Elements are pure substances that contain -primary substances of which all other things are composed only one type of material, such as the following: more resistant the substance is to changes in temperature. Quartz is very abundant mineral of many varieties that consists primarily of silica, or silicon dioxide (SiO2). For gases, departure from 3R per mole of atoms is generally due to two factors: (1) failure of the higher quantum-energy-spaced vibration modes in gas molecules to be excited at room temperature, and (2) loss of potential energy degree of freedom for small gas molecules, simply because most of their atoms are not bonded maximally in space to other atoms, as happens in many solids. The heat capacity of the ethanol (C EtOH) depends upon how much ethanol is in the system. 24-carat is pure gold, but it is very soft.
