Your neighbor has circular steel lid for his well. The lid has an outer diameter of 0.909 m. The circular well itself has an inside diameter that is 1.46 mm smaller. After hearing your professor talking about heat expansion in class, you begin to wonder if it would be possible to cool down the lid enough so that it would fit inside the well (after which it will quickly expand and block the well very efficiently). To what temperature do you have to cool the lid (assuming of course that there is a linear relationship all the way to that temperature)? Assume that the well is at room temperature of 20°C. i °℃
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.
In this linear expansion problem, we know that the linear coefficient of steel is 12*10^-6. How would I put all the information together to solve this question? Please show all steps
