It is not a ball but rather a pineapple
Putting a lid on a cup helps to keep it hot by reducing heat loss through evaporation. The lid creates a barrier that traps the heat inside the cup, maintaining the drink's temperature. Additionally, the lid prevents heat from escaping through convection as well.
Boil it with a cup and a lid on. Boil it for 10 minutes and open the lid. The water droplets under the lid will be colourless
In a plastic cup, either with a plastic lid or a peel-off aluminum foil lid.
Yes, it does. I have a whole set with that size lid and the 1 3/4 cup casserole is included and the lid works.

EBAY
This is called a Ciborium
you drink it through the opening in the middle of lid with your lips open and tipping up the cup
A cup of tea loses heat faster without a lid because the heat energy in the tea is transferred to the surrounding air more quickly due to convection. A lid helps to trap the heat within the cup, reducing the rate of heat loss to the environment.
no it do not keep it longer
