Fall Final Exam NGSS Chemistry

Front

What happens to the volume of a gas in a balloon when the temperature increases, assuming pressure is constant?

Back

The volume of the gas increases (the balloon expands).

Front

What is the term for energy that travels across distances in the form of electromagnetic waves?

Back

Radiation.

Front

What is an example of energy conversion from light energy to chemical energy?

Back

Growing an apple tree.

Front

Which type of crust is denser: oceanic or continental?

Back

Oceanic crust is more dense than continental crust.

Front

Where is maximum potential energy located on a roller coaster?

Back

At the top of a big hill.

Front

What is the relationship between temperature and volume of a gas at constant pressure?

Back

As temperature increases, volume increases (Charles's Law).

Front

What is conduction?

Back

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

Front

What is convection?

Back

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

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is the energy of motion.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.
