Heat An important concept for understanding how heat is measured is the concept of  heat  capacity .    Heat Capacity:  amount of heat needed to raise an object's temperature by 1 degree  Kelvin. More specifically we define    Molar Heat Capacity:  amount of heat required to raise the temperature of  one mole  of  a substance by one degree Kelvin.    Specific Heat Capacity:  amount of heat required to raise the temperature of  one  gram  of a substance by one degree Kelvin. The heat capacity can vary quite a bit, particularly for gasses, depending on whether the  pressure or volume is held constant as heat is added. Therefore, we further distinguish  the heat capacities with the following symbols:    C V :  Molar Heat Capacity at constant volume.    C P :  Molar Heat Capacity at constant pressure.    C S :  Specific Heat Capacity at constant pressure. Since most processes discussed in this course are carried out at a constant 1 atmosphere  of pressure, we will emphasize  C S  and  C P . If we have
