It is know as cryogenic decread to the decrease in the temperature of the freezing point which undergoes a dissolution with respect to that of the pure solvent.
It is observed that a higher Temperature object which is in contact with a lower temperature object will transfer heat to the lower temperature object. The objects will approach the same temperature , and in the absence of loss to other objects, they will then maintain a constant temperature. They are then said to be in thermal equilibrium.
Ice Pigging is a revolutionay method of clearing pipes that uses slush ice as an alternative to traditional pigging methods. An ice slurru is pumped into a pipe and forced along inside in order to remove sediment and other unwanted deposits to leave the pipe clean.
We have pour some water in a glass and put an ice cube inside. While the ice cube is floating over the water surface, we have put a piece of thread on the ice cube carefully. Then we dropped a pinch of salt over the thread and the ice cube. We just wait a few second, then we pulled the thread up, there it was, the ice cube had been amazingly hooked together with the thread.
