chemical change is easily reversible whilst physical is not reversible
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
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.
A physical change is reversible, a chemical change is not.
because you are changing its form and look
it's a reversible 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.
Brewing tea is a reversible change because the tea leaves can be dried and reused, and the water can be evaporated to leave behind tea solids.
Yes, the boiling of water can be easily reversed by simply cooling the water vapor.
The reversible change is coffee dissolving in water. Boiling water, melting chocolate, and burning wood are irreversible changes.
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.
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.
Because the water stays water, its only a phase change.
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.
no it is a physical 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.
At a high temperature (during boiling or frying) the composition of potatoes is modified - a chemical change.
