Question

What is the coefficient of performance (β) of a Carnot refrigerator working between 300 C
and 00 C?

Answer 1

Given :
T2=0 °C=273k

T1=30 °C= 273+30=303K

Formula to be used :

β=T2/T1-T1
=272/303-273
=272/30
=9.1

∴coefficient of performance (β) of a Carnot refrigerator is 9.1

Answer 2

Heya,

Answer to your question is:-

T2=0 °C=273k

T1=30 °C= 273+30=303K

=> β=T2/T1-T1
=272/303-273
=272/30
=9.1

HOPE THIS HELPS YOU:-))
