It lowers the temperature of the water. Instead of a minimum temp of 32 degrees it drops to something in the lower 20's. This freezes the ice cream faster. Also a great trick for quickly chilling a cooler full of warm beers. (Thanks mythbusters!!)
Polar and non-polar substances do not stay mixed with each other because they have different types of chemical bonds and interactions. Polar substances have uneven distribution of charge, while non-polar substances have an even distribution of charge. This difference in charge distribution causes them to repel each other, leading to separation and lack of mixing.
Not all substances behave the same way when mixed with water. Some substances dissolve in water to form a solution, while others may react with water to form new compounds or stay separate as a suspension or colloid. The behavior of a substance in water depends on its chemical properties and the interactions between its molecules and water molecules.
to stay hard
nothing
It would be a chemical change, because if it was a physical change it would stay the same substance, but in a chemical change you mix 2 different substances to get a new substance.
Yes. (the cream does not stay on the teeth, the coffee does)
The function of the kidneys is to purify the blood by removing waste materials. The substances that stay in the kidneys are amino acids, sodium and other nutrients in the body.
so the ice cream won't mealt and stay at a low vescosity leavel.
yes definitely unless you plan on having ice cream soup tonight!
yes
because
Substances keep there identities because they are not chemically changed so they are going to stay the same!
