Question

effect of temperature on sound velocity​

Answer 1

ᴇғғᴇᴄᴛ ᴏғ ᴛᴇᴍᴘᴇʀᴀᴛᴜʀᴇ ᴏɴ sᴏᴜɴᴅ ᴠᴇʟᴏᴄɪᴛʏ​

ᴄᴀsᴇ :— ᴡʜᴇɴ ᴀɪʀ ᴛᴇᴍᴘᴇʀᴀᴛᴜʀᴇ ɪs ʟᴏᴡ.

As the temperature of air decreases, the air molecules become more and more rigid. The vibrating capacity of the molecules reduces. Sound is a series of waves which vibrate the molecules to transmit the energy.

As the temperature is low, the molecules vibrate lesser and lesser. Due to less vibrations, the energy takes a longer period of time to get transmitted.

So, the speed of sound is low at lower temperatures.

ᴄᴀsᴇ :— ᴡʜᴇɴ ᴛᴇᴍᴘᴇʀᴀᴛᴜʀᴇ ᴏғ ᴀɪʀ ɪs ʜɪɢʜ.

The converse of the above situation is also true. The air molecules vibrate more and more due to higher temperatures. High temperature means sound waves easily travel the distance in a much shorter time.

Answer 2

Most of the people are employed in the primary sector this is because in the secondary sector ,when the development increases 6 times then the employement increases 2.5 times only.In tertiary sector, if the development increases 13 times the employement increases 5 times only...

Hope it helps!
