Unit 10
Temperature and Expansion

Reading
BJU: Ch. 14
Lecture Outline
Topic 1: Thermal expansion of solids, liquids, and gases
  • Be able to use the first 2 equations, below, to solve problems connected with thermal expansion. 
  • You 'look up' the values of alpha and beta in tables. Each substance will be different. 

Topic 2: Temperature scales of Celsius, Kelvin, and Fahrenheit
  • Be able to convert between all 3 temperature scales
  • Always use absolute temperature (Kelvin) when using the gas laws

Topic 3: Gas Laws
  • Charles', Boyle's, and Gay-Lussac's Laws are interesting, BUT ALL YOU NEED is the "Combined Gas Law" because it combines all three!
  • The unnecessary terms will just 'drop out' of the Combined Gas Law formula.
  • Use the Ideal Gas Law when the problem gives you (or asks for) the number of moles of gas "n". 
  • Make sure you use units for pressure and volume which match your chosen value of 'R', the gas constant. 
  • 'R' can be stated in any combination of units you want, you just need to look up its correct value for whatever units you're using.
