The Greenhouse Effect

The Greenhouse Effect. Garver GEO 307. Take home points from Chapter 2. EMR carries energy through space If an object can absorb energy, it can also emit energy. Objects emit at a rate equal to T 4. Boundary to Space. VIS. IR. Atmosphere. Chapter 3: Layer Model.

Combined Gas Law

Combined Gas Law. Units first!. Volume in liters, milliliters, or cm 3 Temperature must always be in KELVIN!!! Pressure can be in atmospheres, torr, or mm of Hg, or kilopascals (kPa) 1 atm = 760 torr = 760 mm Hg = 101.3 kPa. STP.
