5 hrs to freeze solid
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.
Adding salt to water will lower the freezing point, thus requiring the salt water to get colder before it will freeze - it thus takes longer to freeze because it takes additional time to cool from the normal freezing point on down to the new (colder) freezing point.
Nothing, you have a solution of antifreeze. However if you then cool the solution the freezing point will be lower than that of pure water.
Adding salt to water lowers the freezing point of the water. This is because the presence of salt disrupts the formation of ice crystals, making it harder for the water molecules to arrange into a solid structure at the same temperature as pure water.
For liquids to solidify, the temperature of the liquid must be below its freezing point. Every substance has a different freezing point. For example, water's freezing point is 0 degrees Celsius. At 1 degree, it will be a liquid. If you cool it down to -1, it will solidify.
The fastest way to cool beer is to place it in a container filled with ice and water, and then add salt to the mixture. The salt lowers the freezing point of the water, allowing the beer to cool more quickly.
Water remains water no matter what state it is in, we just call it ice when it becomes a solid. However, you can keep water a liquid below it's freezing point by super cooling it. Another cool fact is if you cool water below freezing and it is still a liquid, shake it and it will start to freeze in a matter of seconds.
No, adding salt to water does not make it cool down faster. In fact, adding salt to water lowers its freezing point, which means it will take longer to freeze but will not cool down faster.
If the substance is a liquid, cool it until it freezes. Record the temp while it is freezing, pure substances freeze at a distinct temperature, the freezing point. If it is a solid heat until it melts --- melting point = freezing point.
because it depens in the temperature of the ?
Depends on the pressure the water is under, but normal water will freeze.
That really depends what you mean by grit. If it's just powdered rock, there is no effect. If you mean rock salt, then the freezing point is reduced because the salt dissolves. The lowest freezing point achievable for salt solution is - 21.1 degrees C.
