The task in the image involves matching different separation processes with their correct descriptions. Below is a detailed explanation of each process and its corresponding description, along with the solution.

Separation Processes and Their Descriptions
1.
Evaporating and Condensing
-
Description: Separates liquids from solids when the liquid can be vaporized and then condensed back into a liquid.
-
Explanation: This process is used to separate a solid dissolved in a liquid by heating the mixture to evaporate the liquid, then cooling it to condense the vapor back into liquid form. The solid remains behind.
-
Match: Separates soluble solids from liquids.
2.
Decanting
-
Description: Separates two liquids that have different densities (weights).
-
Explanation: Decanting involves pouring off the upper layer of a liquid mixture where the layers do not mix (e.g., oil and water). The denser liquid stays at the bottom, and the less dense liquid is poured off.
-
Match: Separates two liquids which have different weights.
3.
Magnetism
-
Description: Separates iron and steel from non-magnetic materials.
-
Explanation: A magnet is used to attract magnetic materials like iron or steel, leaving non-magnetic materials behind.
-
Match: Separates iron and steel from non-magnetic materials.
4.
Filtering
-
Description: Separates insoluble solids from liquids.
-
Explanation: Filtering uses a filter paper or mesh to allow a liquid to pass through while retaining solid particles that are too large to pass through the pores.
-
Match: Separates insoluble solids from liquids.
5.
Sieving
-
Description: Separates different sized solids.
-
Explanation: Sieving uses a sieve with holes of specific sizes to separate larger particles from smaller ones. Larger particles remain on top of the sieve, while smaller particles pass through.
-
Match: Separates different sized solids.

Solution: Matching the Processes to Their Descriptions
-
Evaporating and Condensing → Separates soluble solids from liquids
-
Decanting → Separates two liquids which have different weights
-
Magnetism → Separates iron and steel from non-magnetic materials
-
Filtering → Separates insoluble solids from liquids
-
Sieving → Separates different sized solids
