Problem :

Reproduce a drawing of a Carnot cycle.

Problem :

On your Carnot cycle drawing, shade the region that represents the heat consumed by the system at the higher temperature.

Problem :

On the same drawing, now shade in a distinct manner the region that represents the heat that is unable to be converted to work.

Solution for Problem 3 >>

Heat Unusable by the Device

Problem :

Suppose we have a heat engine in which σ _H - σ _L = N ₀ , where N ₀ is Avogadro's number. Suppose further that T _l = 300K and T _h = 600K . Give the work done per cycle.

Problem :
