(Solved)
A copper calorimeter of mass 60g is filed with 100g of water at 250C. Steam at a normal
temperature and pressure ( N.T.P) is passed thought the water until a temperature 450C is attained.
The final mass of calorimeter and the contents was found to be 163.5g. Calculate the specific latent
heat of vaporization ‘l’ of water (Specific heat capacity for water is 4200JKg^-1 and for copper is 378Kg^-1K^1)

(Solved)
A accelerates uniformly from it initial velocity, u, the final velocity, v in time t. The distance
traveled during this time is S. If the acceleration is denoted by the letter, a show that;
(i) V = u + at
(ii) S = ut + at2
(iii) V2 = u2 + as
