1. To make it so molecules do not interact (ideal), they want to be far apart, which means a ___________ temperature and ______________ pressure will create ideal conditions.

Ideal Conditions

+ Variables of the Ideal Gases

+

1. Pressure: the amount of force upon an object; measured in __________.

2. Temperature: how fast molecules are moving; measure in ________________.

3. Absolute Zero: 273o below OoC. Atoms have ________ energy.

New Gas Units

+ MAD Skillz: Convert Celsius units to Kelvin

Use the equation: K = CO + 273

If I have a substance that is 23oC, then what is it in

Kelvin?

+ MAD Skillz: Convert Celsius units to Kelvin

Use the equation: K = CO + 273

If I have a substance that is 260K, then what is it in

Celsius?

+ MAD Skillz: Convert units used in ideal gases

Conversion Ratios1 Liter = 1000mL

1atm = 760 mmHg

Convert 1520mmHg to atm.
