Test: Methods of Separation in Everyday Life - Question 3

Which method uses wind to separate lighter particles from heavier particles?

Detailed Solution for Test: Methods of Separation in Everyday Life - Question 3
Winnowing uses wind or blowing air to separate lighter particles from heavier particles.
Test: Methods of Separation in Everyday Life - Question 4
What technique involves using a sieve to separate particles of different sizes?
Detailed Solution for Test: Methods of Separation in Everyday Life - Question 4
Sieving involves using a sieve to separate particles based on size.
Test: Methods of Separation in Everyday Life - Question 5
Which separation method is commonly used to obtain salt from seawater?
Detailed Solution for Test: Methods of Separation in Everyday Life - Question 5
Evaporation involves heating seawater to convert it into vapor, leaving behind the salt.
Test: Methods of Separation in Everyday Life - Question 6
What process allows heavier particles to settle at the bottom of a liquid?
Detailed Solution for Test: Methods of Separation in Everyday Life - Question 6
Sedimentation allows heavier particles to settle at the bottom of a liquid.
Test: Methods of Separation in Everyday Life - Question 7
Which technique involves pouring a liquid through a filter to separate insoluble solids?
Detailed Solution for Test: Methods of Separation in Everyday Life - Question 7
Filtration involves pouring a mixture through a filter to separate insoluble solids from liquids.
Test: Methods of Separation in Everyday Life - Question 8

Which method uses agitation to separate lighter components from heavier ones in a liquid mixture?

Detailed Solution for Test: Methods of Separation in Everyday Life - Question 8

 Churning involves agitation to separate components in a liquid mixture based on their density or other physical properties. In the context of churning, lighter components, such as cream, can be separated from heavier components, such as buttermilk, by the mechanical agitation of the mixture.

Here's a quick rundown of the other methods you listed:

  1. Magnetic separation: This method uses magnets to separate magnetic materials from non-magnetic ones.
  2. Sedimentation: This process allows heavier particles to settle at the bottom of a liquid over time due to gravity.
  3. Winnowing: This technique involves separating lighter components from heavier ones by using air flow, commonly used in agriculture to separate grain from chaff.

So, for separating lighter components from heavier ones using agitation, churning is the correct choice.

Test: Methods of Separation in Everyday Life - Question 9
Which separation technique uses magnets to isolate magnetic substances?
Detailed Solution for Test: Methods of Separation in Everyday Life - Question 9
Magnetic separation uses magnets to attract and separate magnetic substances from non-magnetic ones.
Test: Methods of Separation in Everyday Life - Question 10
What is a common application of decantation in daily life?
Detailed Solution for Test: Methods of Separation in Everyday Life - Question 10
Decantation involves pouring off the clear liquid from a mixture after allowing heavier particles, such as mud, to settle at the bottom.
