Statement I : The rate of evaporation slows down as the water vapour increases in the air 

C) 1 – 3 – 4 – 2 – 5

We have given, The vapour pressure of pure water at 25°C = 18mm Hg. After addition of non-electrolyte, the vapour pressure of water = 17.32 mm Hg. Then, lowering in vapour pressure = (18...

A) full quantity of liquid evaporates

all answer d is right

opt B saucer  this is because rate of evaporation depends on factors like wind speed, temperature, and surface area. the sauser has a larger surface area and hence water evaporates faster.

A) Both A and R are true

i. True  ii. False Nonmetallic character decreases down a group.

Correct option is B) decreases

Correct option is B) decreases
