What is the difference between a chemical and a physcial change?
chemical change is easily reversible whilst physical is not reversible
What is a non reversible change?
A reversible change is a change you can make, then put back, however a non-reversible change is a change you can make, then it will be stuck like that
What is the difference between chemical change and physical change?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
What is the difference between a physical and chemical change?
A physical change is reversible, a chemical change is not.
How is boiling of egg a chemical change?
because you are changing its form and look
Is boiling water to make tea a reversible change or a chemical reaction?
it's a reversible change
Is boiling potatoes a chemical change?
Boiling potatoes is a physical change, not a chemical change. The heat causes the starch in the potatoes to gelatinize and the cells to rupture, but the chemical composition of the potatoes remains the same.
Is tea a reversible change or non-reversible change?
It is not a reversible change. During boiling some components are extracted with hot water from the crushed dried leaves. It is impossible to restore the original leaves.
Is boiling water a reversible change?
Yes, the boiling of water can be easily reversed by simply cooling the water vapor.
Which of them is a reversible change coffee dissolving Water boinling Chocolate melting wood burning?
Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
Is making crisps from cooking oil and potatoes a reversible change or chemical reaction?
Most cooking processes are chemical reactions. Generally, the reactions are non reversible and once cooked, food cannot be returned to an uncooked state. So, frying potatoes causes a non reversible chemical reaction. The question is not as precise as it might be. Changes can be physical or chemical. They can also be reversible or non reversible but it is important to note that many chemical changes are reversible just as many physical changes are reversible.
How is the boiling of water and the cooling of water vapor reversible?
Because the water stays water, its only a phase change.
Is boiling water to make tea a chemical reaction or a reversible change?
Boiling water to make tea is a reversible physical change. When water boils, it changes from liquid to gas, but it can easily be reversed by cooling the gas back into liquid form. No new substances are formed during this process, indicating that it is a physical change, not a chemical reaction.
Is boiling water irreversible?
From a thermodynamics standpoint, it depends how the process is carried out. If the system (the water) and the surroundings remain close to equilibrium during the entire process then the water boils reversibly. So if the change in temperature is approximately zero throughout the process and the process takes an infinitely long amount of time to carry out you can reversibly boil water.If you were asking whether water vapor can turn back into liquid water, then yes the process of turning water into water vapor is reversible.
Is boiling carrots a chemical change?
no it is a physical change
Is boiling water to make steam a permanent change?
No, boiling water to make steam is a physical change, as it can be reversed by cooling the steam back into water. The water molecules remain the same substance throughout the process.
What are the effects of adding heat and are they reversible?
Adding heat to a substance can cause it to change in various ways, such as melting, boiling, or burning. These changes are usually reversible if the substance is not permanently altered by the heat.
