Question

What is the difference between 'which' and 'that'?

Pls answer urgently.

Answer 1

There is no difference in meaning. There is a difference in use. Relative clauses—the sort of clause you use, “which is blue” / “that is blue”, which tells us something more about the noun referred to by which or that—are of two sorts: restrictive and nonrestrictive.

Answer 2

which means command of questions and that means which point out particular thing
