Gradual leakage of water stored in hydrate minerals of Earth's<span> rocks could </span>have formed<span> a portion of its water. Water </span>may<span> also </span>have<span> come from volcanism: water vapor in the atmosphere that originated in volcanic eruptions </span>may have<span> condensed to form rain, slowly filling </span>Earth's<span> oceanic basins. So, the answer would be C.
I hope this helped! Good luck :)</span>
Liquids have more kinetic energy in their particles compared to solids. this allows the particles to move more freely, hence why they are fluids
Liquids diffuse from a region of high concentration to a region of low concentration, until equilibrium is reached
When heat is applied the particles gain more kinetic energy so they now have enough energy to overcome the bonds holding them in the liquid. this means they can evaporate off
YYe the answer is mechanical
Answer:
See explanation
Explanation:
When a beaker of ethanoic acid is placed in the refrigerator, its temperature drops and the vessel feels cool.
Now, when we mix ethanoic acid and sodium carbonate, an endothermic reaction occurs, fizzing is observed as carbon dioxide is given off and heat is lost to the surroundings causing the reaction vessel to feel cool to touch.
The difference between putting ethanoic acid in the refrigerator and adding sodium carbonate to the solution is that, in the former, no new substance is formed. The substance remains ethanoic acid when retrieved from the refrigerator. In the later case, new substances are formed. The substance is no more ethanoic acid because a chemical reaction has taken place.
