Can you explain why the coin was seen when water was poured into the cup?
When water was poured into the cup, the coin became more visible due to the refraction of light. The water filled the air gaps between the coin and the cup, reducing the effects of reflection and making the coin easier to see.
Why the coin was seen when water is poured into the transparent cup?
When water is poured into a transparent cup with a coin at the bottom, the light gets refracted as it passes through the water and into the air, causing the coin to appear raised and no longer hidden by the water. This phenomenon is called refraction and it makes the coin visible even though it's at the bottom of the cup.

Water from the air condensates on the glass cup. Because the air is cooling down, it can no longer hold as much humidity as it did (saturation).
Why does a coin sink in a cup of water?
A coin sinks in water because it is denser than water. The weight of the coin is greater than the buoyant force acting on it, causing it to sink.
