Here is the problem:
Suppose that a body with temperature 85F is discoveredat midnight, and that the ambient temperature is constant 70F. The body is removed quickly (assume instantly) to the morgue where the ambient temperature is maintained 40F. After one hour the body temperature is found to be 60F. Estimate the time of death.
I know the formula is dT/dt= -k(T-T(s))
T(inital)= 85F
T(s)= 70F
T(s2)=40F
t=1, T=60
I am confuse with the two different tempt. I dont know to use
T-70=Ce^(-kt)
or
T-40=Ce^(-kt)
PLease help
