Twig Module 2 Review Energy

Front

What covering will cause ice cubes to melt the least when placed in bright sunshine?

Back

A white plastic covering reflects sunlight and minimizes heat absorption, causing the ice cubes to melt the least.

Front

Are fossil fuels a renewable source of energy?

Back

No, fossil fuels are not renewable; they are finite resources formed over millions of years.

Front

What energy resource does a helicopter primarily use?

Back

A helicopter primarily uses gas (aviation fuel) as its energy resource.

Front

Does energy stay in one object forever?

Back

No, energy can transfer between objects and change forms; it does not stay in one object forever.

Front

Can light and heat from the Sun turn into electricity on their own?

Back

No, light and heat from the Sun require technology (like solar panels) to convert into electricity.

Front

What is the definition of renewable energy?

Back

Renewable energy is energy that is collected from resources that are naturally replenished, such as sunlight, wind, and water.

Front

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

Back

Renewable energy sources can be replenished naturally in a short period, while non-renewable sources, like fossil fuels, take millions of years to form and are finite.

Front

What is the role of solar panels in energy conversion?

Back

Solar panels convert sunlight into electricity through the photovoltaic effect.

Front

What are some examples of non-renewable energy sources?

Back

Examples of non-renewable energy sources include coal, oil, natural gas, and nuclear energy.

Front

How does the color of a covering affect heat absorption?

Back

Darker colors absorb more heat, while lighter colors reflect more sunlight, affecting the temperature of objects beneath them.
