Physics
An electric heater raises the temperature of 120g of water in a thin light vessel through 10K in 2mins, when placed in 70g of water contained in a metal vessel of mass 0.55kg the temperature rises through 9K in the same time. Calculate from the above: a)the heat supplied in ...

Physics
what mass of ice at -14'c will be needed to cool 200cm3 of an orange drink (essentially water) from 25'c to 10'c! (specific latent heat of fusion of ice =336000) (specific heat capacity of ice = 2100) (specific heat capacity of water = 4200)

Physics
calculate the specific heat capacity of the materials for which the heat supply, mass, and temperature rises are given below: i)25200J, 0.3Kg,20K ii)8000J, 500g, from 20'C to 60'C iii)9450J, 150g, from 15'C to 45'C
