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

Why does the pitch of a note produced by a wooden open end organ pipe become shaper when the temperature increases ? Explain in detail.

When the pitch of note produced by a harmonium is lowered, then the wavelength of the note:

When a gas is suddenly compressed, its temperature rises. Why?

At 16^(@)C , two open end organ pipes, when sounded together produce 51 beats in 3 second will be produced, if the temperture rises to 88^(@)C ? Neglect the increase in length of the pipes.

Organ pipes are musical instruments which are used for producing musical sound by blowing air into the pipe. Organ pipes are of two types: closed organ pipes are closed at one end and open at the other. Open organ pipes are open at both ends. The study shows that the overall musical sound produced by an open organ piipe is richer than the musical sound produced by a closed organ pipe. Read the above passage and answer the following questions: (i) Why the overall musical sound produced by an open organ pipe is richer than the musical sound produced by a closed organ pipe ? (ii) What does this study imply in day to day life ?

The frequency of the fundamental note produced by a closed organ pipe is n. If the diameter of the pipe is doubled, then the frequency of the fundamental note produced by it will be (Neglect end correction)

Why is the sound produced at one end of a metallic pipe heard twice at the other end ?

Why is the sound produced by an organ pipe open at both ends is better than that of an organ pipe closed at one end ?

At 16^@C , two open organ pipes , when sounded together, produce 34 beats in 2 seconds. How many beats per second will be produced, if the temperature rises to 51^@C ? Neglect the increase in the length of the pipes.

Why is note produces by an open organ pipe sweeter that that produced by a closed organ pipe of same length?
