Question

write a note on linear expansion.​

Answer 1

Answer:

Linear Expansion means expansion in length due to increase in temperature. ... It is defined as degree of linear expansion divided by the change in temperature. If the solid is in the form of long rod, then for small change in temperature, ΔT, the fractional change in length, Δl/l, is directly proportional to ΔT.
