These are the two main categories of matter.

1, 100

What are pure substances and mixtures?

1, 100

These are four of the 7 physical properties of matter we learned.

1, 200

What are conductivity, malleability, density, hardness, viscosity, melting point, and

boiling point?

1, 200

Mixtures can be classified as solutions, colloids, or

suspensions based on the size of these.

1, 300

What are the largest particles?

1, 300

These are the four main indicators that a chemical change

has occurred.

1, 400

What are formation of a precipitate, production of a gas, change of color,

and releasing or taking in heat?

1, 400

This is the type of mixture that cannot be filtered but does

disperse light.

1, 500

What is a colloid?

1, 500

This is the phase change where a liquid turns into a gas.

2, 100

What is vaporization?

2, 100

This category of phase change occurs when the substance

absorbs heat from its surroundings.

2, 200

What is endothermic?

2, 200

During a phase change the temperature does this.

2, 300

What is stays the same.

2, 300

This is the approximate condensation temp. of the

substance whose T vs. E graph is below.

shown in the T vs. E graph below.

Any type of energy can be categorized as one of these two

main types.

3, 100

What are potential and kinetic energy?

3, 100

Whenever energy transforms from one form to another, some of the energy is always lost as

this.

3, 200

What is heat?

3, 200

The first law of thermodynamics says this.

3, 300

What is energy can neither be created nor destroyed?

3, 300

When heat flows, it always flows in this direction.

3, 400

What is from hot to cold? (everything flows from high

concentration to low concentration by itself, you can

think of cold as a low concentration of heat)

3, 400

These are two of the three things that are often used to show the

kinetic theory of matter is correct.

3, 500

What are Brownian motion, thermal expansion, and diffusion?

3, 500

This is what temperature is related to.

4, 100

What is the average kinetic energy of particles

4, 100

Of 0oC water and 0oC ice, this is the one with the greater total internal

energy

4, 200

What is 0oC water.

4, 200

Of 0oC water and 0oC ice, this is the one with a greater average

kinetic energy.

4, 300

What is 0oC water and 0oC ice have the same average kinetic

energy

4, 300

This is why nothing can be cooled below absolute zero.

4, 400

What is absolute zero is the temperature all molecular motion

stops, since temperature measures average kinetic energy, if there is no motion, there is no

KE, and thus no temperature, and you can’t make the molecules

move slower than stopped.

4, 400

This is why heat of vaporization is typically greater than heat of fusion for a

particular substance

4, 500

What is to vaporize, the molecules need to gain enough energy to completely break free of and separate from neighboring molecules, while when melting, the molecules need to only gain enough energy to be able to flow

passed, but still touch the neighboring molecules.

4, 500

Pressure is defined as this.

5, 100

What is force distributed over a certain area?

5, 100

Gas pressure in a closed container is caused by these.

5, 200

What are collisions between the gas particles and each other and the sides

of the container?

Pressure is affected by other things, but not caused by them

5, 200

These four things affect gas pressure in a closed container.

5, 300

What are number of particles, temperature of the gas, volume of

the container, and type of gas?

5, 300

These are the two pairs of quantities that are directly

proportional in closed container of gas when everything else is

constant.

5, 400

What are temperature and volume (Charles’ Law) and temperature and

pressure (Gay-Lussac’s Law)?

5, 400

This is the final size of an air bubble if it starts out 10ml, with

a temperature of 10oC and pressure of 4atm, and then

proceeds to go to a location with a pressure of 2atm and temperature of 20oC.

5, 500

What is 20.7ml?

P1V1/T1 = P2V2/T2

10 C = 283K; 20 C = 293K4*10/283 = 2*V2/293

V2 = (4*10*293)/(283*2) = 20.7ml
