1.	State whether pressure applied on any part of a confined liquid is transmitted instantaneously to different parts of the liquid. Also state whether Pascal's law is applicable.
Answer» Solution :The pressure APPLIED on any part of a confined liquid does not reach different points of the liquid at once. The applied pressure is transmitted through compression and rarefaction within the liquid, and hence, with the VELOCITY of sound. During the transmission of pressure, Pascal.s LAW is inapplicable. Pascal.s law is VALID once the system comes to an equilibrium.
