Question

An object with initial temperature 120 F is submerged in large tank of water whose temperature is 60 F. Find a formula for F(t), the temperature of the object after t minutes, if the cooling constant is k = 0.4

F(t) = __________

Answer 1

Assuming that k=0.4 F/min,

F(t)=120 - 0.4t

This is a calorimetry problem that would actually require specific heat and mass data.
