Q22Multiple choice
Two beakers of capacity 500 mL were taken. One of these beakers, labelled as “A”, was filled with 400 mL water whereas the beaker labelled “B” was filled with 400 mL of 2 M solution of NaCl. At the same temperature both the beakers were placed in closed containers of same material and same Fig. 2.2 capacity as shown in Fig. 2.2. At a given temperature, which of the following statement is correct about the vapour pressure of pure water and that of NaCl solution.
This question refers to a figure in the original PDF.
- (i)vapour pressure in container (A) is more than that in container (B).
- (ii)vapour pressure in container (A) is less than that in container (B).
- (iii)vapour pressure is equal in both the containers.
- (iv)vapour pressure in container (B) is twice the vapour pressure in container (A).
Show answer
(i) vapour pressure in container (A) is more than that in container (B).
