Pickles are cucumbers preserved in a brine solution containing dill, alum, and salt. cucumbers shrink to a fraction of their normal size in the pickle jar. this happens because of the relative salt content of the pickling solution, which is a(n) solution.

hypertonic solution

Explanation:

Hypertonic solution -

It is the solution, with more amount of solute than the solvent , is known as hypertonic solution.

Now, is some substance is immersed in such solution , the substance gets shrinked , because , the solvent from the substance moves out of it and moves to the hypertonic solution.

Hence, the pickles gets shrinked up , as they put in a hypertonic solution.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
