When sugar burns in a pot, it undergoes a chemical change known as combustion. The heat causes the sugar molecules to break down and react with oxygen in the air, forming new substances such as carbon dioxide and water vapor. This reaction releases energy in the form of heat and light.

Is adding hot water to pot noodles chemical or physical?
Adding hot water to pot noodles is a physical change. The hot water causes the noodles to absorb the water and soften, changing their physical state without altering their chemical composition.
Describe the physical and chemical changes that occur when a pot of water is boiled over a campfire?
When a pot of water is boiled over a campfire, the physical change is the water transitioning from a liquid to a gas (steam) as it reaches its boiling point. The chemical change involves the breaking of hydrogen bonds between water molecules to form steam, but the chemical composition of water (H2O) remains the same during the process.
Is adding water to pot noodles a physical change?
Adding water to pot noodles does not result in a physical change, as the water is simply being mixed with dry ingredients to rehydrate them. A physical change involves a change in the appearance or state of a substance without altering its chemical composition.
Do the bubbles in a pot of boiling water for noodles indicate chemical change?
No, the bubbles in boiling water for noodles do not indicate a chemical change. The bubbles are formed due to the physical process of water reaching its boiling point and turning into steam bubbles. This is a physical change, as only the state of the water molecules is changing, not their chemical composition.
When water is boiled in a pot it bubbles Is this the result of a chemical reaction Explain why or why not?
The bubbling of water when boiled is not the result of a chemical reaction. It is due to the conversion of liquid water to water vapor, which forms bubbles as it rises to the surface. This process is physical in nature, involving the phase change from liquid to gas.
Is adding hot water to pot noodles a physical change?
Adding hot water to pot noodle is a physical change because the chemical nature of water remain unchanged.
Is adding hot water to pot noodles chemical or physical?
Adding hot water to pot noodles is a physical change. The hot water causes the noodles to absorb the water and soften, changing their physical state without altering their chemical composition.
Clay pot fired in a kiln physical or chemical?
The firing of a clay pot in a kiln involves both physical and chemical processes. The physical process is the application of heat to the clay, causing it to harden and form a solid structure. The chemical process involves the transformation of the clay minerals into a more stable crystalline structure through processes like dehydration and recrystallization.
If an ice cube is placed in a pot that is heated what will happen after it has melted is it a chemical or physical change?
When ice melts and becomes a liquid it is a physical change. When the liquid boils and becomes gaseous it is a physical change. It is a chemical change when the molecular structure has been changed in some way, here it has not.
Why is it physical change if the steel wool turned the black pot shiny silver?
Physical change: the steel wool only changes the black pot's shape and in doing so reveals another color in the pot or the color of the substance that the pot is made from; it would still be the same thing but there would be all the parts of the pot, just it would be in different pieces.

What is an example of matter that has gone through a physical change only?
A good example of a simple Physical Change occurs in a tea pot. The hot, liquid water boils and goes off as steam. Steam is still water (no chemical change,) but is now a gas.
Is boil chemical?
It is NOT a chemical reaction. Boiling is a physical reaction. When heat is applied to water in a pot, the hydrogen and oxygen molecules begin to get excited; they bounce around everywhere. The heat traps the oxygen molecules in bubbles, which go to the sides of the pot (following the path of least resistance). These bubbles then come to the surface, releasing oxygen and steam. Boiling is simply a phase change from a liquid to a gas.
When a pot holder is being used to hold a pot of boiling water it is being used as?
a safety precaution to prevent burns or injuries from the hot pot. It acts as a barrier between the heat of the pot and the person holding it.
