Answer ( 1 )

  1. It is because when we dissolve any salt in water, its lattice breaks down into smaller units for which lattice energy is required.

    This lattice energy is obtained from the surrounding atmosphere and hence the container in which we are dissolving the salt in water gets cooler.
