- 5 Please help thank youA gas expands from 2.2 L to 3.6 L against a constant external pressure of 1.6 atm. What is the work done? A. -227 J B. 227 J C. 2.24 J D. -2.24 JFrom 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.
