• Frozen ice cream
• Liquid Ice cream

In which of the following systems is entropy increasing?

• Putting together a puzzle
• Putting books on a shelf
• Breaking a plate

The Law of Conservation of Energy states:

• Energy can created or destroyed but not transformed 
• Energy cannot be created or destroyed, it can only transformed
• Energy can't be created, destroyed or transformed

The 2nd Law of Thermodynamics tells us...

• Heat flows from cold to hot.

• Heat flows randomly, it's a 50/50 coin flip

• Heat doesn't flow, temperature flows.

• Heat flows from hot to cold.

Alice takes an ice tray filled with ice out of the freezer. As the ice melts, what happens to its entropy?

• entropy increases
• entropy decreases
• entropy remains constant

Which will have the greatest entropy: ice, water, or water vapor? 

• ice
• water
• water vapor

An object with the lowest entropy level will have the lowest or highest temperature?

• lowest
• highest

Given the change of phase:

CO₂(g) —> CO₂(s)

As CO₂(g) changes to CO₂(s), the entropy of the system

• decreases

• increases

• remains the same
