The enthalpy of combustion of benzoic acid (C6 H5 COOH) is commonly used as the standard for  calibrating constant-volume bomb calorimeters;  its value has been accurately determined to be  −3226.7 kJ/mol. When 1.9862 g of benzoic acid are  burned in a calorimeter, the temperature rises from  21.84°C to 25.67°C. What is the heat capacity of the  bomb? (Assume that the quantity of water surrounding  the bomb is exactly 2000 g.)

Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
