Explain the difference between a calorie and a Kilocalorie.

A calorie is the amount of energy needed to raise the temperature of 1 gram of water 1o C. A Kcal raises the temp of 1000 grams of water 1o C.

List the 5 steps of the Scientific Method.

1. Ask a question

2. Make a hypothesis

3. Experiment

4. Organize and Analyze Data

5. Evaluate the hypothesis

Name three of the six changes in the common states of matter, and correctly label the states which they change from and to.

Condensation--gas to liquid

Vaporization--liquid to gas

Freeze--liquid to solid

Melt--solid to Liquid

Deposition--gas to solid

Sublimation--solid to gas

Define the "Heisenberg Uncertainty Principle."

It is impossible to know the velocity and the position of an electron at the same time.

1000

Define the term "Periodic Law."

Properties of elements vary with their atomic numbers in a systematic way.
