1. Question

The first law of thermodynamics states

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

Correct Incorrect Correct answer

Energy can be created or destroyed, it can only be changed or transformed from one form to another.

Correct Incorrect Correct answer

Energy cannot be created or destroyed, it can only be changed or transformed into only one form.

Correct Incorrect Correct answer

Energy can be created or destroyed, it can be changed or transformed from one form to another.

Correct Incorrect Correct answer

Question 2 of 14

2. Question

How does the following diagram demonstrate the first law of thermodynamics?

The amount of entropy is decreasing as we move up each trophic level.

Correct Incorrect Correct answer

Energy is being created and destroyed as we move up trophic levels.

Correct Incorrect Correct answer

The amount of entropy is increasing as we move up each trophic level.

Correct Incorrect Correct answer

Energy is not being created or destroyed, it's just being transferred as we move up trophic levels.

Correct Incorrect Correct answer

Question 4 of 14

4. Question

How is the second law of thermodynamics demonstrated in the following diagram?

as we move up the trophic levels more and more energy is lost as metabolic heat to power bodily functions which leads to more entropy or disorder in the system.

Correct Incorrect Correct answer

as we move up the trophic levels more and more energy is lost as metabolic heat to power bodily functions which leads to less entropy or disorder in the system.

Correct Incorrect Correct answer

as we move down the trophic levels more and more energy is lost as metabolic heat to power bodily functions which leads to more entropy or disorder in the system.

Correct Incorrect Correct answer

as we move up the trophic levels less and less energy is lost as metabolic heat to power bodily functions which leads to more entropy or disorder in the system.

Correct Incorrect Correct answer

Question 7 of 14

7. Question

If energy cannot be created or destroyed and is transferred from one form to another, then why do they say we have an energy crisis?

We are losing matter on the planet, and we cannot get this matter back.

Correct Incorrect Correct answer

We are gaining more and more energy in the form of heat, and we can reuse the heat to produce more energy.

Correct Incorrect Correct answer

There is too much energy on the planet which may lead to an over explosion of energy.

Correct Incorrect Correct answer

We are losing more and more energy in the form of heat, and we cannot reuse the heat to produce more energy.

Correct Incorrect Correct answer

Question 8 of 14

8. Question

As the amount of energy transfers increase…

the amount of entropy in the universe increases

Correct Incorrect Correct answer

the amount of entropy in the universe decreases

Correct Incorrect Correct answer

the amount of entropy in the universe stabilizes

Correct Incorrect Correct answer

the amount of entropy in the universe stabilizes and then lowers

Correct Incorrect Correct answer

Question 9 of 14

9. Question

Which law of thermodynamics does the following picture BEST demonstrate? Explain why.

The first law of thermodynamics because the entropy is increasing as the cow performs bodily functions

Correct Incorrect Correct answer

The first law of thermodynamics because it shows energy being transformed from one form to another.

Correct Incorrect Correct answer

The second law of thermodynamics because the entropy is increasing as the cow performs bodily functions

Correct Incorrect Correct answer

The second law of thermodynamics because it shows energy being transformed from one form to another.

Correct Incorrect Correct answer

Question 10 of 14

10. Question

The second law of thermodynamics states that

the entropy or disorder of an isolated system will always decrease until it reaches a minimum level.

Correct Incorrect Correct answer

energy cannot be created or destroyed, it can only be changed or transformed from one form to another.

Correct Incorrect Correct answer

the entropy or disorder of an isolated system will always increase until it reaches a maximum level.

Correct Incorrect Correct answer

energy can be created or destroyed, it can only be changed or transformed from one form to another.

Correct Incorrect Correct answer

Question 11 of 14

11. Question

Why is it that no energy transfer is 100% efficient?

Energy is always gained in the form of heat.

Correct Incorrect Correct answer

Energy is always gained in the form of radiation.

Correct Incorrect Correct answer

Energy is always gained in the form of air currents.

Correct Incorrect Correct answer

Energy is always lost in the form of heat.
