Thank you very much for replying! :smile: Please forgive me, as I understand only a speck of physics.
This makes sence:
What do you mean by this?
Is it a matter of using the distributive property in algebra?
q = 1 c (T-20) + 4 c (40-T) = 5 c T
q = 1cT -20c + 80c -4cT = 5cT
q =...
Homework Statement
What would be the final temp if you mixed 1 liter of 20°C water with 4 liters of 40°C water?
This question is very straightforward, and is, of course, assuming total conservation of temp.
Homework Equations
My book mentions q=mc∆t, but using that equation, I get...
