Show hintHide hint
Think of the scale of temperatures.
Question 2.
How does the kinetic energy of particles behave at absolute zero?
Show hintHide hint
Remember, no motion means no kinetic energy.
3Question 3.

Show hintHide hint
Think about the definition of absolute zero.
Question 5.
If the entropy of a perfect crystal is 0 at absolute zero, and it increases as temperature rises, describe what happens to the crystal's structure as it warms.
Show hintHide hint
Consider how heat affects molecular motion and arrangement.
Question 6.
