Study Notes
Atmospheric Introduction
- The atmosphere is the gaseous envelope that surrounds the Earth, extending up to 500 km above.
- It is composed of different gases, with N2 (79%) and O2 (20%) being the most abundant.
Atmospheric Properties
- Temperature: measures the thermal or internal energy of molecules, closely related to pressure, volume, and density.
- Density: measures the 'heaviness' of an object or substance, related to the type of material and how closely packed it is.
- Pressure: force exerted over a given area or object, due to gravity or motion, connected to other atmospheric properties.
- Humidity: measures the amount of moisture in the air, affecting comfort and cloud formation.
Composition of Atmosphere
- N2 (79%) and O2 (20%) are the most abundant gases.
- O3 (ozone) is a triatomic form of oxygen that absorbs ultraviolet solar radiation.
- Water vapor (up to 4% of the atmosphere) is responsible for cloud formation, precipitation, and is a greenhouse gas.
- Carbon dioxide (CO2) is a greenhouse gas emitted by industrial processes, contributing to climate change.
Thermodynamic Properties of Atmosphere
- Temperature is related to volume, pressure, and density in the atmosphere.
- Adiabatic expansion and lapse rate are important thermodynamic properties of the atmosphere.
