What are the four states of matter?

What is solid, liquid, gas, and plasma?

100

What is the definition of Heat?

kinetic energy moving from one place to another, measured in Joules

100

At how many degrees Celsius does water change from the solid to liquid state?

What is 0 degrees Celsius?

100
What is the change of a liquid to a vapor throughout the liquid?
What is boiling?
200
What is matter made up of?
What is tiny particles called atoms and molecules?
200
What is the mount of force exerted on a given area of surface?
What is pressure?
200
Compare and contrast freezing and melting point.
What is melting point is the temperature at which a substance changes from a solid to liquid and freezing point is the temperature at which a substance changes from a liquid to a solid. They both occur at the same temperature since they are the reverse process of each other.
200
What kind of change is freezing and melting point?
What is freezing point is an exothermic change because energy is removed from the substance as it changes. Melting point is an endothermic change because energy is gained by the substance as it changes state.

Describe the motion and attraction of particles in a solid, liquid, and gas.
What is the particles in a solid are tightly packed together, have a strong attraction, and can hardly move, particles in a liquid are more spread apart and can move, and particles in a gas are even more spread apart and move faster and are less attracted to each other than particles in a liquid.
300
What is a measure of how fast the particles in an object are moving?
What is temperature?
300

At what temperature Kelvin does water boil?

What is 373 degrees Kelvin?

300
What is a change of state from a liquid to a gas?
What is evaporation?
400

Which states of matter have a defined volume?

Which states of matter have a defined shape?

Volume = Solids and liquids

Shape = Solids. (liquids and gas fill their containers)

400

Which phase changes are endothermic and which phase changes are exothermic?

freeze and condensing = exo

Melting and evaporating = endo

400

if c = 20J/gC
m = 100g
and q = 20000J

What is the change in temp?

10 degrees C

400
What is a change of state from a gas to a liquid?
What is condensation?
500

How does water break the normal rules of matter and why?

Hydrogen bonds cause solid water to form a crystal lattice that is spread out and it is less dense than liquid water.

500

What is heat of fusion?

How much every it takes to convert from solid from to liquid form.

500

What is the Specific heat Capacity of liquid Water?
without peeking at the reference table

4.18 J/(g x Degrees)

What is a change of state from a solid to a gas?

What is sublimation?
