(i)
Clockwise moments = Anticlockwise moment.
2.0g x = 1.5g x 30
2x = 45
x = 22.5cm
(ii)
Down force: M x 22.5
= 20 x 1.5
M = 30/22.5 = 1.33Kg
Upthrust = 0.67Kg.
Therefore weight of water displaced = 6.7N

In an experiment to determine the specific latent heat of vaporization of water, steam at 1000c was passed into water contained in a well-lagged copper calorimeter. The following measurements were made:
Mass of calorimeter = 50g
Initial mass of water = 70g
Final mass of calorimeter + water + condensed steam = 123g
Final temperature of mixture = 300C
(Specific heat capacity of water = 4200 J kg -1K and specific heat capacity for copper = 390 J kg -1 K-1)
Determine the:
i) Mass of condensed steam
ii) Heat gained by the calorimeter and water
iii) Given that L is the specific latent heat of evaporation of steam
