This unit measures temperature and is the only unit we use for equations in this module.

Kelvin 

200

What does STP stand for?

Standard Temperature and Pressure

300

For gases, scientists measure these three properties

Mass, volume, and pressure

400

Name one property required for an ideal gas.

1. Molecules are very small compared to the total volume available to the gas

2. Molecules must be so far apart that there is no attraction or repulsion between them.

3. The collisions between molecules must be elastic.

500

Define Extrapolation

Following an established trend in the data even though there is no data available for that region.

Under Pressure

100

Define pressure

the force per unit area that a gas exerts on its surroundings

200

Name three units used to measure pressure

possible answers: Pa, kPa, atm, torr, and mmHg

300

This substance will behave ideally when pressure is near or lower than 1.00 atm and when temperature is near or higher than 273K.

Gasses

400

The unit Pa was named after this brilliant French mathematician, scientist, and Philosopher.

Pascal

500

This instrument measures the pressure of the atmosphere.

Barometer

Laws

100

Born in 1627, this man was the first modern chemist and the founder of modern chemistry.

Robert Boyle

200

At constant pressure, the temperature and volume of a gas are linearly proportional. 

Charles's Law

300

Which law demonstrates that if the pressure of a gas is increased, it's volume will decrease in response.

Boyle's law

400

Boyles law and Charles law combine to form this law

The combined gas law

500

When 2 or more ideal gases are mixed together, the total pressure of the mixture is equal to the sum of the pressures of each individual gas.

Dalton's law of partial pressures

Salute to Solutes (mod 10)

100

The maximum amount of solute that can dissolve in a given amount of solvent 

Solubility

200

These are the three solute phases

solid liquid gas

300

A solution in which the maximum amount of solute has been dissolved.

Saturated solution

400

If a solute's solubility in a liquid solvent decreases when the temp increases, the solute is most likely a _________ 

gas

500

This kind of solute usually increases in solubility with increasing temperatures

Solid

This process releases heat

Exothermic

300

Define Endothermic

A process that absorbs heat

400

T or F

For a gas solute dissolving in a liquid solvent, the solvent molecules must be attracted to the solute molecules enough to pull the solute molecules closer to one another.

True
