When you move your muscles chemical energy in the cells is converted into mechanical and thermal energy What is this an example of law of nutrition law of conservation of energy theory of photosynthesis theory of kinetics?
Explanation: In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.
What happens when chemical energy is converted into thermal energy?
During conversions from chemical energy to thermal energy, the energy stored in the chemical bonds are released and this energy causes surrounding molecules to move faster thus increasing the thermal energy of a substance. The chemical energy released as the coal is burned heats water and turns it into steam.
Is chemical energy converted into mechanical energy?
Chemical energy, Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic. The chemical energy in food is converted by the body into mechanical energy and heat.
What is an example of an energy transformation from chemical to mechanical?
For example, friction caused by a mechanical device creates heat. In the same way, other forms of energy can be transformed to mechanical energy. For instance, the chemical energy of batteries can be converted to mechanical energy used to power a motor.
How is energy transformed to another form?
Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.
What type of energy transformations are involved in height and altitude?
Gravitational Energy is energy stored in an object’s height. The higher and heavier the object, the more gravitational energy is stored. When you ride a bicycle down a steep hill and pick up speed, the gravitational energy is being converted to motion energy.
Why does energy turn into heat?
When sunlight hits an object, it can be reflected or absorbed. If it is reflected it bounces off at the same wavelength. But if it is absorbed, the short wavelength energy is changed to long wavelength (heat).
Does entropy increase with temperature?
Entropy increases as temperature increases. An increase in temperature means that the particles of the substance have greater kinetic energy. The faster moving particles have more disorder than particles that are moving more slowly at a lower temperature.
