Vapor pressure means pressure exerted by the vapor of the liquid on the surface of the liquid. When liquid is cold, say water at 0Â°C at normal pressute, there will be absolutely no water vapour at its surface as all water has solidified. It will be called as low vapor pressure. When water is boiled at normal pressure, 100Â°C, all the water will begin to vaporize and all its surface will be occupied by vapour. Pressure exerted by this vapor will be same as atmospheric and called as high vapor pressure.
What hand should you wear it on? The hand and finger for the promise ring depends on the individual. Typically they are worn on the ring finger of the left hand, in the place of an engagement ring, if the wearer is not married. Many people transfer it over to the fourth finger on their right hand when they get married. Splash News.
Ring Finger of the Left Hand . A promise ring is a promise of commitment and often precedes an engagement. Therefore many couples like to wear a promise ring on what is traditionally thought of as being the wedding ring finger -- the ring finger of the left hand. When engagement rings have been exchanged, the promise ring is then worn on another finger. Tip: Remember that every finger is a different size. The ring finger of a left hand may well be a different size to the ring finger of the right hand. Therefore if a promise ring is going to be an expensive purchase, it is worth considering whether the size of the ring can be altered if it will be worn differently in the future.
