Increase in length/(Initial length x rise in temperature)

A copper rod of 88 cm and an aluminium rod of unknown length have their increase in length independent of increase in temperature. The length of aluminium rod is (alpha cu=1.7xx10^(-5) K^(-1) " and " alpha Al=2.2xx10^(-5) K^(-1))

When two closed organ pipes at 0^@C are sounded together 20 beats are heard in 4 seconds. How many beats will be heard per second when the temperature is 100^@C. The increase in length of the pipes due to rise in temperature may be neglected.

The coefficient of linear expansion of a rod of length 1 m, at 27^@C , is varying with temperature as alpha = 2/T unit (300 K le T le 600 K) , where T is the temperature of rod in Kelvin. The increment in the length of rod if its temperature increases from 27^@C to 327^@C is

Length, Mass, Temperature are ?

If the rate of reaction increases by two times with every 10^@C rise in temperature, then if we raise the temperature by 40^@C , the new rate of the reaction will be :-

An ideal gas is initially at temperature T and volume V. Its volume is increased by DeltaV due to an increase in temperature DeltaT, pressure remaining constant. The quantity delta=(DeltaV)/(VDeltaT) varies with temperature as

Normally, solubility of a crystalline solid increases with temperature. Does it increase uniformly in all cases? Name a substance whose solubility : initially increases then decreases with rise in temperature.

If the length of a simple pendulum is increased to four times the initial length how is the time period affected?

Statement- 1 : Temperature of a rod is increased and again cooled to same initial temperature then itsfinal length is equal to original length provided there is no deformation take place. Statement- 2 : For a small temperature change , length of a rod varies as l = l_(0)(1+alphaDeltaT) provided alpha DeltaT ltlt1 . Here symbol have their usual meaning.

Calculate the increase in velocity of sound for 1^@C rise of temperature if the velocity of sound at 0^@C is 332 m//s .
