C because you don’t put a force of which you choose and the force wouldn’t be strong enough
<span>It does not matter where the system starts but it will reach to an equilibrium state when the equilibrium ratio is reached.
hope it helps </span>
The building is in solid phase. Its molecules are arranged in a ver compact manner that is why it takes a definite shape and volume. When it is heated, the kinetic energy of the molecules increases. This is characterized by more frequent collisions. The rise in temperature causes the molecules to move rapidly by vibrating. When it reaches an amount of energy that causes the solid to change phase, this is called the latent energy. The molecules break their form and move farther away from each other until it resembles that of a liquid melting. This phase change is known as melting. The energy that must be reached to achieve melting is the latent heat of fusion.
Answer:
maybe c. because if you do 70
Explanation:
-50 you get 20 than you add that to the 25 and you get 45 and the nearest closest number is 47
