What else can I help you with?
Does the temperature must drop 0 C for water to freeze when a solute is dissolved in the water?
A solute added to water decreases the freezing point.
What temperature does water melt?
== == Pressure has an effect on the freezing point of water, though it isn't as substantial as the effect of pressure on boiling point. We could say that these values are at standard pressure, but realistically there is no noticeable difference of water's freezing point on various altitudes on earth. But it should be noted that if there are ions dissolved in the water, the freezing point will drop significantly due to the added solute. The melting point of water is the same as the freezing point of water; 32 degrees Fahrenheit or 0 degrees Celsius.
When the air pressure is low the freezing point of water decreases or increases?
When the air pressure is low, the freezing point of water decreases. This is because lower air pressure allows water molecules to escape more easily, reducing the need for the temperature to drop in order for freezing to occur.
Water freezing in bottle when opened?
When a bottle of water is opened, the pressure inside the bottle decreases, causing the water to start freezing because of the drop in temperature. This phenomenon is known as "flash freezing" and occurs rapidly when the conditions are right, such as in very cold temperatures.
Is it true that the temperature must drop lower than 0 Celsius for water to freeze when a solute is dissolved in the water?
Yes if something is dissolved in the water then it is no longer pure water and the freezing point will change

Why does the freezing point of water drop with the addition of salt?
The "foreign" molecules of the salt get in the way of the formation of ice crystals.
What does sea salt do to ice?
Adding sea salt to ice lowers the freezing point of the ice, causing it to melt. This process is called freezing point depression, and it helps create a brine solution that can be colder than the freezing point of water, allowing the mixture to remain in a liquid state at lower temperatures.
What would cause the greatest drop in a substance's freezing point... A. Barium Chloride B. Glucose C. Lithium Fluoride?
I suppose that barium chloride cause the greatest drop of the freezing point.

What is the percenatge of salt in water to stop it freezing?
I'm not a chemist, but there should be a table that gives Freezing Point of water for various percentages of salt. My point is that EVERYTHING can be made to Freeze if you drop the Temperature to Absolute Zero. You need to be more specific to what Temp level you want to keep your water mixture.
Is a bad to put salt on an ice cube and eat it?
Yes. You could get frostbite. The reason: Salt lowers the freezing point of water. As the ice absorbs energy from its surroundings (salt water), the temperature will drop, but instead of stopping at 0°C, when water would start to freeze, the salt water will continue to drop below 0°C in temperature, because it's not at its freezing point, yet.

What is sub freezing temperature?
Sub-freezing temperatures refer to temperatures that are below the freezing point of water, which is 32 degrees Fahrenheit (0 degrees Celsius). These temperatures can cause liquids to freeze and surfaces to become icy, posing risks for travel and outdoor activities. It is important to take precautions to stay warm and protect oneself from the cold when temperatures drop below freezing.
Is it true that the temperature must drop lower than 0 Celsius for water to freeze when a solute is dissolved in the water?
Yes if something is dissolved in the water then it is no longer pure water and the freezing point will change
What temperature doe water freeze?
32oF or 0oC or 273.15 K or 32oF or 0oC or 273.15 K Pressure has an effect on the freezing point (or melting point) of water, though it isn't as substantial as the effect of pressure on boiling point. We could say that these values are at standard pressure, but realistically there is no noticeable difference of water's freezing point on various altitudes on earth. It should be noted that if there are ions dissolved in the water, the freezing point will drop significantly due to the added solute.
