Why is food preserved by chilling or freezing?
Freezing food preserves it for later use. You can freeze meat, vegetable, fruits, prepared dishes and more. When you're ready to use it, remove it from the freezer, thaw, and heat. Freezing foods is very convenient in today's lifestyle, and prevents having to throw it out.
Should a raincoat have a high or low melting point?
A Raincoat? Like a literal raincoat? This question makes almost no sense but ok. The melting point is the temperature at which a substance transitions from solid to liquid. You, as a raincoat user, presumably prefer your raincoat in the solid phase. Therefore you would want this transition point to occur as far away from the normal range of temperatures in your area. The higher the melting point of the raincoat, the hotter it can get without getting ruined. But again, this makes 0 sense.
Why does tap water freeze before salt water?
Short Answer:As you lower temperature, pure water freezes first at exactly 0 degreesCentigrade or 32 degrees Fahrenheit. (That is part of the definition of those temperature scale.)When water has any impurity in it, the freezing temperature is lower. This is called "freezing point depression."Explanation:People say, "Pure water freezes faster than salt water," but what is more accurate is to say that salt water freezes at a lower temperature than pure water. If you cool two identical samples of water, one pure and one salty, then temperature of salt water has to be lowered further to freeze, so it takes longer.Tap water or any form of fresh water usually has such a small quantity of impurities present that the decrease in freezing temperature is a tiny fraction of a degree and not noticeable without specialized equipment.Once you get to a percent or two of impurities in water, you start to see a degree or two change in freezing temperature. The specific change depend on what impurity you put into the water, but the more you put in, the lower the freezing temperature gets.The cause of freezing point depression is a result of the disruption of the perfectly regular arrangement that water molecules want to make when they form solid crystalline water, i.e.pure ice. Basically all pure solids, want to form some kind of perfect crystalline arrangement of their constituent atoms or molecules when cooled to a low enough temperature, i.e.the freezing temperature. Such a perfectly regular arrangement is disrupted by impurities, large impurities or charged impurities being more disruptive for water. As a result of the disruption the temperature must be lowered further before the energetics and the forces between particles becomes favorable enough to form the solid.So, impurities in almost any material will cause a lowering of the temperature at which the material changes from a liquid to a solid.
How can a solid be separteed from a liquid?
1: filtration: is the easiest way to do it but only works up to a certain point. 2: evaporation: just heat your compound until the liquid starts evaproating (if you want to use it, you have to condensate it again) and when all liquid is "gone", the solid should be left.
What is the temperature of ice and water?
Maybe you asked if what is the temperature of ice. Well, since the freezing point of water is 0 degrees (ice is the result when water reach 0 degree Celsius) So, ice is 0 degree Celsius. But if you want to ask what is the temperature of the water, it just depends. The boiling point of water is 100 degree Celsius. But the temperature of water will just depend while you measure its temperature by using a thermometer in a minute or hour.
When a solute dissolves into water the freezing point does what?
When a solute is dissolved into water the freezing point will lower. In other words, if you want to freeze a solution of water and some solute, you will have to cool it beyond the freezing point of pure water.
What is the freezing and melting point in Celsius?
Assuming you are talking about water, the freezing point is 0 degrees Celsius, melting point would be anything above that, and just in case you want to know, the boiling point for water is 100 degrees celsius
What is the boiling and freezing point of degrees Celsius?
You didn't say of what substance you want to know about. I will assume that you are talking about water. The boiling and freezing point of water are 100 degrees and 0 degrees, respectively.
What is the relationship between a material freezing point and it's melting point?
It is the same thing. A melting point or freezing point is when a "material's" temperature stays the same. Then you can decide whether you want to freeze it or melt it by increasing or lowering the temperature.------Thats how my science teacher tought us.
What do lower the freezing point mean?
Lowering the freezing point simply means that you have done something to whatever you want to freeze (or don't want to freeze), so that a lower temperature is needed to make it freeze. For instance, adding salt to water lowers it's freezing point (which is normally 32 degrees Fahrenheit). That's why salting a sidewalk or roadway makes the ice melt under normal winter conditions. You can also lower the freezing point of water by adding alcohol or propylene glycol (automotive antifreeze).
How could you change the boiling and freezing temperature of water?
If you want to limit yourself to water only, you could change the pressure. That would greatly change the boiling point and slightly change the freezing point. If you don't care about limiting yourself to pure water, you can dissolve a salt or other substance in the water to lower the freezing point and raising the boiling point.

What affect does salt to freezing point hypothesis indipendent and dependent variable?
An "hypothesis" doesn't have independent and dependent variables until you design an experiment to test it. If you want to test the effect that salt in solution has on the freezing point of the solution, then the independent variable is the presence, absence, or concentration of the salt. The dependent variable is the freezing temperature you measure in each condition.
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.
What is the normal freezing point of water in Kelvin?
273.15K is the melting point of water in kelvin That's not correct; water boils at 100 degrees Celsius, to go from C to K, you add 273 to the Celsius temperature... 100+273 = 373 degrees K
What is the freezing point of chocolate?
