Answer 5

1. Law of Conservation

2. Law of Entropy

Question 6

Law of Conservation

Answer 6

Energy cannot be created of destroyed

-Changes forms

Question 7

Law of Entropy

Answer 7

Disorder will increase

-As energy changes forms more energy is changed to forms we cannot use.

Answer 10

An exergonic reaction powering an endergonic reaction.

Question 11

Endergonic

Answer 11

Requires energy

Question 12

Exergonic

Answer 12

Gives off energy

Question 13

Energy measurement

Answer 13

Heat is measured to measure the energy of something.

• Calorie is the unit of energy measurement
• The amount of heat it takes to raise 1gram water from 14.5C to 15.5C (1 degree Celsius)
• Calorie= 1,000 calories or Kcal= 1kg water raised 1 degree Celsius.
