Why molar specific heat at const. Pressure is greater than molar specific heat at const.volume? |
| Answer» Well the case is simple molar specific heat is amount of heat required to raise the temp of a substance 1mole to 1 celcius so at constant volume particles have no more space to move around so their kinetic energy increases hence increase in temp would be like temp of kinetic energy of particles due to not expanding + heat given. but in case of constant pressure volume will increase causing cooling effect which also needs to be neutralized by heat so total temp would be like heat given to neutralize cooling effect of expanding + heat to rise temp to 1 celcius hence this molar specific heat is greater clearly | |
