960 units, or 10,7^0 units ofheat was obtained from the 20 grams of steam condensing. Therefore i gram condensing gives up 537 units, and weconclude it takes 537 units to change i gram of water at 100into vapour at 100°. By more accurate methods the latentheat of steam is found to be 536. The… … Fig. 21.
