The temperature of a body differs from that of a medium, whose temperature is kept constant, by 40 °C. In 5 min, this difference is 20 °C. (a) What is the value of k? (b) In how many minutes will the difference in temperature be 10 °C?
[tex]T_B-T_M = \left ( T_0-T_M \right )e^{-kt}[/tex]
Do we know k is negative only because of what's said in part (b)?
