When hot water is poured into cold water, the hot water will transfer its heat energy to the cold water, causing the overall temperature of the mixture to increase. Eventually, the hot and cold water will reach a thermal equilibrium where they have the same temperature throughout the mixture.
When the metal is poured into the Styrofoam cup of water, the heat stored in the metal is transferred to the water and the cup. This transfer of heat causes the temperature of the water and the cup to increase, as the metal cools down.
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.
When you put a cup of hot water with dye on a glass of cold water, the hot water will rise to the surface of the cold water due to differences in temperature and density. This creates a mixing or diffusion effect, causing the dye to spread and color the cold water as the two temperatures equalize.
The water on the cup most likely came from a water source such as a tap, faucet, or water dispenser. It could also have been poured from a water bottle or another container.
The cold lemonade cool the temperature of the plastic cup including the outer side of it. Thereby lowering the amount of water the air can contain, resulting in water condensating - attaching to the cup.
the water molecules are getting cold

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).
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.
No, hot water poured into a cup is in liquid form, not a gas. At higher temperatures, water molecules move more quickly and can evaporate into steam, which is the gaseous form of water.

1/3 cup or 1/4 cup
I loosened the cap and poured the water into the 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.
