En längre mätning av temperaturen när vatten svalnar
Här finns en fil med värden från en längre mätning.
Dessa värden ligger här i GeoGebra och jag har försökt få till en kurvanpassning med RegressionExp[] men det funkar inte så bra. Fundera på varför exponentialfunktionen passar så dåligt till värdena.

För bra kurvanpassning bör man addera en konstant term. I detta fall har jag till och med lagt till lite mer än rumstemperaturen. Så här ser en bättre kurvanpassning ut:
