1. The temperature difference between the inside and the outside of a home is 57.0°F Express this temp. in °C & K?

(a) By F-32 = 9C/5 =>57-32 = 9C/5 =>C = (25 x 5)/9 =>C = 13.89* (b) by T = 273+*C =>T = 273+13.89 =>T = 286.89*K

2. surface of an irregularly shaped conductor varies from 80.0 kN/C to 24.0 k, why can't it be calculated?

That is more likely because the units are not related to each other.. kN/C is the rate while k is the quantity of something. Good luck!
