Is something that burns easily a physical or chemical change?
If you burn something it is a chemical change, however if you melt of boil it, it is a physical change.
Why is gas pressure increasing a physical change?
The increase of pressure of a given gas is usually a result of a change in the temperature of the gas. An increase in temperature creates a corresponding increase in pressure.
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.
What is changed when matter under goes a physical change?
When a physical change occurs, the compound stays the same. For example, if you boil water, the chemical formula still remains H2O and is a physical change. However, if you were to change the chemical formula, it would be a chemical change. If H2O were split into H2 and O2 gas, it would be a chemical change.
Does a physical property boil at 450 or is that chemical?
Boiling point is a physical property that refers to the temperature at which a substance changes from a liquid to a gas. If a substance boils at 450 degrees, that is a physical property.
When you boil water are you causing a chemical or physical change?
it's a physical change!
When you boil water are you causing a chemical change or physical?
it's a physical change!

If you boil water and itb t turns into steam is that a chemical reaction?
Nope - it's a physical change. The chemical composition is still H2O
Is dissolving in water a chemical or physical property?
Dissolving in water is a physical property because it does not change the chemical composition of the substance. The molecules of the substance are simply surrounded by water molecules and dispersed throughout the solution without undergoing a chemical reaction.
When you boil water is it a chemical change or physical change?
It is a physical change, known as a phase transition (see related links below).There is no chemical change: the water molecules remain water molecules. They have simply acquired enough kinetic energy to escape the attraction of the molecules in the liquid and move (almost) freely.
When iron rusts is that a chemical or physical change?
It is a chemical change, the iron is being oxidized and forming rust. A good way to think about it is if you can undo it then it is a physical change. For example if you put salt in water, that is a physical change because you can boil off the water and get the salt back. Source: AP Chemistry
Is water a chemical or physical separation?
Water is a chemical compound composed of two hydrogen atoms and one oxygen atom, making it a chemical substance. Physical separation refers to the process of isolating components based on their physical properties, such as size or solubility, which does not apply to water itself.
Why is gas pressure increasing a physical change?
The increase of pressure of a given gas is usually a result of a change in the temperature of the gas. An increase in temperature creates a corresponding increase in pressure.

Is it a chemical change when 2 liquids form a solid?
No because water condense on the side of a cold glass and then evaporate again. Further answer Really, if a gas becomes a liquid it's a physical change because the gas has changed its phase from gas to liquid. It's not related to water particularly.
