Pressure
Pressure
The force exerted per unit area. It is often measured in atmospheres (atm), where 1 atm is the weight of air per unit area at sea level.
STP (Standard Temperature and Pressure)
STP (Standard Temperature and Pressure)
A set of conditions where the temperature is 0°C (273.15 K) and the pressure is 1 atm.
Temperature
Temperature
A measure of the average kinetic energy of particles in a substance.

Study Notes
Gases
- Gases expand spontaneously
- Gases are highly compressible
- Gases have low density
Pressure
- Pressure is force exerted on an area
- Common unit: atm (atmosphere) - weight of air per unit area
- Other units: 760 torr = 760 mmHg = 101.325 kPa = 1.013 bar
- Pressure is caused by gas particles hitting the container's surface
STP
- Standard Temperature and Pressure
- 0°C and 1 atm
- Used for calculating gas properties
Temperature
- Temperature measures average kinetic energy of gas particles
- Use Kelvin scale in gas law calculations (K = °C + 273.15)
Basic Gas Laws
Boyle's Law
- Relates pressure and volume
- Pressure and volume are inversely proportional (P1V1 = P2V2)
Charles's Law
- Relates volume and temperature
- Volume and temperature are directly proportional (V1/T1 = V2/T2)
Gay-Lussac's Law
- Relates pressure and temperature
- Pressure and temperature are directly proportional (P1/T1 = P2/T2)
Avogadro's Law
- Relates moles and volume
- Volume and moles are directly proportional (V1/n1 = V2/n2) at constant temperature and pressure. (At STP, 1 mole of any ideal gas occupies 22.4 liters.)
