Heat Capacity and Latent Heat

Heat Capacity

• discussion - compare various mixtures of heating and cooling (ice in water, different masses etc.)
• Heat Capacity = DQ / DT

Specific Heat Capacity

• discussion c vs C (Hydrogen & other examples where molar mass a factor)
• c = DQ/mDT
• or DQ = mcDT

Methods to determine specific heat capacity

• notes
  • mixing type problems
  • electrical equivalent of heat
  • mechanical equivalent of heat

Latent Heat

• model of solid, liquid and gas
  • Brownian motion

  • 	bonds	KE	PE	compressibility	density
    solid
    liquid
    gas

  • solid - crystaline polycrystaline, amorphous
• DQ = mL
