Apower cycle operating between two reservoirs receives energy qh by heat transfer from a hot reservoir at th = 2000k and rejects energy qc by heat transfer to a cold reservoir at tc = 400k. for each of the following cases determine whether the cycle operates reversibly, irreversibly, or is impossible:
a.) qh 1200 kj wcycle 1020 kj
b.) qh 1200 kj qc 240 kj
c.) wcycle 1400 kj qc 600 kj
d.) η 40%

can you make it more obvious. i can't see it properly

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
