about 7.3 degrees Celsius
It depends on the temperature of the tap water.
around 54 degrees Fahrenheit
after 30 seconds the temperature of the water is 19 degrees.
Because you need to measure the temperature of water, not the air.
Heat generally tends to flow from higher temperature to lower temperatures. In this case, the cup of milk is hotter than the bowl of tab water. Hence the temperature of water increases, and the temperature of milk decreases. This process continues till both the temperatures are equal.
55
Maybe around 25ºC, depending on several factors.
Depends on where you live.
It depends on the temperature of the tap water.
Cold tap water is not itself misty. Rather, the cold temperature condenses water vapour in the air onto a conducting surface, such as a glass, a pipe, or a porcelain toilet tank.
around 54 degrees Fahrenheit
about 100 degrees Celsius
I would say around 20 degrees celsius
Tap water temperature as "cold" is its normal temperature, depending on what your water source is. Underground water usually from wells/reservoirs is about 55 degrees, where as some parts of the country water comes from above ground lakes/reservoirs, and there the temperature will vary. Its warmer in the summer and can get really really cold in the winter as the above ground water temperature drops.
This tells you the temperature of the water, H for hot and C for cold.
If you stick a thermometer under the running water, you will see for yourself. Otherwise, you could use a temperature laser gun.
The sense of temperature in your fingers would help you feel that.
