Which separation
technique will be used by a lady
for the separation of dirt from
clothes in washing machine?
Answers
Separation technique used by a lady for separating dirt from clothes in a washing machine is centrifugation.
Explanation:
Centrifugation is the technique which involves the application of centrifugal force for separating particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed.
A washing machine works under this principle. It has a rotor which helps spin the cloth, water and soap mixture. The centrifugal force thus created will separate the dirt from the clothes. Further, when spinning rapidly, the dirty water is removed from the cloth, leaving the clean cloth behind.
Answer:
Adding Washing soap and filtering out dirt
Explanation:
When greasy dirt or oil is mixed with soapy water, the soap molecules arrange themselves into tiny clusters called micelles
Soap has a chemical tendency that when it is dissolved in water that contains dirt or oily components, the hydrophobic sides of soap cling to dirt or contamination and take them out., The molecules of soap allign themselves in micelle formation where the dirt is blocked at the centre of the formation. These also don’t dissolve in water and hence are separated out
