A calorimeter containing 200.0 mL of water was calibrated by carrying out a reaction which released 15.6 kJ of heat. If the temperature rose 3.25 degrees celcius then the heat capacity of the calorimeter inclusing the water is?
Calculate the pressure of dry oxygen. If the total pressure of oxygen generated over water is measured to be 638 torr and the temperature is 22 degress celcius?
Assume that the specific heat and density of the resulting solution are equal to those of water [4.18 and 1.00 ] and that no heat is lost to the calorimeter itself, nor to the surroundings.
