General Chemistry Questions & Answers A flow of electrons from one place to another - CORRECT ANSWER - Conductivity A liquid with a very tiny molecule will be less viscous due to its mobility - CORRECT ANSWER - Liquid water molecules A U-shaped tube with a moving column of liquid - CORRECT ANSWER - Manometer Ability of a liquid to flow in a narrow tube. - CORRECT ANSWER - Capillary Action Amorphous solids from the greek word - CORRECT ANSWER - "without form" Amount of heat given up or released when 1 gram of water change 1 gram of ice. - CORRECT ANSWER - Heat of freezing Amount of mass that exists in a certain volume - CORRECT ANSWER - Density An energy has absorbed to change 1 gram of liquid to gas at it's boiling point. - CORRECT ANSWER - Heat of Vaporization An energy that required to increase the surface area of a liquid - CORRECT ANSWER - Surface tension are completely soluble in each other - CORRECT ANSWER - Miscible Are forces between molecules of a liquid whether dispersion or dipole-dipole - CORRECT ANSWER - Cohesion Been characterized by structural rigidty and are closely packed together - CORRECT ANSWER - Solid Can insects be an example for surface tension? - CORRECT ANSWER - YES Combination of two or more metals called alloys - CORRECT ANSWER - Solid solutions Consist of solute and solvent - CORRECT ANSWER - Solution Does liquid has the ability to flow? - CORRECT ANSWER - yes Exerted by a vapor in equilibrium with its liquid state. Also the liquid molecules escape into the gas phase. - CORRECT ANSWER - Vapor Pressure Have a regular shape and they usually have flat surfaces and sharp angles. - CORRECT ANSWER - Crystalline Solids Have the ability of a liquid to resist from flowing. Also related to the movement of the molecules in the liquid - CORRECT ANSWER - Viscosity If a solution is placed on one side of a membrane and pure solvent is placed on the other side. It is called Osmosis - CORRECT ANSWER - Osmotic Pressure
