A hot liquid is kept in a big room. According to Newton's law of cooling rate of cooling of liquid (represented as y) is plotted against its temperature T. Which of the following curves may represent the plot?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Rate of cooling, y = (T – T 0 ) k (from Newton's law of cooling)
T 0 : surrounding temperature
k: +ve constant
⇒ graph is straight line with +ve slope
