A mat if s better conductor of heat than the feet
Mat losses heat to the bare feet at a faster rate than concrete floor
Mat losses heat to the bare feet while the concrete floor extracts heat from them
Concrete floor is a better conductor of heat than the mat
Mat is a better conductor of heat than the floor

46.0 Nm-2
75.0 Nm-2
80.0 Nm-2
85.3 Nm-2
139.4 Nm-2
Correct answer is B
P1/T1 = P2/T2
80/(273+47) = P1/(273+27) = 75Nm-2
