Experiment:
Aim:
To observe the miscible and immiscible liquids.
Things needed:
Water, oil, milk, 2 spoons, 2 glasses.
Method:
a) When milk is mixed in water, they dissolve completely. When two liquids mix together such that they dissolve completely in each other, they are called miscible liquids.
b) When oil is mixed in water, it does not dissolve. Instead, oil and water form separate layers within the container. However, when two liquids mix together such that they do not dissolve completely in each other, they are called immiscible liquids.
Observation:
We will observe that what happens after 1 hour.
Conclusion:
Milk and water are mixed but oil and water do not mix.
Water Filtration:
Q.3. Give four ways to get safe water from unsafe fresh water.
Ans: The following ways to get safe water from unsafe freshwater- Filtration Sedimentation Boiling Purifying water with chemicals.
Q.5. What are the three states of water?
Ans: The three states of water are –
a) Ice (Solid)
b) Liquid
c) Water vapour (gas)
5) How can we get safe water from pond’s water?
Ans: Water of ponds, canals and rivers has mud and dirt in it. We can get safe water from pond’s water by the following ways: By filtration through cloth or filter we can get clean water. But this clean pond water is not free from germs. We can separate clean water from dirty water by depositing sediments at the bottom of a pitcher or pot. This clean pond water is also not free from germs. By boiling both the filtered water and separated clean water we can get safe water.
