This update to Berscheid 1985 reviews two decades of additional theoretical and empirical developments pertaining to interpersonal attraction and close relationships, and is an especially useful primer for undergraduate and graduate students interested in the area.
A funnel is a pipe with a wide, often conical mouth and a narrow stem. It is used to channel liquid or fine-grained substances into containers with a small opening. Without a funnel, much spillage would occur. A filter funnel is a funnel shaped filter that is used to separate solids from liquids. By passing the mixture of solid and liquid parts through a filter, which is either a piece of filter paper or a glass frit, the solids remain in the filter funnel and the liquid is passed into a collection flask below. A Buchner funnel is typical kind of filter funnel. <br /><br /><b>See the Web Links to the left for more information about filter funnels.</b><br /> A <b>funnel</b> is a pipe with a wide, often conical mouth and a narrow stem.

1. Prepare a filter cone: 2. Gravity filtration with a filter cone: With filtrations using a simple filter cone, the solvent may form a seal between the filter and the funnel and between the funnel and the lip of the receiving flask.When a seal forms, the filtration stops because the displaced air has no possibility of escaping.he major advantage of a fluted filter is that it increases the speed of filtration for two reasons: first, it increases the surface area of the filter paper through which the solvent seeps; second, it allows air to enter the flask along its sides to permit rapid pressure equalization.
