If similar amounts of water are at differenttemperatures and are in similar containers if a similar amount of heat is applied to each simultaneously then yes
No. water cannot be at two different extreme temperatures simultaneously.
Because they have different chemical properties and boil at different temperatures
You would use distillation, in which the ethanol and water will boil at different temperatures.
No, a crockpot is not designed to boil water. It is meant for slow cooking at low temperatures.
No, it is not possible to boil water in negative temperatures because boiling occurs at 100 degrees Celsius or 212 degrees Fahrenheit, which is above freezing temperatures.
No, a crock pot is not designed to boil water. It is meant for slow cooking at low temperatures.
These liquids have different chemical composition and structure.
Because the mixed liquids have different boiling points allowing the different liquids to boil at different times!
Water boils at 212 degrees Fahrenheit.
Distillation.
No, you cannot boil water using a magnifying glass. A magnifying glass can only concentrate sunlight to create heat, but it is not powerful enough to generate the high temperatures needed to boil water.
Water boils at different temperatures depending on the altitude. At higher elevations water will boil at a lower temperature. Since water will not get hotter than it's boiling point it will take longer to cook pasta at higher altitudes.
