Real Life Examples of Physical Change
Physical changes can be observed all around us. Some of the real life examples of physical change around us is mentioned below:
Melting of Ice
When ice converts into water by giving it heat, it undergoes a physical change. There is no formation of new substances. It is a reversible change, as water can be converted to ice by cooling. The mass is also constant.
Boiling of Water
When water is exposed to heat, it starts boiling at 100 °C. At this temperature, liquid water starts converting into vapor. In this process, no new compound is formed. We can cool these water vapors and get back the liquid water.
Freezing of Water
When we freeze water in the refrigerator, it turns into ice. Ice is not a new material, but water. When we take ice out of the refrigerator, it melts by absorbing heat from the environment and again converting into liquid form.
Tearing Paper
When you tear a paper, it is also a physical change. The shape and size of paper changes but its chemical composition remains same. It is reversible process as we can make the paper again from these pieces.
Mixing Salt or Sugar in Water
When salt or sugar is dissolved in water, it is a physical change. The solution so obtained does not have a completely unique property but has property of water as well as sugar or salt depending upon what has been dissolved. Hence, no new substance gets formed in the process so it is a physical change. Also, we can separate water, sugar or salt by evaporation. Hence, it is a physical change.
Stretching Rubber
When rubber is stretched its shape and size changes but it regains that again after removing force so it is a physical change. Hence, here no new product is formed only shape is deformed temporarily. Thus stretching of rubber is a physical change.
Real Life Examples of Physical Changes
Physical Changes are the changes which can be reversed back to previous form without any disturbance. In everyday life, we see a lot of physical changes happening in surrounding such as melting of ice, dissolving of sugar in water etc. Physical change is a change in which no new substance forms. The chemical composition of a substance remains the same, just there is a change in its physical properties.
We have compiled the real life examples of Physical Changes in the article below.
