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 2M solution of NaCl. At the same temperature, both the beakers were placed in closed containers of the same material and the same capacity as shown in the figure.
At a given temperature, which of the following statements is correct about the vapour pressure of pure water and that of NaCl solution?
| 1. | Vapour pressure in container (A) is more than that in container (B) |
| 2. | Vapour pressure in container (A)is less than that in container (B) |
| 3. | Vapour pressure is equal in both containers |
| 4. | The vapour pressure in container (B) is twice the vapour pressure in container(A) |
Hence, vapour pressure also get reduces.
