we know that water bubbles are formed when external pressure becomes equal to the internal pressure so room temperature is 20 digree to 25 digree and internal pressure deos not equal to external pressure at this temperature so it is clear that vapor bubbles deos not formed in water at room temperature and standard pressure where standard pressure is 760 torr.
external pressure is pressure that other things exert on you
External
Pressure is the external force acting over a unit surface area of a material. Stress is an internal force acting over a cross sectional area within the material. It may also be thought of as the internal resistive response of a material to the applied external pressure. They both have the units of force / area. think it as- suppose we have a cubical solid mass. we apply external force of few magnitude on it and this force will try to deform the cube. at the same instant an internal force will generate within the cube that will try to maintain the shape and size of the cube i.e. this internal force will work against the applied external force. this induced force within the cube is stress.
breathing in through your nose is internal, breathing out through your mouth is external.
Pressure Shaft is designed to resist Internal as well as External Pressure, but the Penstock is designed to resist Internal Pressure only. - Saravanan.S

The possible internal and external influences on your food choices include; External: advertising peer pressure aroma ease of access Internal: general hunger perceived deficiency (yearning for a particular food or flavor)
In the sea, the external water pressure is greater than the ear's internal air pressure, so it implodes. In space, the external vacuum is less pressure than the ear's internal air pressure, so it explodes (or is 'sucked' into space.)
Is a salmon internal or external?
Our bodies have an internal pressure equal to that of the atmosphere (101000 pascals). Once the external pressure on you body exceeds this internal pressure enough your body will implode. This external pressure can be provided by water. Depending on how you go about going that far below water and the specific tolerances of your body a deadly depth can be from 500 to 1200 feet.
Octopus internal pressure equals external pressure and there is no crushing.
