It would depend what the black pot was made of. Assuming ceramic and both pots have the same surface area, then the silver pot would cool quicker; silver is a better heat conductor than most ceramics.
This is because of newtons law of cooling, the rate that the water cools is proportional to the difference between the temperature of the water and the temperature of the surroundings. So, as the water is hotter it cools faster, as it cools down the rate of cooling decreases.
black absorbs heat, giving it more heat to melt the ice
Hot vapors are rising from the tea. When you blow these vapors away more can rise faster to replace them. Thus more hot vapor (and thus more heat) can leave the tea while you are blowing than when you are not and the tea cools faster.
the hottter the temperature the faster salt dissolves
Hot Water cools,though kept in a closed container,because of its surroundings.Heat escapes into the environment till the temperature of water(system) and surroundings become the same. Its simply the transfer and exchange of energy.
increased surface area
simply because, the color it self black absorbs heat at a faster and larger rate... you ever notice how on a hot day you can see the tar on your street emit heat , thats because black absorbs the heat.. its the reason why solar panels are black and not white
If you pour it in a saucer, it will spread out and there is less surface area and it cools faster.
yes, hot water just cools down cold water will turn into ice which will take longer
The open windows help to expel the hot air trapped inside when they are closed.
A fan cools in hot weather.

Yes ,the higher the temperature gradient between the hot water and room temperature, the faster it cools. However, that does not mean that hot water will freeze faster than cold water (a common urban legend). If you have water at 50°C in a room at 20°C, it will cool from 50° to 40° faster than it will cool from 40° to 30°.
Hot fluid has a higher ability to dissolve solids like salt and sugar. This is how Rock Candy is made. You add as much sugar as possible to hot water, then when the water cools down, the sugar solidifies to everything it can. Hot water is just able to do this.
When air is warm, it rises and leaves an area of low pressure which becomes filled with sinking cold air. After a hot, sunny day, the land cools faster than the sea. What is likely to happen after a hot, sunny day on the sea shore?
a swim on a very hot day cools the body
They only get the black ring if you do not refresh after cooking, as soon as the eggs are boiled pour off the hot water and put the eggs under a cold running tap for a few minutes, this quickly cools the eggs and prevents the black ring.
