(1) A pig lying on a 2.0 cm thick wood floor has its belly in contact with the floor. Let the contact surface area of pig's belly and floor floor be 3000 cmn'. The floor is cooler than the pig's body temperature (30°C), and at a temperature of 0.0 °C. The thermal conductivity of wood is 0.126 W/m °K. What is the conductive heat transfer under steady-state conditions? (2) The Born energy EB (SI unit kcal/mol) is a measure of...
