Question

what is line spacing? what is its default value​

Answer 1

Answer:

The default line spacing in Word is 1.15. By default, paragraphs are followed by a blank line and headings have a space above them.

Answer 2

Line spacing determines the amount of vertical space between lines of text in a paragraph. By default, lines are single-spaced, meaning that the spacing accommodates the largest font in that line, plus a small amount of extra space. Paragraph spacing determines the amount of space above or below a paragraph.
