Can someone answer this please? Study the scenario. A fan spins in a small room. The system consists of the fan, the Earth, and the air. Which choice best describes the role of thermal energy in energy transformations? A)The fan blades also warm up as they spin, indicating that some of the electrical energy is converted to thermal energy. Thermal energy reduces the amount of electrical energy being converted into mechanical energy. B)The fan blades also warm up as they spin, indicating that some of the heat energy from the surroundings is going to the fan. Thermal energy increases the amount of electrical energy being converted into mechanical energy. C) The fan blades cool down as they spin, indicating that some of the electrical energy is converted into heat energy and going into the surroundings. Thermal energy reduces the amount of electrical energy being converted into kinetic energy. D)The fan blades also warm up as they spin, indicating that some of the heat energy from the surroundings is going to the fan. The total amount of electrical energy is all converted into mechanical energy.
