Short Answer TypeCalculate the enthalpy change on freezing of 1.0 mol of water at 10.0°C to ice at –10.0°C.
Heat capacity at constant pressure is greater than heat capacity at constant volume. Why?
Long Answer TypeShort Answer TypeWhenever a chemical reaction occurs, some bonds present between atoms of reacting molecules are rearranged to form products. Energy is required to break bonds while it is released during bond formation. Thus during the rearrangement of bonds in reactants and products, sometimes energy is released and sometimes it is absorbed. Therefore, there is an energy change in chemical reactions.
