Give reason for following:. 1. We should wear cotton clothes in summer. 2. steams gives more burning effect than boiling water. 3. level of water do not increase after dissolving sugar in it.
Answers
We wear cotton clothes during summer as cotton absorbs sweat from the body, exposing to the atmosphere for easy evaporation. ... Cotton allows better air circulation which helps to absorb and removing body moisture caused by sweat via evaporation.
Steam will produce more severe burns than boiling water because steam has more heat energy than water due to its latent heat of vaporisation.
Because sugar dissolve in water and fix into empty space between molecules. The level of water doesn't change when sugar is dissolved in it as it is soluble in water it occupies space between the 2 molecules of water. Hence it's level ie it's volume doesn't increases.
hope THIS HELPS!!!
