We feel cool when we sit near the fan, this is because A. Fan gives cool air. B. Fan cools surrounding air. C. Air vapourises the sweat on our body. D. We feel cool when air touches the body.

The correct answer is: C. Air vapourises the sweat on our body.

When we sit near a fan, the fan

blows air over our skin. This air helps to evaporate the sweat on our skin, which cools us down. Sweat is a liquid that is produced by our bodies to help regulate our temperature. When sweat evaporates, it takes heat away from our bodies, which makes us feel cooler.

The other options are incorrect because:

• Option A is incorrect because the fan does not actually cool the air. The fan simply blows air over our skin, which helps to evaporate the sweat on our skin.
• Option B is incorrect because the fan does not actually cool the surrounding air. The fan simply blows air over our skin, which helps to evaporate the sweat on our skin.
• Option D is incorrect because we feel cool when air touches our body because the air helps to evaporate the sweat on our skin.
