Hot: Exothermic.
Cold: Endothermic
!WARNING PHYSICS FOLLOW!
Exothermic is where something has excess energy, which it then converts into heat and/or light energy, such as a fire.
Endothermic is where something sort of... has the reverse of too much energy. When you use an aerosol can, for example, the gas is let out at a very low boiling point, which uses up a load of energy and the can gets cold.

∙ 13y agodissolution of sugar in water leads to a decrease in the randomness or entropy of a solution, so delta s value is negative and its an exothermic process that leads to evolution of energy

∙ 13y agoNo it isn't it is a physical change because it can be reversed once the water is evaporated sugar is still there.

Is making Sugar into sugar syrup a physical change or chemical change?
Unless you overdo it and carmelize it, it is a physical change. A typical process is to dissolve a large amount of sugar into hot water (physical change - the sugar is still sugar and the water is still water; they do not react. If the sugar-water is not syrupy enough, you can boil off some of the water (still a physical change). If you overdo it though, you will begin to caramelize the sugar. If the sugar is sucrose, it breaks down into fructose and sucrose along with a host of other side reactions that condense, isomerize, dehydrate, fragment, polymerize, and otherwise chemically change the original sugar. Caramelization is definitely a chemical change, but it is not necessary to make syrup.
When Sugar dissolves in hot water a physical or chemical change?
Dissolving sugar in water is a physical change. If you let the water evaporate, the sugar will be left behind. Evaporation is a physical process, not chemical.
Is dissolving sugar into water a chemical or a physical change?
It is a physical change.
Is dissolving sugar in water and then letting it evaporate a chemical or physical change?
chemical
Why mixing of sugar into water is chemical change?
First and for most, sugar mixing in water is not a chemical change. It is a physical change (Something which can be gotten back) Water and sugar, once mixed, can both be seperated by heated the liquid. The water evaporates, thus the sugar is left behind. Hope i helped. Chao!

Is dissolving sugar in water a physical changes?
Yes, dissolving sugar in water is a physical change. If you let the water evaporate, you the sugar will be left behind. Evaporation is a physical process, not chemical.-No, It is a Chemical change.
When sugar is dissolving is that a chemical or physical change?
The change is physical because the change is reversible. Evaporate the water and you are left with the sugar, no new substances are produced; the sugar stays sugar and the water, water.
Is dissolving sugar into water a chemical or a physical change?
It is a physical change.
Is a cube of surgar dissolving in water a physical or chemical change?
This is a physical change the chemical composition of the sugar does not change
Is dissolving sugar in water and then letting it evaporate a chemical or physical change?
chemical
Is mixing sugar in water a physical change or a chemical change?
ANSWER:A physical change. Nothing new is made from the solution and they both can be separated later by using heat to evaporate the water, leaving the sugar behind.
Is sugar dissolving a chemical or phyical change?
Sugar dissolving in water is a chemical change because sugar is Sucrose which in aqueous solution is broken down into Glucose and Fructose.
