He proposed the Law of Conservation of Matter, being the first to say that matter can not be created nor destroyed.
Answer: Molecules only speed up when given energy, such as heating. When you heat water enough, it will boil and turn into water vapor. So, therefore, if water's molecules speed up, it will go into the gas phase
Explanation: As that liquid water is further heated, it evaporates and becomes a gas—water vapor. These changes between states (melting, freezing, and evaporating) happen because as the temperature either increases or decreases, the molecules in a substance begin to speed up or slow down.
Hope this helps! ^w^
Since the oxygen likes to hog all the electrons, it gives the hydrogen molecules a slight positive charge and the itself a slightly negative charge.
Positive attracts negative, so there is some sort of attraction between water molecules, though a weak one.
Answer:
The answer to your question is d.
Explanation:
Chemical changes happen when the substance changes its original properties to form a new one. So option 1 is incorrect.
Dissolving a new substance does not form new substances as I mentioned before. The second option is incorrect.
The third option is also wrong because dissolving a substance does not separate anything.
The fourth option is correct, dissolving a substance allows us to make solutions.
