Explanation:
<span>For the question "A light shines up from the bottom of a fish pond.
Which diagram shows the correct path of light as it leaves the water of the pond and hits the air?"
The second diagram is the correct answer.
Water has a higher refractive index than air so the ray of light passing from water to air will be refracted away from the normal (the vertical) towards the surface of the water.</span>
The volume of the water, which was initially 100mL changed to 96mL after refrigeration because the volume of water reduces when cool.
<h3>Why does water change in volume?</h3>
Water is a substance that is known for its unique characteristics that makes it stand out among all other liquids.
One notable feature of water is it's ability to become denser when subjected to cooler temperatures i.e. water is more dense when cold.
As water cools or becomes less warm, it contracts and decreases in volume. When water decreases in volume, it becomes more dense.
Therefore, according to this question, it can be said that the volume of the water, which was initially 100mL changed to 96mL after refrigeration because the volume of water reduces when cool.
