Question

What is the coefficient of thermal expansion for a substance that was originally 1.084 m long at 8.081 oC and expands to 2.974 at 99.046

Answer 1

Answer #1

The coefficient of thermal expansion is defined as

Where, L is the length of the substance at temperature t and L_0 is the length at the initial temperature t_0.

So, putting the given values,

We get the coefficient of thermal expansion as

j 1) The volume thermal expansion coefficient is defined as the fractional change in volume of a substance per unit change in temperature. Consider a closed chamber containing a monatomic ideal gas at atmospheric pressure. Consider its behavior as its temperature is increased by a small amount T, and find its volume expansion coefficient, assuming (a) isobaric and (b) adiabatic conditions. Finally, (c) discuss why these two values are different, and compare them to expansion coefficients of liquids and solids.
