Question

a 500g sample o metal with a specific heat value of 0.119cal/g was heated to 212degrees Celsius. the metal was then placed in 2000g of h2o at 24degrees Celsius. find the final temp the experiment inside a calorimeter. (a) answer using calories (b) answer using joules

Explanation / Answer

(a) heat lost by the metal is equal to heat gained by water----->500*0.119*(212-x)=2000*(x-24)*1 gives x=29.43 degrees (here specific heat of water is taken as 1 Cal/g) (b)500*0.4979*(212-x)=2000*4.186*(x-24) which gives x=29.43 degrees (here specific heat of water is taken as 4.186 J/g) and the conversion for J/g to Cal/g is 1 joule per gram = 0.239005736 calories per gram
