Kinetic energy decreases because particles move slower.

Front

Which container allows the most heat to escape from water to the environment?

Back

Container S.

Front

What process allows heat to travel from a hot metal spoon to your hand through direct contact?

Back

Conduction.

Front

What method of heat transfer allows warmth from the Sun to reach you in space?

Back

Radiation.

Front

How many molecules of water (H2O) are present if the coefficient is 2?

Back

2.

Front

Define kinetic energy.

Back

The energy that an object possesses due to its motion.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

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

Front

What is radiation?

Back

The transfer of heat in the form of electromagnetic waves.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, kinetic energy increases because particles move faster.
