Mass of the atmosphere
- The atmosphere is a body of gas.
- To understand variations in temperature, volume and pressure we must understand the mechanical laws of gas.
- Two simple laws govern the changes in pressure
- Boyle's Law
- At a constant temperature the volume is
inversely proportionate to the pressure.
- p = (k1/v)
- Where k1 k2 are mathematical constants
- When working with gases temperature
must always be expressed in Kelvin (which
is degrees Celsius temp added to 273)
- When working with gases temperature
must always be expressed in Kelvin (which
is degrees Celsius temp added to 273)
- Where k1 k2 are mathematical constants
- As pressure goes up volume goes down
- p = (k1/v)
- At a constant temperature the volume is
inversely proportionate to the pressure.
- Charle's Law
- At a constant pressure, volume varies directly with
absolute temperature measured in degrees Kelvin
- v = (k2 V)
- The higher the temperature the
higher the kinetic energy of the
gas, needs more room then if in
low temperature.
- Thus, low temp means low volume.
- Thus, low temp means low volume.
- v = (k2 V)
- At a constant pressure, volume varies directly with
absolute temperature measured in degrees Kelvin
- Boyle's Law
- All interdependent
- Two simple laws govern the changes in pressure
- highly compressible
- To understand variations in temperature, volume and pressure we must understand the mechanical laws of gas.
- One half of the total mass of air is found below 5km
- at lower levels it is more dense
- at lower levels it is more dense
