by putting thermometer in water
Beer boil at a higher temperature than tap water because contain many solutes.
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.
Because you need to measure the temperature of water, not the air.
about 100 degrees Celsius
Salt in a water solution will LOWER the Freezing Point of the resultant solution. Therefore the Saltwater will have to be cooled to a lower temperature. All other things being equal, that should take longer than the plain tap water.
No, it isn't faster, tap water freezes just at the same temperature as tap water
The temperature of tap water is typically around 10-20 degrees Celsius.
Salt water can be any temperature you like, so depending on your tap water's temperature it's either yes or no.
after 30 seconds the temperature of the water is 19 degrees.
Beer boil at a higher temperature than tap water because contain many solutes.
To adjust the water temperature, turn the hot tap for warmer water and the cold tap for cooler water until you reach the desired temperature.
To adjust the temperature of the water coming out of the hot and cold water tap, you can turn the handles on the tap. Turning the handle towards the hot side will increase the temperature, while turning it towards the cold side will decrease the temperature. Experiment with different combinations of hot and cold to find the desired temperature.
This depends on many factors: temperature, pressure, geometry of the container, water surface in contact with the atmosphere, etc.
It depends on the temperature of the tap water.
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.
You can adjust the temperature of lukewarm water from the cold tap by mixing it with hot water until it reaches the desired warmth.
