The heat of combustion for phthalic acid is 19.4 kJ/g. 2 g of this is burned in a bomb calorimeter. The bomb calorimeter contains 2,250 g of water. The temperature of the calorimeter goes from 23 oC to 26.17 oC. What is the heat capacity of the empty bomb calorimeter

In physics the desire of an object to keep doing what it is doing is termed?

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
