The properties of a heterogeneous mixture
Parts of the mixture can be separated
100

Significant figures in 301

What is 3?

When a sealed balloon is heated, its volume expands because THIS happens to the speed of the particles.

What is the particles move faster?

200

The phase of matter with the strongest intermolecular forces

What is solid?

200
The properties of a homogeneous mixture
It appears to be one indistinguishable mixture
200
The definition of precision
What is the ability to reproduce results?
200
Examples of physical properties
What are hardness, conductivity, color, shiny, etc
200

An aerosol can left in a hot car can explode. Explain the reason using gas behavior.

What is heating increases the kinetic energy of the gas, raising pressure until the can bursts?

300

What do the diagonal parts of a heating curve represent?

What is solid, liquid, or gas

300
The difference between physical and chemical change
Physical change alters the state of the matter, but it is still the same material. Chemical change completely changes the reactants
300

Significant figures in .00001

What is 1?

300
The SI unit for energy
What is a joule?
300

When the same number of gas molecules are placed in a large container and a small container, THIS container will have the lower pressure.

What is the larger container?

400

This phase change is endothermic

What is melting, evaporation, or sublimation?

400
The signs of a chemical change
What are color change, gas (bubbles), precipitate, and temperature change?
400
The number produced from 4 x 10^2
What is 400?
400

The formula for finding the amount of heat needed to boil water from 0 - 100C?

What is q = mC(change in Temp)

400

If the volume of a rigid gas cylinder is fixed and the gas inside is cooled, THIS is what happens to the pressure.

What is the pressure decreases?

500

This increases during a phase change

What is potential energy?

500
This states that mass cannot be created or destroyed
What is the law of conservation of matter?
500

Grams in a kilogram

What is 1000?

500

List the phases of matter in order from increasing intermolecular forces.

What is gas, liquid, solid?

A sealed bag of chips looks puffed up when you bring it on an airplane. Explain why the bag expands even though the amount of air inside hasn’t changed.

What is the external air pressure decreases at high altitude, so the trapped gas inside the bag expands to balance the pressure difference?
