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.
Explain why the coefficient of thermal expansion for a solid vanishes at T=0.

2. Coefficient of thermal expansion (CTE), ay by volume is approximately three times of linear CTE, at ay of fused silica and silicon carbide is 1.65 x 10-6/°C and 12.9 x 10-6/°C, respectively. Calculate the % increase of diameter of each sphere made from fused silica and silicon carbide with 20mm of diameter after being heated from 25°C to 1000°C. Which one has a higher increase of diameter? What is your conclusion?

In this solution, just trying to understand why the coefficient of thermal expansion of steel is multiplied by 3. I understand volume is cubic. Don't need answer. Thx The average coefficient of volume expansion for carbon tetrachloride is 5.81 ✕ 10−4 (°C)−1. If a 55.0-gal steel container is filled completely with carbon tetrachloride when the temperature is 10.0°C, how much will spill over when the temperature rises to 26.5°C? (Assume the coefficient of thermal expansion of steel is 11 ✕...

Now the friends use data obtained in the simulation to identify materials A-E. They calculate and record the value of α for each material and use the table below to identify it. (Hint: The simulation rounds some of the data to two-digit accuracy, so calculate all coefficients of linear thermal expansion using AT 50.)
