Aheat engine having the maximum possible efficiency has an efficiency of 0.35 when operating between two heat reservoirs. if the temperature of the hot reservoir is 427°c, what is the temperature of the cold reservoir? (5 pts) a) 200 k b) 245 k c) 350 k d) 455 k e) 600 k

Option (D)

Explanation:

n = 0.35,

Temperature of hot reservoir,

T1 = 427 C = 700 K

Temperature of cold reservoir, T2 = ?

Use the formula for efficiency of Carnot cycle

n = 1 - T2 / T1

0.35 = 1 - T2 / 700

0.65 = T2 / 700

T2 = 700 × 0.65

T2 = 455 K

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
