A cylindrical metal of radius 2 cm and height 4 cm was heated to transfer heat energy into cold palm oil at a rate of 50 kJ/mol. The temperature of the hot body is 75°C, and the temperature of the palm oil after some time is 35°C. Use this information to predict the material used in making the cylinder.
Additional information:
Surface area of the cylinder is calculated as:
A = 2 πr (r + h)
Boltzman constant is 5.67 x 10^-8 W/mk.
d = 4cm
