Answer 1

Option d

Explanation:

Efficiency of Carnot engine is given by

n = 1 - T2 /T1 = T1 - T2 /T1 _[i]

Given,

T1 = temperature of reservoir

T1 = 100 + 273 = 373 K

T2 = temperature of sink

T2 = -23 + 273 = 250 K

Substituting in Eq [i], we get

∴ n = 373 - 250 / 373 = 123 / 373

n = 100 + 23 / 373 !

Answer 2

Answer:

$\purple{100 + 23 \div 373}$

♥️This is the answer..♥️
