Answer:
The answer is 24 (for the first question).
Explanation:
<h2><u><em>
PLEASE MARK AS BRAINLIEST!!!!!</em></u></h2>
B. Purchase a small plastic container and mark 1-ounce increments on the outside to determine volume. Pour 5 ounces of water into the container, and place in the freezer for 8 hours. Compare the frozen or ending volume with the liquid or beginning volume.
<h3>How much water expands when frozen?</h3>
Ice is less denser than the liquid form. Water is the only known non-metallic substance that expands when it freezes because it is the unique property of water. Water density decreases and it expands approximately about 9% by volume. For calculating the expansion of water, plastic container is the best option. We know that water expands when the water freezes because it is a unique property of water which allows the survival of aquatic organisms.
So we can conclude that option B is the right answer.

Answer:
El resorte al comprimirse adquiere energía potencial elástica.
Explanation:
Por conservación de la energía, y si no hay agentes externos (como pérdida de energía por rozamiento), la energía cinética que proviene del movimiento de la puerta al abrirse se transfiere al resorte en forma de energía potencial elástica cuando el resorte se comprime.
En el proceso de descompresión ocurre lo contrario, es decir, la energía potencial elástica del resorte se transforma en energía cinética que es transferida a la puerta para cerrarse.
Por lo tanto, el resorte al comprimirse adquiere energía potencial elástica.
