A researcher wants an alarm to sound when the temperature of air in his controlled research chamber rises above `40^@C` or falls below `20^@C`.The alarm can be triggered by the output of

When the temperature of water decreses from 4^@C to 2^@C ,will the level of water rise or fall in the cylinder?

when temperature in increased by 1^@ C velocity of sound in air increaeses by

Air is pumped into an automobile tyre's tube up to pressure pf 200kPa in the morning when the air temperature is 20^(@)C. During the day the temperature rises to 40^(@)C and the tube expand by 2%. Calculate the pressure of the air in the tube at this temperature.

An air bubble of 20 cm^3 volume is at the bottom of a lake 40 m deep where the temperature is 4^@ C . The bubble rises to the surface which is at a temperature of 20 ^@ C . Take the temperature to be the same as that of the surrounding water and find its volume just before it reaches the surface.

It takes 2.0 seconds for a sound wave to travel between two fixed points when the day temperature is 10^@C . If the temperature rises to 30^@C , the sound wave travels between the same fixed parts in

Air is pumped into an automobile tyre's tube up to pressure pf 200kPa in the morning wheb the air temperature is 20^(@)C. During the day the temperature rises tp 40^(@)C and the tube expand by25. Calculate the pressure of the air in the tube at this temperature.

A column of air and a tuning fork produce 4 beats per second when sounded together. The tuning fork gives the lower note. The temperature of air is 15^(@)C . When the temperature falls to 10^(@)C , the two produce 3 beats per second. Find the frequency of the fork.
