At 16°c, a rod is exactly 23.59 cm long on a steel ruler. both the rod and the ruler are placed in an oven at 260°c, where the rod now measures 23.83 cm on the same ruler. what is the coefficient of thermal expansion for the material of which the rod is made? the linear expansion coefficient of steel is 11 x 10-6 /c°.

Explanation:

= Original length of rod

= Coefficient of linear expansion =

Initial temperature = 16°C

Final temperature = 260°C

Change in length of a Steel is given by

Change in material rod length will be

The coefficient of thermal expansion is given by

The coefficient of thermal expansion for the material is

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!
