This study guide is specifically covering Chapters 2-4, and reflects questions from the readings, clicker  quizzes, and homework. The concepts covered have the potential to be on the exam, and should be  covered in more depth than just this study guide, but this is a great way to check your understandings  of general concepts that will be tested. Good luck and Roll Tide!

Potential Energy: energy matter has because of its location or structure

a. An electron’s state of potential energy is called energy level (or electron shell)

b. The more distant an electron is from the nucleus = greater potential energy 

i. Energy is required to move an electron away from the nucleus

1. ie: absorbing light energy in photosynthesis

ii. Energy is released when moving to a lower shell (closer to nucleus)

1. ie: releasing energy usually in the form of heat


 Water is effective as a heat bank because it can absorb or release a relatively large 

amount of heat with only a slight change in its own temperature

 Temperature and Heat

∙ Specific heat of a substance is the amount of heat that must be absorbed or lost 

for 1g of that substance to change its temperature by 1°C.

 Calorie is the amount of heat it takes to raise the temperature 

of 1g of water by 1°C.

o The greater the specific heat of a substance, the greater it resists 

changing temperature when it absorbs or releases heat.

 Compared to other substances, water has an unusually high 

specific heat.


o The high specific heat of water minimizes temperature fluctuations to 

within limits that permit life, and because organisms are made 

primarily of water, they are better able to resist changes in their own
