This assignment covers various topics related to energy and thermal storage systems. It starts by explaining the importance of energy conservation in reducing energy consumption across different systems, such as turning off cooling and heating systems. The first problem involves calculating the temperature rise of a car's braking system when it stops from an initial speed of 30 m/s, assuming the energy produced by the wheels is the same energy used to stop the vehicle. The second problem deals with three kilograms of molten lead that cools down over time, and we need to find the rate of loss of energy from the lead, the specific latent heat of fusion of lead, and the specific heat capacity of molten lead. Finally, the assignment provides examples of real-world applications of thermal energy storage systems and asks students to explain the behavior and response of an air-cooled engine using scientific concepts and principles.
