-0° freezing point ice or ice cream
Mass number<span> is found by adding the </span>number<span> of protons and </span>neutrons<span>.So </span>Fluorine<span>, which has </span>9 protons<span> would be added to the </span>number<span> of neutrons, </span>8<span>. Therefore, the mass number of fluorine would be 17. Hope this helps. Have a nice day.</span>
Answer:
Their vibrations speed up
Explanation:
They start vibrating faster and faster and start generating more and more heat and separate from each other so, therefore (usually), become less dense
Answer:
Chemical change
Explanation:
Matter changes into a new substance by changing into a chemical change. In a chemical change, the substance cannot be changed back to its previous state and a new substance is formed.
Answer:
The volume will decrease
Explanation:
Since PV = nRT, and P is unchanged and T increases, the volume will decrease because the right and left sides of the equation have an inverse relationship. So as T increases, V must decrease to balance the equation.
