If you’re running, what type of energy conversion takes place a. Mechanical energy is converted to chemical energy. Has the movement for movement creates reactions in the surrounding air. B. Chemical energy is converted to mechanical energy. Is the energy from digested food provides energy for movement. C. Thermal energy is converted to mechanical energy. Is the energy from heat provides energy for movement. D. Mechanical energy is converted to thermal energy is the energy for movement creates heat in the surrounding air.
B. Chemical energy is converted to mechanical energy. Is the energy from digested food provides energy for movement.
B. Chemical energy is converted to mechanical energy. The energy from digested food provides energy for movement.
The correct answer is B. Chemical energy is converted to mechanical energy. When you are running, the energy required for movement is provided by the chemical energy stored in the food you have digested. This energy is converted into mechanical energy, which is responsible for the physical movement of your body.
To arrive at this answer, you can eliminate options A, C, and D by considering the processes involved in running and the principles of energy conversion.
Option A states that mechanical energy is converted to chemical energy. This is not the case in running, as mechanical energy refers to the energy of motion, while chemical energy pertains to the potential energy stored in chemical bonds. Running does not involve the creation of reactions in the surrounding air.
Option C suggests that thermal energy is converted to mechanical energy. While some heat is generated during running, it is not the primary source of energy for movement. Thermal energy refers to the energy associated with the temperature of an object or substance, and it is not directly converted into mechanical energy.
Option D states that mechanical energy is converted to thermal energy resulting in the creation of heat in the surrounding air. While some heat is indeed generated during running, it is not the primary energy conversion observed. The primary energy conversion involves chemical energy being converted to mechanical energy.
Therefore, option B is the correct answer as it accurately describes the energy conversion that takes place during running.
