Answers
Answer:
Answer:
(a) A mixture of milk and water can be separated by filtration.
This statement is false. A mixture of milk and water can't be separated by the process of filtration because milk is soluble in water.
(b) A mixture of powdered salt and sugar can be separated by the process of winnowing.
This statement is false. A mixute of powdered salt and sugar can't be separated by the process of winnowing because the particles of slat and sugar are in similar size and weight.
\huge\bf{Extra\:Information :}ExtraInformation:
Mixtures can be separated into pure substance by applying appropriate separation techniques.
Methods of separation are given below :
1. Filtration - Filtration is the process of separating solid state from any liquid by filter. The filter only allows liquid substances but not any solid state.
2. Distillation - Distillation is the process of separating mixture of two substances (one liquid and one solid) by boiling.
3. Sublimation - Sublimation process can be done in two solid substances. The sublimation is the process in which solid state directly changes into gaseous state without going through liquid state.
