Elasticity of Solids Deformation: Changes in shape or size of an object through the application of external forces. Elasticity: Property which allows a material to regain its shape after being distorted. Elastic Limit: The maximum amounts by which an object or a material can be stretched and still regain its original shape after the distorting forces are removed. An object or a material which returns to its original length or size after being distorted suffers elastic deformation

1-hexanol D-4 #1‚2 C=O‚ -CH Cannot conclude Preparative Gas Chromatography was used to separate volatile compounds‚ which can then be identified. The injected sample becomes vaporized and was carried through the mobile column. It is usually carried by an inert gas. The gases were moved through the stationary column. The polarity of the components to the column would cause the separation of the components. Opposite to a TLC‚ if the stationary column was very polar‚ the more polar components will fall behind
