Each element is unique in terms of reactivity. Most elements react readily in high temperatures, but some react quicker in the cold. The same tendency is observed in respect to pressure, with most elements reacting as pressure increases. However, some others react as pressure decreases. In terms of internal factors, a higher surface area correlates with greater reactivity because reagents have a greater chance of making contact with the substance.
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space. Solid at Different Temperatures. Mass of the object remains the same, however. Solids, liquids and gases all expand when heat is added. When heat leaves all substances, the molecules vibrate slower. The atoms can get closer which results in the matter contracting. Again, the mass is not changed.
