1At what temperature of 0^C steel rod copper rod have length of 80.1cm and 99.9cm respectively. At what temperature will the 2 rods have the same length. Coefficients of linear expansion (per °C) copper rod----.000017 steel rod-------.000012 2.The length of a brass bar increase from 4.001m into 4.0030 m. find the final temperature of the bar if the initial temperature was 0 Celsius. Coefficients of linear expansion (per °C) brass----- .000019
I would bypass IKEA for a good thermal expansion efficient coffee table. Try an upmarket store of expanding knowledge instead. In the meantime, you could ask for a thermos flask to tea you over.
I had a negative experience with one. I was a sleep and was awakened by a loud pop and pain on my big toe, I looked down and I had black on my toe and on the blanket.
using them while pregnant has been linked to an increase in birth defects. To eliminate this, turn on the blanket to warm up the bed, but then turn it off before you crawl in.
Thermal Expansion Problems And Solutions
1) Copper: L Loc(1 + λc T) Steel: L Los(1 + λs T) At same length L: Loc(1 + λc T) Los(1 + λs T) T (Los - Loc)/(λcLoc - λsLos) (80.1 - 99.9)/(.000017x 99.9 - .000012x80.1) -26862°C The result is totally absurd (no such a temperature can exist), and there is no wonder because the difference in length is too big, and no change in temperature can compensate for it. 2) L Lo(1 + λ T), so T (L - Lo)/λ (4.0030 - 4.001)/.000019 105°C
