    Accurate Formulas on Thermal Expansion

    in my previous post, I already used the value for L. L0=t(100)/(1+100α)? L0=100.24(100)/(1+100α) α=2.4*10^-5 L0=10048.0576 ? Is there a list of α of a certain material at different temperatures? if there is one, please show me. Another thing, please show me your reference material. is it a...

    Accurate Formulas on Thermal Expansion

    According to this site (http://www.wisegeek.com/what-is-the-highest-possible-temperature.htm), the highest possible temperature is 1.41679 x 1032 Kelvin. If we are going to use T0≥ 41666 2/3, then T≥0 if ΔT=-41666 2/3. The final temperature is now possible to be achieved (T≥0). Can you...

    Accurate Formulas on Thermal Expansion

    There is another question: If L=L0(1+α∆T) then it is possible for L to be zero? 0=L0(1+α∆T) Suppose L0 is not equal to zero. 0=1+α∆T ∆T= -1/α α is a very small number. for example, aluminum again. α = 2.4x10-5. then ∆T=-41666 2/3. It is a very low temperature and I'm not sure if...

    Accurate Formulas on Thermal Expansion

    1.Homework Statement . Can someone give me more accurate mathematical models on thermal expansion? for example, linear expansion. 2.Relevant equations L=L0(1+α∆T) this equation is not accurate. for example. When an object 100m long at 0oC (example: aluminum, α=2.4x10-5) is heated to...
