Consider a small pot with an aluminum base. The base has a thickness of 2.0mm and a diameter of 19 cm. Water in this pot is boiling at 100. 'C. Heat transfer rate is estimated at 101,000 J/s. Assume that heat enters the water only from the bottom of the pot through the aluminum base. Find the temperature of the heating element on which the aluminum bottom rests to 3 sig fig. revious F5 F8 AA 6 The star Mintaka in the Orion constellation is about 30x larger than our sun with a radius of 5.74 x 10^9 m. It's surface temperature is about 29,500 K. Consider the spherical surface to behave as a blackbody radiator. What is the rate at which energy is radiated from this star, to 3 sig fig?

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.
