I have done some exercises in general chemistry book. As I studied, the specific heat capacity is different for different substances. But in exercises, they assume that the heat capacity of solution os 4,18kJ (equal to that of water). The solution includes...

Right. This should be very straightforward, but I'm not sure whether I'm over-thinking this, or if I'm just being plain stupid, and I'm getting myself into a bit of a tizz about not quite getting this concept. Help would...

You should probably assume that there is perfect mixing and no loss of heat C (the boiling point of water).
Form as the first one: q3 = mhg * cphg * (Tf-T2)
(where T2 is 235 °C and cphg is the specific heat where to start.

Is there a catch all formula for calculating how long it will take to go from one temp to the other, if I manually time certain values?
Ex: If I know that it takes 1 hour to get the house from 15 to 20 when it's -20 outside, am I also able to calculate...

I've calculated since they're hidden.
Any large trace or poured plane quickly sinks heat away from the solder point.
