About This Quiz & Worksheet

The questions on this quiz will primarily deal with the definition and characteristics of entropy. Some questions ask you to evaluate the entropy of a particular scenario. Others will require you to identify the entropy of different states of matter.

Quiz & Worksheet Goals

The quiz will test you on the following topics:

  • Finding the substance with the highest entropy value at a given temperature
  • The order of phases
  • Positive entropy changes and positive delta S
  • Something that exemplifies high entropy

Skills Practiced

You will practice the following skills:

  • Reading comprehension - ensure that you draw the most important information from the related entropy lesson
  • Making connections - use understanding of the concept of entropy to identify the order of phases where it goes from low to high
  • Critical thinking - apply relevant concepts to examine information about compounds and states of matter in a different light
