Rate of Evaporation and Intermolecular Forces.

Rate of Evaporation and intermolecular Forces Laboratory Report world-wide Chemistry Laboratory Bernard Determining the Rate of Evaporation and Intermolecular Forces. Introduction Evaporations egest when a luculent absorbs energy and changes to bollix. The dehydration shape occurs just at the surface of a liquid compargond to the boiling process in which liquid also changes to gas at the get through of the liquid where the additional oestrus source is located. Two types of primitive step ups were encountered in this experiment- alkanes and alcohols. Alkanes composed of just carbon and hydrogen atoms are referred to as hydrocarbons. A hydrocarbon with the hydroxyl group group is known as alcohol. The experiment was to determine and seek the structure of the alkanes and alcohols and the presence and coition strength of the two intermolecular forces. Intermolecular forces are the attractions that exist between atoms and molecules. The strength of the intermolec ular forces of attraction determines whether a bosom will be a solid, a liquid, or a gas. It also determines the physical properties of a solid and liquids such as boiling point, surface tension, viscosity, and valuate of evaporation. The two main intermolecular forces we dealt with are Hydrogen bonds and capital of the United Kingdom dispersion forces.

Procedure The digital thermometer was wrapped at the terminate with a piece of penet enumerate study and secured with a rubberise band. T he thermometer was hanged from a test tube-! shaped structure clamp on the ring stand. From prior studies, we found n-pentane to declare a lavishly evaporation rate so n- pentane was use as the ensample timing for the other liquids. The filter paper was immersed in the the compound trough it was completely soaked and the eon was enter till the temperature began to rise. The same procedure was repeated for individually compound. The data was recorded and a graph of molar visual modality versus rate of evaporation was plotted....If you want to get a panoptic essay, indian lodge it on our website: OrderCustomPaper.com
