because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.
so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.
this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.
the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.
For work to be done, force must be applied to move an object in the direction of the applied force.
Work is the product of force and distance. Workdone describes a change of energy between places.
If we apply force to a body without moving it through a distance, no work is done.
Work is only done when force is applied to move or displace a body.
If we only apply force and no movement occurs, no work is done..
The unit of force is Joules.
