Laws of Thermodynamics quiz Flashcards

The first law of thermodynamics states that energy cannot be created or destroyed, only transferred and transformed.

Entropy is the measure of disorder or randomness in a system.

A tidy room would have less entropy compared to a messy room.

No, energy cannot be destroyed; it can only be transferred and transformed.

The second law of thermodynamics states that energy transfer is not 100% efficient, and some energy is lost to the environment, often as heat.

Not all energy is transferred from producer to consumer because some energy is lost as heat, according to the second law of thermodynamics.

The principle of conservation of energy states that energy cannot be created or destroyed, only transferred and transformed.

The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time.

Energy that is not transferred efficiently in a food chain is often lost as heat.

The 10% rule states that only about 10% of the energy is transferred from one trophic level to the next in an ecosystem.

No, energy cannot be created according to the first law of thermodynamics.

Temperature is an example of an abiotic factor that can affect entropy in a system.

The second law of thermodynamics explains why energy decreases at each successive trophic level in an energy pyramid due to energy loss as heat.

Entropy is directly related to the disorder of a system; higher entropy means more disorder.

It is known as the principle of conservation of energy because it states that energy cannot be created or destroyed, only transferred and transformed.
