Explicit physics instruction
Thermal synthesis connects microscopic models, q=mcΔT, transfer mechanisms, and energy conservation.
Use the Friday transfer to distinguish temperature from energy and mechanism from amount.
Two objects at the same temperature need not contain the same internal energy; mass and material matter.
Core relation: q=mcΔT; energy conservation across a defined thermal system.
Worked example
Heating 100 g of water by 5°C with c=4.18 J/(g·°C) requires q=100×4.18×5=2090 J.
Guided question
Build an energy-flow diagram for a cooling object and name all three transfer modes.
Independent work

- From Week 27: identify energy losses in real fluid flow.
- From Week 13: interpret efficiency as useful output/input.
- From Week 11: define a system boundary for energy conservation.
