Gases 4 Me and Camilla

### Boyle's Law

The volume of a given sample of gas at constant temperature varies inversely with the pressure

### absolute zero

-273 C is the lowest point, when converted to Kelvin, is 0. cannot be lower than this on Kelvin scale

### Charles's law

The volume of a given sample of gas at constant pressure is directly proportional to the temperature in kelvins

### Avogadro's Law

Equal volumes of gases at the same temperature and pressure contain the same number of particles (atoms or molecules)

### ideal gas law

An equation relation the properties of an ideal gas, expressed as PV=nRT The equation expresses behavior closely approached by real gases at high temperature and/or low pressure

### ideal gas

A hypothetical gas that exactly obeys the ideal gas law. A real gas approaches ideal behavior at high temperature and/or low pressure

### Dalton's law of partial pressures

For a mixture og ases in a container, the total pressure exerted is the sum of the pressures that each gas would exert if it were alone

### kinetic molecular theory

A model that assumes that an ideal gas is composed of tiny particles (molecules) in constant motion

### molar volume

The volume of one mole of an ideal gas; equal to 22.42 liters at standard temperature and pressure
