A hot liquid is kept in a bog room. Accoding to Newton's law of cooling rate of cooling liquid (represented as y) is plotted against its temperature `T`. Which of the following curves may represent the plot?

Options

A.
B.
C.
D.

Answer

C

Explanation

According to Newton(s) law of cooling.
The temperature difference
`DeltaT = T_(2) - T_(1) = ce^(-Kt)`
where c and K are positive constant.
From the above expression the temperature difference is exponentially decreasing with time. Hence the curve (c ) is correct option.
