1.	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?
Answer» Solution :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.
