A refrigerator has coefficient of performance 8 if the temperature in freezer is -23 degrees,what is the temperature at which it rejects heat?

↳Redirected from "Suppose that I don't have a formula for #g(x)# but I know that #g(1) = 3# and #g'(x) = sqrt(x^2+15)# for all x. How do I use a linear approximation to estimate #g(0.9)# and #g(1.1)#?"

Coefficient of performance (#beta#) for a refrigerator is given as #beta = T_2/(T_1-T_2) # (where, #T_1# is the temperature of heat source i.e at which it will reject heat and #T_2# is the temperature of heat sink i.e temperature in freezer)

Given, #beta = 8,T_2 = (273-23) K =250 K#

So, putting the values, #T_1 = 281.25 K#
