Is it true that rice flakes and rice grains can be separated by winnowing?
A
True
B
False
Solution:
The above statement is true.Farmers use a process known as winnowing to remove rice flakes from grains. In this process, heavier and lighter components of a mixture are separated by the help of wind or blowing air. Coffee beans are also removed from sugar using this process. In this process, grains are allowed to fall from a certain height. Since flakes are lighter than grains, they are removed easily by air blow.
