Yes, it is true; this technology involve chemical processes.
Yes, as well as a chemical change. It clearly changes (white, granulated sugar and liquid to burned brown sugar and liquid to a sticky [and delicious] substance). It changes from a solution to a syrup!
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.
This reaction is a chemical process.
This is a physical process.
Heating table sugar until it caramelizes causes the sugar molecules to break down and rearrange into a new compound with different properties, such as color and flavor. This process involves chemical reactions that form new compounds, making it a chemical change.

It is actually a chemical change. The butter, sugar, water and cream are cooked, resulting in a chemical change. Toffee cannot be "uncooked" back into butter and sugar. Physical changes can be undone. Chemical changes, no.

Sugar dissolving in water is a chemical change because sugar is Sucrose which in aqueous solution is broken down into Glucose and Fructose.
The process of bees creating wax from sugar is a physical change. It involves the physical transformation of the sugar molecules into wax molecules without any change in the chemical composition of the substances.
Heating table sugar until it caramelizes causes the sugar molecules to break down and rearrange into a new compound with different properties, such as color and flavor. This process involves chemical reactions that form new compounds, making it a chemical change.
Dissolution is a physical process.
No, mixing sugar and chocolate is not a chemical change. It's a physical change.
The conversion of starch in the pizza crust to sugar is a chemical change. This process, known as hydrolysis, involves the breaking down of starch molecules into sugar molecules by reacting with water.
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.
