What else can I help you with?
Which has a higher freezing point a 20 percent salt solution or pure water?
Pure water has a higher freezing point than 20% salt water.
What are the differences of the boiling and freezing points of pure water?
100 Degrees Celcius
Is the freezing point of a mixture of water and salt higher lower or the same of pure water or none?
lower
What three standard points define the common temperature scales?
Absolute zero, melting/freezing point of pure water, and boiling point of pure water.
What will freeze faster plane water are salt water?
Adding salt to water lowers its freezing point by an amount that is dependent on the salt concentration. A saturated solution, for instance, will have a freezing point of about -20ºC compared with 0ºC for pure water. In any case, pure water will freeze earlier than salt water, because pure water has a higher freezing point.
Which would melt faster ginger ale or water?
The freezing point of pure water is higher, 0 oC.
Which is colder frozen water or frozen salt water at melting points?
The freezing point of salted water is lower compared with the freezing point of pure water. So when melting frozen salt water is colder.
How is the Fahrenheit scale defined?
The Fahrenheit scale is defined by setting the freezing point of pure water at 32 degrees and the boiling point of pure water at 212 degrees, with 180 equal divisions (degrees) between these two points.
What physical standards are Fahrenheit and Celsius temperature scales linked to?
Fahrenheit scale is linked to the freezing and boiling points of water, defining 32°F as the freezing point and 212°F as the boiling point at sea level. Celsius scale is linked to the freezing and boiling points of water, defining 0°C as the freezing point and 100°C as the boiling point at sea level.
How do the melting and boiling points of water differ from those of a sugar water solution?
The melting and boiling points of water are higher than those of a sugar water solution because the presence of sugar disrupts the hydrogen bonding between water molecules. This disruption lowers the melting and boiling points of the solution compared to pure water.
How many Fahrenheit deegres separate the freezing and boiling points of water?
Pure water freezes at 32ºF and boils at 212ºF ...212 - 32 = 180º
What are the freezing points of fresh and salt water?
The freezing point of pure water, at atmospheric pressure is 0 deg C. That of salt water depends on which salt and the concentration of the solution. The lowest temperature that can be obtained is -21 deg C.
