The rate of change of temp w.r.t time is -1.875°F
What is rate of change?
The rate of change (ROC) measures how quickly a variable alters over a predetermined amount of time. When discussing momentum, the term "rate of change" (ROC) is frequently used. It is typically defined as the ratio of a change in one variable to a matching change in another; visually, the rate of change is represented by the slope of a line. The Greek letter delta () is frequently used to represent the ROC.
The term "rate of change" (ROC) describes the rate at which something changes over time.
Thus, it is not the amount of individual changes themselves but rather the acceleration or slowdown of changes (i.e., the pace).
Time Temperature Difference
4 89.5 -
10 78.25 78.25 - 89.5 = -11.25
16 67.00 67 - 78.25 = -11.25
There is a common difference of -11.25 in each successive term.
Therefore, cooling of a chemical represents a linear function.
Rate of change of temp from 4 min to 10 min
=78.25 - 89.5 = -11.25
= -11.25/6
=-1.875
So, the rate of change of temp w.r.t time is -1.875°F
which means temperature is decreasing continuously when the time is increasing
