why suger dissolve faster in hot milk than in cold milk?

Answer 1

good obervation!

well the reason is that when anything dissolves in something, that anything has it molecular bonds broken and interrupted by the solvent molecules. now to break the bonds of the solute(which dissolves) we need energy. this energy is provided by the solvent molecules.

now when anything is hot it has more energy associated with its molecules. hence hot milk has more energy too. so.....when it has more energy itself, it can provide the sugar molecules with more energy, hence its bonds can be broken faster, hence it dissolves faster.

hope ur satisfied.

Answer 2

Since the milk is hot that means there is more energy or heat, more energy means things happen faster which is why the sugar dissolves faster.

Answer 3

A solid dissolving in a liquid is the result of the liquid molecules surrounding and tearing apart the bonds of the molecule: this is called "solvation".

As you know, molecules with higher energy vibrate more than those with less energy. And this vibration translates into activity: hotter molecules are more active. In this case, the hotter water molecules in the milk are more active and hence solvate more sugar molecules than cold water molecules (of milk).

Answer 4

the molecule in the hot milk are moving faster and leaving more space for the sugar to disolve

Answer 5

Sugar is more soluble in hot water than in cold water. And milk is mostly water.

Answer 6

sugar dissolves in anything hot faster, it helps it melt

Answer 7

It's arguable and there are basically many potential answers to the question

Answer 8

This has been answered many times before

Answer 9

because of the heat
