Depends on the season and country. In the UK, tap water is around 7 degrees Celsius in the winter, but gets up to 19 or 20 in a warm Summer, maybe even higher.
At normal atmospheric pressure, i.e. near sea level, water boils at 212 F or 100 C. The fact that it is tap water, not pure water, would make very little difference.
after 30 seconds the temperature of the water is 19 degrees.
It depends on the temperature of the tap water.
Because you need to measure the temperature of water, not the air.
around 54 degrees Fahrenheit
No, it isn't faster, tap water freezes just at the same temperature as tap water
No, at pH = 8 (tap water pH) no CaCO3 will precipitate at normal tap water temperature. pH of sodium bicarbonate (baking powder) is also 8.

Salt water can be any temperature you like, so depending on your tap water's temperature it's either yes or no.
What temperature is the tap water? A little will dissolve in room temperature tap water, but if you raise the temperature of the water more sugar will dissolve. If you boil the sugar, it will break down into two simpler sugars and won't precipitate when the water is cooled.

Beer boil at a higher temperature than tap water because contain many solutes.
Depends on where you live.
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.
