Review for Energy Test

Front

What is the boiling point of a substance as shown in a heating curve graph?

Back

The boiling point is the temperature at which a substance changes from a liquid to a gas. For the given substance, the boiling point is 218°C.

Front

What unintended consequence should be analyzed before constructing a nuclear power plant at an ocean site?

Back

The effect of warmed water on aquatic life.

Front

What is the process of converting potential energy into kinetic energy?

Back

Potential energy is converted into kinetic energy when an object moves from a higher position to a lower position, such as from point A to point B.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which carbon dioxide and water are converted into glucose (sugar) by plants, algae, and certain bacteria using sunlight energy.

Front

What energy transformations occur in a pencil sharpener plugged into a wall outlet?

Back

Electrical energy is transformed into mechanical energy, which is then transformed into sound energy.

Front

What is kinetic energy?

Back

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, such as an object held at a height.

Front

Explain the concept of energy conservation.

Back

Energy conservation refers to the principle that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy required for plants to convert carbon dioxide and water into glucose and oxygen.

Front

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally (e.g., solar, wind), while non-renewable sources (e.g., coal, oil) are finite and will eventually deplete.
