Testing the mathjax engine
From \(Q = mC\Delta T\) you will get \(\Delta T = {Q\over mC}\), with \(C=4182 {J\over kg \Delta K}\) being the specific heat of water at 20ºC. With this you get \[\Delta T = {25000 J\over 2kg · 4182 {J\over kg \Delta K}} = 2.989 \Delta K\]
Then the final temperature will be: \(T_0+\Delta T = 20 ºC + 2.989 \Delta K =\) Inconsistent units. César  Information must flow.

$\frac{N_i}{D_i}=\frac{N_{i1}}{D_{i1}}+\frac{1}{F_i}=\frac{F_i\cdotN_{i1}+D_{i1}}{D_{i1}\cdotF_i}$

Kelvin degrees = Centigrade degrees + the absolute zero offset Offsets are canceled in the Delta, so that there would be no incoherence. The same Delta in Centigrade degrees would have the very same value. Fahrenheit degrees are another story, you know.
