6 Class science notes-Ch-6-Changes Around Us

A change can bring different kinds of effect on the things around us. Some of the effects brought are permanent in nature which cannot be reversed. Some effects are brought into position, shape, size or state of the things; these effects are temporary in nature.
Changes caused by heating
Some objects simply get hot, but no other change takes place – When we drink hot milk or coffee, from a cup, we feel that the cup is hot. Although it doesn’t change the state of the cup take place.
Some objects get hot and expand – The metal gets heated and increase in size, on cooling the metal got contracted and regained its original size.
Some objects get hot and burn – If we will burn a candle it will heat and melt away, this change is irreversible in nature as we cannot get the candle back in shape.
Some objects change their state – When ice is heated it changes into water, when water is heated it changes into steam. These changes can be easily reversed hence they are called reversible changes.
Changes caused by Pressure or Force
When you fill air into a balloon, by applying pressure to your lungs, the shape and size of the balloon changes. If we continue filling more air, then a stage will come when the balloon bursts and its shape changes again. The tube within the tyre changes its shape and fits completely.
