Liquids and gases are both states of matter. Any change in state of matter is a physical change, whether it be boiling, freezing, melting, or condensing. Steam is water is the gaseous state and ice is water in the solid state. They have differnet forms, but the chemical makeup remains the same.
chemical
A change of state: Solid <-> Liquid <-> Gas A change of state is a physical change.
Physical change. The wax was solid and now it is a liquid. All phase changes are physical changes.
Boiling is a physical change because there is no change in the chemical composition of the substance.
Yes. It is the temperature at which a gas condenses into a liquid.
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. Chemical changes are changes in what things are made of, physical changes are changes of physical localization or state of matter ( liquid, solid, or gas)
No, changes of state such as this are physical changes.
The basic answer is physical.
chemical
A change of state: Solid <-> Liquid <-> Gas A change of state is a physical change.
Physical. changes of state (solid, liquid, gas) are physical changes.
It is a physical change (melting).
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that matter, to a solid.
Cooling, and changing from a liquid to a solid are physical changes, not chemical changes. The chemical composition of the paraffin does not change.
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.
These are changes of phase and physical phenomenons: - solid to liquid: melting - gas to liquid: liquefaction (or condensation)
