Question

17) An Aluminium alloy rod has length of 10.000 cm at 20.000degrees celsius and a length of 10.015 cm at the boiling point ofwater. a) what is the length of the rod at the freezing pointof water? b) What is the temperature if the length of the rod is 10.009cm? 17) An Aluminium alloy rod has length of 10.000 cm at 20.000degrees celsius and a length of 10.015 cm at the boiling point ofwater. a) what is the length of the rod at the freezing pointof water? b) What is the temperature if the length of the rod is 10.009cm?

Explanation / Answer

Given : a ) The coefficent of linear expansionof Alluminium ( ) = 23 * 10-6 C-1 Boiling point of water ( T ) = 100oC Change in length ( L ) = 10.015 - 10.000 cm =0.015 cm = 0.015 * 10-2 m Change in temperature ( T ) = 100oC -20o C = 80o C L = LT    L = L / T        = ------- cm b ) T = L / L Where L = 10.009 cm      T = ----o C Solve it I hope it helps you Boiling point of water ( T ) = 100oC Change in length ( L ) = 10.015 - 10.000 cm =0.015 cm = 0.015 * 10-2 m Change in temperature ( T ) = 100oC -20o C = 80o C L = LT    L = L / T        = ------- cm b ) T = L / L Where L = 10.009 cm      T = ----o C Solve it I hope it helps you
