IB Physics SL B.1.12 Conduction rate
Practise conduction calculations by using thermal conductivity, area, thickness and temperature difference to find energy transfer rates and read graph changes.
How this is tested
- use q/t = kAΔT/x to calculate conduction rate or rate per unit area, then give the final unit as W or W m^-2
- use a temperature-distance graph gradient to infer conduction rate as ΔT falls during cooling
- decide how changing thickness x in q/t = kAΔT/x alters the rate and the temperature gradient through a layer
