Why are most physical changes reversable?
Most physical changes are reversible because they involve only changes in the physical state or appearance of a substance, rather than its chemical composition. Reversible changes usually involve processes like melting, freezing, dissolving, or changes in shape, which can be easily reversed by applying the appropriate conditions to change the substance back to its original state.
Are physical properties of hydrogen peroxide except?
Physical properties of hydrogen peroxide include being a colorless liquid, having a slightly sharp odor, and being miscible with water.
Does hydrogen have a texture?
Hydrogen is a gas and thus does not have texture .
What is the type of matter change in which matter stays the same and no new substances are formed?
A physical change is a type of matter change in which the substance's chemical composition remains the same, and no new substances are formed. Examples of physical changes include changes in state (solid to liquid), changes in shape, or changes in size.
Is hydrogen burns in chlorine gas chemical or physical change?
When you combust hydrogen in air, the hydrogen will combine with oxygen to form water. Therefore, the hydrogen and oxygen are undergoing a chemical change to become bonded together producing H2O: 2H2 + O2 → 2H2O + Heat
What are some physical changes of hydrogen?

Types of changes the hydrogen undergoes in a physical change?
Hydrogen gas become a liquid at very low temperature; and after we can obtain solid hydrogen.
Which is not a physical change associated with aging?
Changes in memory and cognitive function are not physical changes associated with aging. These changes are more related to cognitive decline and are often considered a normal part of aging, but not strictly physical changes.
When Hydrogen sulfide is boiling is it a chemical or physical change?
Boiling hydrogen sulfide is a physical change, as it is a reversible process where the substance changes from a liquid to a gas due to the absorption of thermal energy. The chemical composition of hydrogen sulfide remains the same during boiling.
Is hydrogen burning a physical or chemical change?
The burning of hydrogen is a chemical change because it involves the rearrangement of the atoms in the hydrogen molecule to form water. This process also releases energy in the form of heat and light.
Are state changes chemical or physical changes?
Physical Changes
What is marijuana physical changes?
what is marijuana physical changes
Example of physical change and a chemical change?
when water changes to water vapour by heating is an example of physical change. when water is divided into oxygen and hydrogen by passing electricity is an example of chemical change.
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
What is hydrogen physical state at room temperature?
Hydrogen's physical state at room temperature is a gas.
Is hydrogen chemical or physical property?
Hydrogen is neither a chemical or physical property...it is a chemical element.
Are reversible changes and physical changes the same?
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.
