The Greenhouse Effect
Learning outcomes - after studying this topic, you should be able to:
- summarise the evidence for global warming and the greenhouse effect
- calculate the temperature of a black body emitter from its wavelength maximum or from an energy balance and suitable data
- Identify the infrared wavelength range
- convert between units of wavelength, wavenumber, frequency and energy
- describe how infrared energy is absorbed by exciting vibrational modes, and the selection rule for an infrared absorbance
1st Law of Thermodynamics
Learning outcomes - after studying this topic, you should be able to:
- define the types of thermodynamic system
- recognise electrical, PV, surface, and elastic (spring) work
- express and explain the First Law of Thermodynamics, and use it to carry out energy balances
- define heat capacity and manipulate First Law heat capacity expressions
- define the terms exothermic and endothermic
- explain how a calorimeter and a chemical thermostat work
