A Graphical Method Of Estimating Heat Capacities Of Hydrocarbons, Pu-Ying Liu

Masters Theses

"Heat capacity arises because the individual particles comprising a substance are able to move and thus take up kinetic energy and usually also potential energy as the temperature rises. In many substances electrons do not absorb energy until very high temperatures are reached. Thus most heat capacity effects are interpreted in terms of the motion of the atoms neglecting electronic transitions. The total internal energy of a material is, therefore, equal to the sum of the energies due to translational and rotational motion of the molecules and to the vibrational motion of the atoms making up the molecules...The objective of …
