Newtons Cooling Law
If you were to compare the rate of cooling of the soup inside a sealed styrofoam container, and
inside a metal pot, which one might correspond to a larger value of k?
Solution
Rate of change of object = k ( T ( s )- T ( t ))
Where
k is the medium constant
When its hotter than surroundings: T ( t )> T ( s ), the rate of change is negative
When its cooler than surroundings: T ( t )< T ( s ), the rate of change is positive
Hence the rate of cooling the soup inside a sealed Styrofoam container correspond to a larger
value of k
