VAPOUR CONDENSATION (‘sums and Effects

Water vapour is present to son's extent in all atmospheres and the quantity ls usually expressed ‘n tcrrm, of relative humidity. This is an expression of "the ratio of the quantity of ulster vapour present in the atmosphere to the quantltv which would sail-rate at the exist- lr-z temperature’ As the temper- ature decreases. the ainolirit of water vapour that may be contain- ed in the air also decreases. Thus air may become saturated 1y mere- lv lowering ‘l5 temperature and when the rclaiiv-w humidity be- comes 100 percent further ‘owe-ring of the temperature or the addition of water vapour will cause condo»- satlon to occur. The simple illustra- tion shows a 2nd surface in the example is a QlaSS of lcz water. that is: below the saturation tem- perature. This is apparent frotrl the formation of water, or de-iv. on the surface. _

water vapour ls an invisible gas, and like any other gas exert: a pressure. This pres- sure is measured in. in- ches or millimeters immi of mercury. T's: greater the amount of water vapour in the air, the greater is the water vapour pressure Whenever we have ud- Jacént areas with different water va- pour. pressures therv will be a tendency w flow in the diter:

It was, believed Anna Stern was de- tained for questioning only. and that she was on the list of wanted Palestine terrorists.

Most of the people of the all- Jewish city of el Aviv came swarming from their houses at 3 p. m.. when the British au'hori- lies ended the four-day .-urfew which hsd kept them virtual pris- oncrs while troops carried out the most intensive search for arms and terrorists in the history of Palestine.

As the curfew lifted the cookie ran out._Bicycles and automob es raced through the stects. long queues formed at the shops able to open first, and crowds gather- ed a ice plants. where the hot and thirsty began carrying away huge ice cakes.

During the dragnet. in which every house was searched and every perscn questioned, the

British authorities announced tho discovery of an arms cache in the Jewish ryna o ue and another arsenal in ltd en rooms of u boys school. .

Several hundred persona were arrested in the search for mem- bers of gsn s raid by Britain to be res orlslbe for the bombing of tile K g David hotel, which left la toil of ill persons dead or miss- ng.
