Two identical calorimeters are each of heat capacit 12J/k, one contains 8x10-5 m3 of water and takes isose to cool from 325k to 320k and the other contains an equal volume of an unkown liquid which takes 50 sec to cool over the same lange of tempr. The dens, heat capacity of liquid over the temps range? of liquid is sookg/m? what is the average spa ( water = kg / m3, Sw = 4200 kg - 1K1)
