with a cup with ice and coolwater
choices are: The cold will flow from the metal into the hot water, causing the hot water to warm up and the metal to cool down. b. The energy from the hot water will flow into the cold metal, cooling the water down and heating up the metal. c. The cold will flow from the metal into the hot water, causing the hot water to cool down and the metal to warm up. d. The metal will cool down because the specific heat of water is high.
Convection heat transfer occurs when hot water flows into cool water. This is because the hot water heats up the cool water through the movement of fluid.
Not necessarily. The amount of heat in a cup of hot water and a pail of hot water depends on factors like their temperature, volume, and material. In general, a pail of hot water will likely have more heat than a cup of hot water due to its larger volume and higher overall energy content.
In the cup of boiling water, the water molecules have higher kinetic energy and move faster, leading to more chaotic movement. In the cup of ice-cold water, the water molecules have lower kinetic energy and move more slowly, resulting in a more orderly and structured movement.
A hot cup of coffee will cool down at a certain rate, but as the coffee cools, the rate at which it cools slows down. This is why a "lukewarm" cup of coffee cools down so slowly. Even though the warm cup of coffee is cooling down quicker at first, the lukewarm cup essentially has a "head start" on the way to room temperature.
Glass cools hot water the fastest because it has better thermal conductivity compared to plastic foam or porcelain. This means that glass can absorb and dissipate heat more efficiently, leading to faster cooling of hot water when poured into a glass cup.
Hot water will cool if placed in a cool area. Or pouring hot water back and forth between two vessels (pans, jugs, etc). Blowing on a hot cup of tea is a common method.
the water molecules are getting cold
A styrofoam cup can help to retain heat, but it is not as effective as materials like ceramic or insulated metal. Hot water in a styrofoam cup will cool down faster compared to using a better insulated material.
The cup of boiling water will lose heat to the surroundings and cool down, while the cup of ice water will gain heat from the surroundings and warm up. Eventually, both cups of water will reach the same temperature as they exchange heat until thermal equilibrium is reached.
Warm it and add yogurt or some cream about half a cup with some water.
I think the hot water bubble flies fastest than cold water bubble.
I don't think that is possible. How can "hot" make "cool" water "cold"? (also, 'hot ice' is boiling water)

try covering the glass, so the heat particles stay inside the cup, and the hot water stays hot.
That depends on how hot the water is in the cup. Use the thermometer to measure it and see.
The plastic cups I can get have thin walls. This means the water without ice stays as water because any temperature changes to the water will not last very long. Insulated cups have thick walls so they will cool liquids cool and hot liquids hot
