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.
What is changed when matter undergoes a physical change give an example to explain your answer?
The physical properties of the material are changed; example - water: ice, liquid water and water vapors have very different properties but the same chemical formula.
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.

Is separating sand from gravel a physical or chemical change?
It's Physical your just separating your not mixing chemicals and what not(:
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.

toilet plunger
Give one example of physical change that could be easily reversed?
Change of state from a liquid to a solid and back again.

Give an example of a physical change of state?
i dont know i really dont konw yes i can water turning into ice
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.
i neeed 30 phiscal change and 100 chemical change got its boi?
give me 50 physical changes and 10o chemical change
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 is different between physical and chemical change give example?
lets say you have a brick and you brake it in have. that is a physical change because it changed its apperence or physical charictaristics. a chemical change is when it changes to solid to liquid. Or liquid to gas. Like melting an ice cube is a chemical change because it was a solid now its a liquid.
