Convection The exterior walls of a house have a total area of 212 m² and are at 11°C and the surrounding air is at 6.6° C. Find the rate of convective cooling of the walls, assuming a convection coefficient of 3.1 W/(m².C). Since you're looking for the rate of cooling, your answer should be entered as positive. Conduction Ice of mass 12.2 kg at 0°C is placed in an ice chest. The ice chest has 3.1 cm thick walls of thermal conductivity 0.04 W/m-K and a surface area of 1.39 m². Express your answers with appropriate mks units. (a) How much heat must be absorbed by the ice during the melting process? (b) If the outer surface of the ice chest is at 37° C, how long will it take for the ice to melt?
Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.
