S8P1 and S8P2 Review - Fall 2022

Front

What type of heat transfer is demonstrated when warm air rises and cool air sinks?

Back

Convection

Front

What is a characteristic of a substance that can be observed without changing it chemically?

Back

Physical property

Front

Fill in the blank: Between ball B and Ball C, ball __________ has LESS potential energy because ____________.

Back

B; its mass is smaller

Front

At which point is potential energy greatest in a given system?

Back

Point W

Front

What kind of energy is stored in a stretched rubber band?

Back

Potential energy

Front

Define convection in the context of heat transfer.

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What are some examples of physical properties of a substance?

Back

Size, shape, density, phase (solid, liquid, gas).

Front

How does mass affect potential energy?

Back

Potential energy is directly proportional to mass; as mass increases, potential energy increases.

Front

What is the formula for calculating gravitational potential energy?

Back

Gravitational potential energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

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.
