Short answer question (10*1=10)
1.) What is a solute? Give an example.
Answer: A solute is a substance that can be dissolved in a solution. An example of a solute is salt.
2.) What is threshing process?
Answer: Threshing is the process of separating stalks from grains by beating.
3.) Name one method to separate solid liquid mixtures.
Answer: Evaporation is a method to separate solid liquid mixtures.
4.) What is miscible liquid?
Answer: Miscible liquid are the liquids that can be mixed with each other. Example: water and milk
5.) Why oil floats on water?
Answer: Oil floats on water because oil’s density is lesser than water.
6.) What is a solution?
Answer: A solution is a homogeneous mixture of two or more solutes mixed with solvent.
7.) Explain evaporation.
Answer: Evaporation is the process of liquid transforming into vapor. Example: water turns into water vapor due to evaporation.
8.) Name two solids that can be separated by evaporation?
Answer: Two solids that can be separated by evaporation is salt and sugar.
