Can any ideal gas power cycle have a thermal efficiency greater than 55 percent when using thermal energy reservoirs at 627∘C at
Yanka [14]

Answer:

Since the maximum thermal efficiency is higher than 55 percent, there can be a power cycle with these reservoir temperature with an efficiency higher than 55 percent.

Explanation:

The maximum thermal efficiency is determined from the given temperature

nth Carnot = 1- TL/TH

Where TL= 17+273= 290k

TH= 627*273= 900K.

nth Carnot = 1- 290/900 = 0.68

0.68*100 = 68 percent

Two Icecubes sat in a freezer in the kitchen. One was so bold to claim he could survive walking across the stove. As he made his way to the stove, he noticed he was leaving a wet trail, "no matter" he thought and continued his path. He touched the stove and in an instant was no longer an ice cube. He was a puddle, but not for long. He then started to float and became steam.


Thus he went from solid to liquid to gas.
