5. Name the list of whole grains.
VII. Answer in detail.
1. Discuss briefly about three states of matter.
2. Draw a flow chart to indicate the process of making fabrics from cotton ball.
The raw fibres are separated from the seeds by a process known as ginning.
2. Give two examples for food products made from wheat.
Bread and Cakes
3. What are synthetic fibres?
Synthetic fibres are made by human beings with the help of chemical process.
4.What is known as upthrust?
When an object is immersed in a liquid, the liquid exerts an upward force on the object. This is known as upthrust.
5. Name the list of whole grains.
Wheat, maize, rice, barley, beans, peas and millets are some of the whole grain
1. Discuss briefly about three states of matter.
Solid
In solids molecules are very closely arranged.
Solids are incompressible.
They have definite shape, size and volume.
Liquids
In liquids molecules are loosely packed.
Hence, liquids are negligibly compressible.
They have definite volume, but no definite shape and size.
Gas
In gases, molecules are very loosely packed.
Hence, gases are highly compressible
2. Draw a flow chart to indicate the process of making fabrics from cotton ball.
