What is the difference between desirable change and undesirable change?
Desirable changes are those changes which we want to occur. These changes are useful to us. For example ripening of fruits, germination of seeds, change in season. Undesirable changes are those changes which we do not want to take place are called undesirable changes.
What are desirable and undesirable changes one example?
question_answer Answers(5) Desirable changes are those that are beneficial[useful]. Milk changing into curd,a seed germinating and forming a new plant and bees changing nectar into honey are some examples of desirable change. Undesirable changes are those that are not beneficial[useful].
What are the fast changes?
The changes that are completed in short or very short duration of time are called fast changes. Examples of slow changes: Rusting of iron, as it takes many days. Some of the fast changes are spontaneous, meaning that they occur in a second or even less amount of time.
Can a change be both desirable and undesirable?
Hey mate, here is your answer : Yes, there are changes that are of desirable and undesirable. Desirable changes are the changes which are useful to us while undesirable changes ate the change which are harmful to us.

What are some examples of very fast changes?
Some changes are fast and immediately observable, such as earthquakes, volcanoes, flooding, and landslides. Other changes are slower and occur over a longer period of time, such as weathering and erosion. These gradual processes shape landforms with water, ice, wind, living organisms, and gravity.

Are all physical changes reversible?
Physical changes can further be classified as reversible or irreversible. Physical changes that involve a change of state are all reversible. Other changes of state include vaporization (liquid to gas),freezing (liquid to solid), and condensation (gas to liquid). Dissolving is also a reversible physical change.
What are natural changes?

How an undesirable change can be prevented?
With example we can learn many preventing methods.. To prevent rusting of iron we can coat it by zinc and also we can paint on the iron surface. To prevent oxidation of foods we should add some chemical preservatives in it and we can also pack them in air tight containers. Hope it helps you!May 27, 2020
