answer the following question in 3 - 4 complete sentences.\nanswer the following questions about pencil drawing:\n- when were pencils first used?\n- what is graphite?\n- what is an hb pencil?\n- what happens when the h# is increased?

Answer

Brief Explanations:

Pencils were first used around the 16th century after a large - scale graphite deposit was discovered in England. Graphite is a form of carbon that is soft and can leave marks on paper. An HB pencil is a medium - hardness pencil, with "H" indicating hardness and "B" indicating blackness, and HB is a balance between the two. When the H# is increased, the pencil becomes harder and produces lighter, finer lines as it deposits less graphite on the paper.

Answer:

Pencils were first used around the 16th century. Graphite is a form of carbon. An HB pencil is a medium - hardness pencil. When the H# is increased, the pencil becomes harder and produces lighter lines.
