Primary sources means that it is original article or book created by an individual or sometimes a group of people. What types of primary sources are available? It might be surprising to know that a novel is a primary source. Other types of primary sources are paintings created by the artist. If it were a photocopy of the painting, then it would be a secondary source. Some other primary sources are letters, films, short stories, plays, poems, photographs, court cases, journal articles, newspaper events, and speeches. For instance, a speech by President Bush would be a primary source.
Secondary sources are sources that are written about primary sources. Secondary sources analyze, interpret, and discuss information about the primary source.

When many water molecules come into contact with one another "they get attracted to each other".
<u>Explanation:</u>
When water molecules reach into contact of each other they start attracting each other with proper orientation as the positive end of hydrogen atom of one molecule coordinate or get attached with negative end of oxygen atom of another water molecule. This link also termed as "hydrogen bond".
These attractions or hydrogen bonds showcase the ease of polarity. But the interactions are considered as weak that form between a partial positive charge of hydrogen with a more electronegative atom like oxygen, nitrogen and fluorine.
