Why does water's freezing point make water a poor choice for the liquid in a thermometer?
Water's freezing point is 0°C, which is relatively high compared to other liquids used in thermometers. This can limit the temperature range in which the thermometer can accurately measure. Additionally, when water freezes, it expands, which can damage the thermometer.
What are two properties that make ethylene glycol an ideal antifreeze?
Well, when mixed in an ideal solution with water, it has a relatively high boiling point and low freezing point. Also, it doesn't cause rust/corrosion.
What are some problems with the use of water as a solvent for determining the molecular mass of an unknown using the freezing point depression method?
One problem is that impurities in the water can affect the accuracy of the results. Additionally, water's freezing point is 0°C, which may limit the range of compounds that can be accurately measured using the freezing point depression method. Lastly, the specific heat capacity of water is relatively high, which can make it slower for the solution to reach thermal equilibrium.
Why does water have a relatively high boiling point and heat vaporization?
Because of strong hydrogen bonding.
How do altitude affect freezing melting and boiling points of water?
As altitude increases, the air pressure decreases. This results in lower boiling points for water because there is less atmospheric pressure pushing down on the water. However, the freezing point of water is not significantly affected by altitude.
What is the boiling point of antifrezze?
This coolant has a high boiling point of 370 °F and is not corrosive, solving many of water's problems including freezing.
Does salt water freeze at a higher or lower freezing point than freshwater?
Salt water freezes at a lower freezing point than freshwater. This is due to the presence of dissolved salt particles in the water, which disrupt the formation of ice crystals and therefore require lower temperatures to freeze.
Does water have a high boiling point?
Water has a boiling point of 100 degrees celcius. This is about average compared to the boiling point of other substances.
Why does saltwater have a lower freezing point than fresh water?
Saltwater has a lower freezing point than fresh water because the presence of salt lowers the freezing point of water through a process called freezing point depression. The salt disrupts the formation of ice crystals and makes it more difficult for water molecules to arrange into a solid structure, requiring a lower temperature to freeze.
In Celsius the boiling point of water is how much higher than the freezing point?
The freezing point of water, as defined at a standard temperature and pressure (STP) is 0.0 degrees C and the boiling point is 100.0 degrees C. So it could be said that the difference is 100.0 degrees.
Why does the freezing point of water make it a poor choice for the liquid in a thermometer?
Water freezes at a fairly high temperature - 0oC/32oF. As soon as the temperature reached that point the water would freeze and the thermometer would no longer work. One would not be able to use a thermometer with water in it to measure any temperatures below 0oC/32oF.
Water makes a good coolant because it has a . a. high specific heat c. low specific heat b. high boiling point d. low freezing point?
a. high specific heat. Water's high specific heat allows it to absorb a significant amount of heat energy before its temperature increases, making it an efficient coolant that can help regulate temperatures without rapidly changing its own temperature.
