From the perspective of energy efficiency an ideal cooking utensil should not absorb a large part of the thermal energy it receives from the stove. It also should not change its size as it is heated. In terms of the specific heat S and coefficient of thermal expansion a, which choice below satisfies these requirements? Both S and a should be large. Both S and a should have small values. Small S but large a. Large S but small a.
As shown in the figure, a chamber with a moveable piston and containing a monatomic ideal gas in an initial state A undergoes an isovolumetric, then an isothermal, and finally an isobaric process to complete the cycle. P (atm) LV (L) When the gas is in the initial state, the volume is 3.00 L, the pressure is 5.00 atm, and the temperature is 200 K. The gas is first warmed at constant volume to a pressure of 4 times the initial value (state B). The gas is then allowed to expand isothermally to some new volume (state C). Finally it is compressed isobarically to its initial state. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.)
