cause energy change chemical.
when a person do some vigorous exercise his enery is not lost or not increase but his energy changes from one form to another
when a person lift a very big weight he is tired because of his energy canged from one form to another
our energy is not destroyed and no increase but its only changed the form.
Energy is always involved.
Chemical energy to electrical energy.
Yes
No
It is true.
For example any chemical reaction need an activation energy.
chemical energy to mechanical energy
Water itself is not a form of chemical energy, but it is often involved in chemical reactions that produce or store energy. Water can be part of processes like photosynthesis or combustion where chemical energy is converted into other forms.
Energy changes involved in cooking include converting electrical or thermal energy to heat energy to cook food, converting potential energy in food into kinetic energy for cooking processes such as stirring or chopping, and converting heat energy to chemical energy through reactions like caramelization or Maillard browning.
Chemical and mechanical
No, at the top of a swing, the pendulum has potential energy due to its position above the ground, which is considered gravitational potential energy. There is no chemical energy involved in the motion of a pendulum at the top of its swing.
Energy can be absorbed or released in a chemical or physical change, it is not destroyed or created. It simply assumes a different form.
