Why does the pitch of a note produced by a wooden open end pipe becomes sharper when the temperature rises?

Answer:

                With rise in temperature, the velocity of sound increases. The fundamental frequency of an open organ pipe is given by\[({{v}_{1}}=\upsilon /2l)\]. Hence with an increase in the value of \[\upsilon ,{{v}_{1}}\] increases and the pitch of the note becomes sharper.
