How does water's ability to moderate temperature, (difficult to abruptly change temperature,) contribute to its ability to sustain life?
Helps ecosystems maintain homeostasis; helps maintain ocean currents, weather, etc.

What is voltage?
The amount of electrical force in a circuit. Caused by the potential difference in the circuit.
300
State Newton's 1st Law in your own words.
If something is not moving, it will continue to not move forever. If something is moving and there are no other force involved, it will keep moving forever.

Suppose you are rolling in a large tube down a large hill. You are 3/4 of the way down the hill. Describe the amounts of potential and kinetic energy at this point.
3/4 (75%) kinetic energy, 1/4 (25%) potential energy
400
What do you call substances that do not dissolve in water?
Hydorphopic
400
State Charles' Law in your own words.
If you increase the temperature of a gas, the volume will increase as well.

If you have a circuit with one battery and one light bulb and you add another light bulb in series, how does that affect the voltage of the second light bulb?
The light bulb will have half the voltage
400
What equation is associated with Newton's Second Law?
F=ma, Force=mass x acceleration
400
What is the Law of Conservation of Energy?
States that the total amount of energy in a system never changes.
500
What's the difference between cohesion and adhesion?
Cohesion is attraction between two substances that are the same, adhesion is attraction between two substances that are different.
500
State Boyle's Law in your own words.
If you increase the pressure of a gas, the volume will decrease.

If you have a circuit with one battery and one light bulb and you add another light bulb in parallel, how does that affect the voltage of the second light bulb?
The light bulb will have the same voltage running through it.

State Newton's Third Law in your own words.
Every time you apply a force, there is an equal and opposite force pushing back at you.

Suppose you stretched a rubber band and shot it into the air upwards. Compare the types and amounts of energy at the beginning when you stretch it to when the rubber band reached its maximum height.
Full SPE (Spring Potential Energy) when you stretched the rubber band. Full GPE (Gravitational Potential Energy) when it reaches its maximum height.
