Question

The length of a metal rod at 0°c is 1.5m. Determine the temperature of the rod when its length has increased by 1.5mm. Linear expansivity of the rod is 5×10^-6°c-1

Answer 1

Answer:

∆L = L alpha ∆T

Answer 2

Answer:Tf=200°c

Explanation:♢T=alphaLi♢T

1.5×10^-3=5×10^-6×1.5 (Tf-0°c)

0.0015m=0.0000075°cM (Tf-0°c)

0.0015m=0.0000075°cMTf

0.0015m÷0.0000075°cM

Tf=200°c
