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))`

A copper rod of 88cm and an aluminimum rod of unknown length have their increase in length independent of increase in temperature. The length of aluminium rod is: (alpha_(Cu) =1.7 xx 10^(-5) K^(-1) and alpha_(Al)= 2.2 xx 10^(-5) K^(-1))

A copper rod of 88 cm and an aluminium rod af unknown length have their increase in length independent of increase in temperature. The length of aluminum rod is (a_(cu) = 1.7 xx 10^-5 K^-1 and alpha_(Al)=2.2 xx 10^-5 K^-1)

Find the ratio of the lengths of an iron rod and an aluminium rod for which the difference in the lengths in independent of temperature. Coefficients of linear expansion of iron and aluminium are 12 xx10^(-6) 0^C^(-1) and 23 xx 10^(-6) 0^C(-1) respectively.

Find the icrease in temperature of aluminium rod if it s length is to be increased by 1% . ( alpha for alumunium = 25xx10^(-6)//^(@)C)
