Question

How does the speed of sound in air vary with temperature?

ICSE Class 9 Physics Chapter Propagation of Sound

Answer 1

Sound is also a form of kinetic energy. kinetic energy become faster when temperature increases. then molecules start vibrating faster then speed of sound wave increase.

Answer 2

when the temperature increases the speed of sound also increases as in high temperature particles will be set in motion so sound can move easily , the particles will have more kinetic energy

when the temperature decreases the speed of sound also decreases as in low temperature the kinetic energy of particles will be low
