Understanding the Third Law of Thermodynamics

What does the third law of thermodynamics state about entropy as temperature approaches absolute zero?

• Entropy becomes negative.

• Entropy approaches a constant minimum.

• Entropy remains unchanged.

• Entropy becomes infinite.

How is entropy illustrated using a bottle of carbonated drink?

• By showing the drink freezing.

• By observing the drink evaporate.

• By shaking the bottle to form bubbles.

• By heating the drink to boil.

What is specific heat capacity?

• The energy needed to cool a substance to absolute zero.

• The energy required to change the state of a substance.

• The energy needed to raise the temperature of one kilogram of a substance by one Kelvin.

• The energy required to melt a substance.

Why does it take more time to warm a wooden glass compared to an aluminum glass?

• Wood is a better conductor than aluminum.

• Wood has a higher specific heat capacity than aluminum.

• Aluminum is a better conductor than wood.

• Aluminum has a higher specific heat capacity than wood.

What unique property does spin ice exhibit at absolute zero?

• It becomes a perfect insulator.

• It loses all magnetic properties.

• Its atomic magnetic moments remain random.

• It becomes a superconductor.
