Vapour pressure
In an enclosed container that is not completely full,
refrigerant evaporates as vapour at the surface in a quantity
sufficient to form an equilibrium between vapour and liquid.
This equilibrium develops under pressure and is often called
vapour pressure. ...
Wear in middle of tyre
This wear pattern is found on the driven wheels of
high-performance vehicles that are frequently driven long
