the glass of water that has been sitting in the sun cause it gathers the heat energy
the more the temperature the more energy
hope you understand and good luck
When water molecules align with each other, a weak bond is established between the negatively charged oxygen atom<span> of one water molecule and the positively charged </span>hydrogen atoms<span> of a neighboring water molecule. The weak bond that often forms between </span>hydrogen atoms<span> and neighboring atoms is the hydrogen bond.</span>
2.03 molecules times 6.022E23 = 1.22E24
