Question

state three factors on which depend the linear expansion of a metal rod on heating​

Answer 1

Answer:

length

temperature

nature

Explanation:Factors on which increase in length of a rod depend when heated are:  (1) Length of rod L. Increase in length is directly proportional to original length.  (2) Temperature of rod. It is directly proportional to increase in temperature.  (3) Nature of material of rod.  If L1 is the original length of the rod at t 1 °C and on heating to t2 °C its length becomes L 2.  ∴ Increase in length of rod = ( L 2 – L 1 ) and increase in temperature ( t2 – t1 )  ∴ [L2 – L1] ∝ L1(t2 – t1 )  But the increase in length of rod does not depend on whether the rod is solid or hollow.Read more on Sarthaks.com - https://www.sarthaks.com/156426/state-three-factors-on-which-depend-the-linear-expansion-of-a-metal-rod-on-heating
