What is changed when matter undergoes a physical change give an example to explain your answer?
When matter undergoes a physical change, its state or appearance may change, but its chemical composition remains the same. For example, when water is heated and turns into steam, its physical state changes from liquid to gas, but it is still composed of H2O molecules.
What changes of matter occur in respiration?
A change is said to be physical if no new substances are formed. Physical changes are temporary and can easily be reversed to give back the substances in their previous form. Freezing of water is an example of a physical change. A change is said to be chemical if new substances with different properties are formed. Chemical changes are permanent and cannot be reversed to give back the substances in their previous form. Burning of paper is an example of a chemical change.
Is separating sand from gravel a physical or chemical change?
It's Physical your just separating your not mixing chemicals and what not(:
Is rain turning to sleet a physical or chemical change?
A physical change. It came from water and is still water.Physical - the water changes from a gas,water vapour, to a liquid, rain.
Why would dissolving salt in water be considered physical change?
This is a physical change. This is a an interesting example - it is considered to be physical because the salt can be recovered through evaporation. However the salt in solution is separated into ions which are solvated by water molecules- this could be argued as a chemical change.- as there are albeit weak interactions between the water and the ions. Some salts dissolve and hydrolysis occurs, a "genuine" chemical reaction with water. An example is sodium acetate, (a salt of a weak acid), this dissolves to give a basic solution- this would be a chemical change. This is reversible - you can evaporate the water and get the salt back.
Can you give you an example of a physical change?
water turning into ice
Give 3 example of physical change?
There are quite a few examples of physical change including melting ice. You can also consider freezing water and boiling water a physical change.

Give one example of physical change that could be easily reversed?
Change of state from a liquid to a solid and back again.
How does physical change differ from a chmical change?
A physical change alters the form of the substance but does not change it into anything new. An example of a physical change is the boiling, freezing, melting, condensation of water. The result changes still give you water. A chemical change must make a new substance with new properties. An example of a chemical change is the burning of wood. The new substances made during complete combustion are ash, carbon dioxide, and water.
Give an example of a chemical or physical process that illustrates the lae of conservation of mass?
you can change a mass of something if you take part of the product out of it

What something in an experiment that can change?
The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.
