It's either obey the law of conservation of mass, causing new matter to be created or it is an execption to the law of conservation of mass.
Physically it can melt and chemically sugar can combine with the oxygen in the air and burn.
a chemical reaction
No, mixing sugar and chocolate is not a chemical change. It's a physical change.
Because melting sugar turns color to form caramel. i.e. it has changed and specifically it has undergone a CHEMICAL CHANGE (Or chemical reaction). When melting ice, no chemical reaction occurs, and so it is just a PHYSICAL CHANGE.
Yes it is chemical because the sun is producing food by causing chemicals and substances
To call it an physical or chemical change, we first need to describe both of them briefly. A physical change is the one which does not change the chemical properties of a substance. A chemical change is the one which changes the chemical properties of a substance. Whether they can be recovered or not is not of importance here. So if you mean to dissolve some powder in hot water such that it does not make any reaction with water, then its a physical change. (Mixing flour or salt or sugar powder are examples) However if you put some powder in hot water which creates a reaction and the molecules of that powder are no longer the same, then it would be a chemical change. (Adding tiny sodium or potassium pieces to water are examples)
It is a chemical change
It is a physical change and only becomes a chemical change if the sugar is burnt.
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!
Yes, grinding is a physical change because the chemical composition of the substance does not change.
Thats sugar+oxygen Arent all chemical changes physical?
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.
Burning Sugar is a chemical change. Burning or oxidization is always a chemical change. The process takes in Oxygen and Sugar and outputs different compounds including water, carbon dioxide, carbon monoxide, and other carbon residue. Explanation 2: Chemical changes are changes in what things are made out of. Physical changes are like ice melting ice and liquid water are still water one is a solid but the other is liquid. steam is a gas but is still water. these changes do not change what water is.
Physical changes
the sugar does not undergo a chemical change it simply dissolves into the water. if you were to then boil the water till it dried you would get your powdered sugar back (although it would probaly be brown because of the pressence of the tea) well to be honest with you it undergoeas a chemical and a physical change because it changes its look (Physical) and it turns to nothing (Chemical)
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.
Yes, Powdering of sugar is a physical change. Grinding of sugar and it becomes a powder form hence powdering of sugar is a chemical property because it cannot be converted back into crystal form. This physical changes that are irreversible.
Sugar is a physical property.
