What is the specific heat of the liquid
A flask contains 22.5 g of an unknown liquid, initially at 14.0oC. After 2.34 kJ of heat are added to the liquid, its final temperature is 56.3oC. What is the specific heat of the liquid?

A 34.9-g sample of an unknown metal, initially at 232.8oC, is immersed in a 17.0-g sample of water (specific heat = 4.184 J g-1 oC-1), initially at 15.4oC, in an insulated cup. Once equilibrium is reached, the final temperature of the water-metal
The temperature rose by 0.910K. In a separate experiment in the same calorimeter, the combustion of 0.825g of benzoic acid, for which the internal energy of combustion is -3251kJ mol-1, gave a temperature rise of 1.940K. Calculate the internal ene
