'7' Calculate the change in boiling point m if water for a change of pressure 0f 1 mm. 0f mercury, being given that\" vagvolume of 1 gm. of steam at 100C21674 c.c. viz-volume of 1 gm. of water at 100C=1-04 c.c. L=latent heat of vaponisation of water==537 cals./gm. (Ans. 0'0364C) 100 C=1.013. 22. Calculate the latent heat of ice given that change of pressure of one atmosphere changes the melting point of ice by 0-0074 C and when 1 gm. of ice melts volume changes by 0.0907 c.c. (Ans. 80.8 cals)
