O ile stopni ogrzano 5l wody grzałką o mocy 1 KW w czasie 5min

[latex]m_{wody} approx 5[Kg], P = 1KW, t = 5min = 300s \ W = E_{cp} \ W = Pt \ E_{cp} = m*C_p *Delta T \ Pt = mC_p Delta T \ Delta T = frac{Pt}{mC_p} \ Delta T = frac{1000W*300s}{5Kg*4200frac{J}{Kg* ^circ}}\ Delta T approx 14.29 ^circ [/latex]
