Classify the following into osmosis/diffusion:
(a) Swelling up of a raisin on keeping in water.
(b) Spreading of the virus through sneezing.
(c) Earthworm dying on coming in contact with common salt.
(d) Shrinking of grapes kept in thick sugar syrup.
(e) Preserving pickles in salt.
(f) Spreading of the smell of cake being baked throughout the house.
(g) Aquatic animals using oxygen dissolved in water during respiration

Osmosis:
- Osmosis is the movement of water molecules over a semi-permeable membrane from a high-concentration solution to a low-concentration solution.
- It is a generic process in which gases are also involved.
Diffusion:
- Diffusion is the mixing of one substance with another caused by the motion or movement of its particles.
- It is one of the material's qualities.
- The diffusion of one component into another continues until a homogeneous combination is established.
(a) Osmosis is the enlargement of a raisin after keeping it in water.
- Raisin has a higher concentration of solutes than outside water.
- As a result, water travels into the raisin, causing it to enlarge.
(b) Diffusion is the propagation of the virus caused by sneezing.
- The virus enters the air as small droplets as a result of sneezing.
- They remain suspended in the air for a long period and travel around due to diffusion.
(c) Osmosis is the death of an earthworm when it comes into touch with ordinary salt.
Earthworms die when they come into contact with common salt because their skin dries up due to water loss.
(d) Osmosis is the shrinking of grapes held in thick sugar syrup.
- This is because water moves down the concentration gradient from higher to lower concentration.
- This causes grapes to shrink.
(e) Osmosis is the process by which pickles are preserved in salt.
Salt aids in the removal of water from cells and the preservation of pickles.
(f) Diffusion is the spread of the smell of baking cake throughout the house.
The scent is produced by the cake particles spreading by diffusion.
(g) Diffusion is the answer for aquatic species that use oxygen dissolved in water during breathing.
- Diffusion allows aquatic creatures to use the oxygen dissolved in water.
- Temperature, the number of salts in the water, and pressure all influence the amount of dissolved oxygen.
