FAQs on Important Questions for CBSE Class 6 Science Chapter 6 - Changes around Us
1. What is a change according to Chapter 6 of Class 6 Science?
Change refers to an action that takes place in the form of a transformation. In this process, one thing becomes or forms something different as compared to its original state. For example, the melting of ice. We can see that when the ice melts, it turns into water. Therefore, this means that it changes from a solid form to a liquid form. This is a similar case of butter. Change happens around us all the time in different forms of change.
2. What are the different types of changes discussed in Chapter 6 of Class 6 Science?
Our environment around us constantly changes. There are so many different ways to bring about changes. Some of these include:
Slow Changes: These types of changes occur slowly during a period of time. For example, a girl becoming a woman.
Fast Changes: These types of changes occur quickly. For example, the melting of butter on a hot pan
Periodic Changes
Non-periodic Changes
Reversible Changes
Irreversible Changes
These are the different types of changes that we see around us.
3. What would have happened to the cement bags if kept in waterlogged roads according to the Chapter 6 of Class 6 Science?
When cement bags are kept in water logged roads then a chemical change occurs. A Chemical change refers to the change where the properties of a substance changes with absorption or evolution of heat. In the case of the cement bags, if these bags have been kept in the waterlogged roads, then the cement starts to react with water. A substance begins to form with other evolution and property of heat. Therefore, this would put the cement to waste.
4. Can the change in the length of the candle be reversed according to Chapter 6 of Class 6 Science?
Reversible Change refers to the change that can be reversed. However, in this situation the length of the candle cannot be reversed. When the wax is heated on a pan, it changes its form from solid to liquid. However, on heating the wax in a pan, the wax can be changed from liquid form to solid form upon cooling. Therefore, the length of the candle cannot be reversed but the wax of the candle can be reversed from a liquid form to a solid form.
