When the temperature of a certain solid, rectangular object increases by Delta T, the length of one side of the object increases by 0.010% = 1.0 10^-4 of the original length. The increase in volume of the object due to this temperature increase is A. 0.01% = 1.0 10^-4 of the original volume. B. (0.010)^3 % = 0.0000010% = 1.0 10^-4 of the original volume. C.

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.
