I'm preparing a paper on heating systems which work automatically, the basic idea being that a switch is required to turn the heating on when the temperature falls below a set value.

List temperature-dependent changes in materials properties (one each from gradual, accelerating and sudden) that could be exploited in a 'cold' sensor that could be used to turn the heating system on and off.

Taking it a step further could these be used in 0 degrees C?

Thanks...

Sounds like a T207 TMA question to me

Yeah it is .. been working through the book
im applying a, bi-metal switch, thermistor and SMA to gradual , accelerating,and sudden principles.
