Question 1198932: A frozen steak initially has a temperature of 30 Fahrenheit. It is left to thaw in a room that has a temperature of 70 Fahrenheit. After 8 minutes, the temperature of the steak has risen to 38 Fahrenheit, After how many minutes will the temperature be 55 F.

You can put this solution on YOUR website! .
For your info and for your education:
In this problem, which includes thawing, temperature goes through the phase change temperature.
In such problems, temperature IS NOT an exponential function of time.
It is known to all who studied/learned Physics and/or Science.
THEREFORE, this problem is different from the standard " exponential decay " problems.
+-------------------------------------------------------------------+
| It is a full scale heat transfer problem, which must include |
| other additional parameters to be solved. |
+-------------------------------------------------------------------+
I tell it to you as an EXPERT in such problems.
+----------------------------------------------------------+
| So you better EXCLUDE it from your list of problems |
| until you will learn relevant theory in the future. |
