How is thermal energy produced and dilivered to you through a flat iron?
In a flat iron, a heating element converts electrical energy into heat energy. The heat energy is conducted by the flat metal surface that ends up making contact with the clothes.
How much thermal energy is produced in an electric motor j of electrical energy are converted into 92j of mechanical energy?
In simple terms energy can never be created or destroyed it can only change form therefore you do not produce thermal energy but change a number of forms of stored energy into thermal energy. Therefore thermal energy can be produced from multiple forms of other energy - by splitting atoms, by burning fuels (coal, oil, gas, biofuels etc). Rubbing your hands together creates thermal energy from friction which is created by the muscles in your…
Nuclear fission process results in thermal energy production (this due to mass difference before and after of fission). This thermal energy is transferred to reactor coolant system. Then the thermal energy is converted into mechanical energy through turbines. The mechanical energy is converted into electrical energy through electric generators.
