what measurements of water do I add?
« on: September 14, 2014, 10:29:03 PM »
If you have two separate things of water...one ice cold water ( 0 degrees celsius) and the other room tenperature water. How do you solve how much  water you add from both to equal 12.8 degrees Celsius??

(Specific heat of water x Volume of water x Change in Temperature of water)1 = (Specific heat of water x Volume of water x Change in Temperature of water)2

You want to find how much water to add as a ratio. Need more help let me know  ;D

Specific heat of water = 4.186 joule/gram °C This really doesn't matter, look at the equation!

Would this equation work:

q=m • c • ▲T

Yes, that's the equation you need.

q=200.0 mL • 1.000 cal/g. ºC • 23.7 ºC

Is that correct?  Would I do two equations that way with different temperatures?

It is definitely correct for SOME problem. Whether it is OK for the one you are trying to solve, I have no idea.
