Two cylindrical rods are made of the same material and have the same length but one is hollow and other is solid. Both are heated to same increase in temperature. Which rod expands more?

From my understanding of linear thermal expansion, linear thermal expansion only depends on the expansion coefficient, the length of the material, and the change in temperature. Shouldn't the rods expand equally?

  • Physics -

    yes. They expand equally

  • Physics -

    As we know both rods have same value of coefficient ,temperature and length so there will be same expansion in both
