Answers
Answer:
Due to exothermic reaction
Explanation:
During an exothermic reaction bonds break and new bonds form and protons and electrons go from a structure of higher potential energy to lower potential energy. During this change, potential energy is converted to kinetic energy, which is the heat released in reactions
Explanation:
1. energy that are particularly important in biological systems, including kinetic energy (the energy of motion), potential energy (energy due to position or structure), and chemical energy (the potential energy of chemical bonds).
2. gravitational potential energy increases, conversion is arguably a misleading word, suggesting as it does that one thing changes into another thing. Rather, energy is a conserved quantity, and one that is calculated according to a fixed recipe: for a ball near the Earth's surface (ignoring air resistance) we add mgh to 12mv2. The proportions of these two terms change as the ball rises, but we're still calculating the same thing – Energy.
3. kinetic energy of large objects can be converted into this thermal energy. For example, if you drop a water balloon onto the ground, its kinetic energy is converted mostly to thermal energy. If the balloon weighs 1 kilogram and you drop it from about 2 meters, it will heat up by less than .
4. Electric heating is any process in which electrical energy is converted to heat. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical appliance that converts electrical energy into heat.
5. The part of the speaker that converts electrical into mechanical energy is frequently called the motor, or voice coil. The motor vibrates a diaphragm that in turn vibrates the air in immediate contact with it, producing a sound wave corresponding to the pattern of the original speech or music signal.
