200
What a force can cause an object to do.
What is to change direction, change speed, or change shape?
200
What pH stands for.
What is the power of Hydrogen (the number of hydrogen ions in a solution)?
300
The number of neutrons in the element below (remember to round to the nearest whole number!).
What are 118 neutrons?
300
The difference(s) between evaporation and boiling.
a) They are the same.
b) Evaporation is when only the particles at the bottom have enough KE to break their liquid bonds. Boiling happens to all particles throughout the liquid.
c) Evaporation occurs at all temperatures with all particles at the surface, and boiling occurs at the liquid's boiling point and with all particles throughout the liquid.
d) Boiling occurs at all temperatures with all particles at the surface, and evaporation occurs at the liquid's boiling point and with all particles throughout the liquid.
What is c) Evaporation occurs at all temperatures with all particles at the surface, and boiling occurs at the liquid's boiling point and with all particles throughout the liquid?
300
A 50 kg roller coaster has 8500 J of total mechanical energy at Point A. This point is 20 m above the ground and the roller coaster is traveling at 12 m/s. How much total mechanical energy will it have at Point B when it is 10 m above the ground and traveling at 100 m/s? Friction is negligible.
What is 8500 J of total mechanical energy?
300
A physics student is pulling upon a rope which is attached to a wall. The physics student is pulling upon the rope which is held by the Super Person. In each case, the force scale reads 500 Newtons. In which scenario is the physics student applying more force?
What is the same force?
300
True or False: A strong acid, when compared to a weak acid, is one that has a greater concentration of Hydrogen ions.
What is true?
400
The column number on the PTE where noble gases are located.
What is column 8?
400
True or False: This equation is balanced.
4FeS + 70_2 -> 2 Fe_2 0_3 + 4 SO_2
What is true?
400
The three misconceptions of Newton's third law of motion.
1. It is the law of action-reaction.
Correction: Should be called the law of interacting force pairs.
2. Equal forces cause equal effects.
Correction: Equal forces do not mean equal effects.
3. Both objects are affected by both forces in the interaction force pair.
Correction: Only the force acting on the object is felt by the object.
400

b) You are pulling on a rope in tug-a-war. What force are you applying?
a) What is compression?
b) What is tension?

500
What the rows on the PTE tell you.
What is the number of electron shells?
500
The two questions to ask to tell if something is a physical or chemical change.
1. Can it be reversed? (can we get back to where we started?)
2. Was a new substance created at the chemical/molecular level?
