Why salt is used in hilly areas to remove ice but on the other hand it would be used ice factory for making ice?
Salt is used in hilly areas to remove ice because it lowers the freezing point of water, making it harder for ice to form. In an ice factory, salt is not used to make ice, but rather to lower the melting point of ice to create a brine solution that can be used for refrigeration purposes. Ultimately, the use of salt depends on the desired outcome in each situation.
Why is excess ice removed from water before any salt is added?
Excess ice is removed from water before adding salt because the ice will dilute the salt and interfere with the process of creating a concentrated brine solution. Removing excess ice ensures that the proper salt-to-water ratio is maintained for the desired outcome, such as when making a brine for pickling or preserving food.
Why the volume of floating ice above the brine solution is higher to compared than in fresh water?
Water is the only liquid known to expand in volume when passing from the liquid state into the solid state called ice. That's why any glass container filled with water or water juice would break if put in a freezer. So do the ice in both poles of the Earth, taking more volume to oceans than the original water volume before freezing.
Do you add salt to the ice or the ice cream ingredients?
You add salt to ice to lower the temperature of the ice/water mixture. Without the salt, the temperature would not fall below 32.F, which is not cold enough to make ice cream. The freezing point of salt water is below that temperature and thus allows the cream to partially freeze, a necessary part of making ice cream Salt causes water to freeze at a much lower temperature. Adding salt to the ice causes the temperature of the brine solution to drop dramatically, while freezing the ice cream inside the container.
Why would spraying a brine solution to a slick road kill early spring plants growing near roadside?
Spraying a brine solution on a slick road helps melt ice and improve traction for vehicles. However, the salt in the brine can run off into nearby soil, potentially harming early spring plants by increasing the soil's salinity and disrupting their growth. It's important to consider potential environmental impacts and use alternative methods where possible.

What will happen if you add salt to ice?
Adding salt to ice lowers its freezing point, causing the ice to melt. This can create a brine solution that is colder than just ice, allowing it to absorb more heat from its surroundings. This is why salt is used to melt ice on roads or to make homemade ice cream.
Why brine solution make the thing cool?
2 reasons 1. dissolving salt in water is endothermic, ie it is a chemical reaction which absorbs heat from its surroundings 2. In more extreme cooling the water can be cooled to below 0C before freezing
What does chemistry have to do with making ice cream?
Just like in chemistry, to make ice cream you need certain amounts of ingredients. You can also think of the ingredients as a solution, and if mixed improperly, you will not get a good ice cream.
What is cacl2 and how is it commonly used to melt ice on sidewalks?
Calcium chloride (CaCl2) is a chemical compound commonly used to melt ice on sidewalks. It works by lowering the freezing point of water, causing ice to melt at lower temperatures. When CaCl2 is spread on icy surfaces, it absorbs moisture from the air and creates a brine solution that helps break down the ice, making it easier to remove.
What is a control variable for how to make hot ice?
A control variable for making hot ice could be the amount of sodium acetate solution used, as keeping this constant will ensure that the only variable affecting the outcome is the temperature of the solution.
Is an ice cream is an soloution yes or no why?
Ice cream is the solution to many problems. It can make you forget your emotional drama of the day. A couple of ice cream cones can solve problems you might have making friends, since you can share the ice cream.
Why is brine a more effective de-ice solution than solid ice melt products A) It has a lower freezing pointB) It can be applied in advance to prevent ice formationC) It is more cost-effectiveD) It is less harmful to the environment?
A) It has a lower freezing point

Is old sea ice the less saline?
Yes, brine is removed from ice as it ages.
