Its the urine, cant be blood because salt draws out water and blood its mostly made of that, sodium is salt, and water? well just no
Answer: (It is an endothermic reaction because energy is gained.)
It converts energy in food into a more usable form.
Answer:
The kinetic molecular theory explains the expansion of a solid material with increases of temperature as basically the result of <u>molecules moving a little farther apart.</u>
Explanation:
The kinetic-molecular theory explains the changes of state in the following way: When a solid is heated, its particles increase their kinetic energy, so that the vibration becomes more and more intense until, having reached the melting temperature, they become so weak that the particles acquire freedom of movement, that is, if we increase the temperature of a solid material system, its molecules will move faster and the average distance between them will increase, the cohesion forces decrease and there will come a time when these forces are incapable to keep the molecules in fixed positions, the molecules can move.
