oohhh i totally missed that i got it now. Thanks for all the help:biggrin: i might be posting another one that's giving me trouble, I'm gona see if i can figure it out.

So \DeltaQsteam +\DeltaQcola=0 Heat lost by one system = heat gaind by the other DQ steam = DQ cola In my book the formula latent heat is Q=ML there is no change in temp 500 * 1 * (20-90) = M steam 540 Where would I put change in temp of the steam from 100-90?? The...

well i the question stated heating .50 kg of cola (mostly water), by adding steam. How musch steam should be bubbled in so that the final temp. is 90 deg C. isnt the steam just being used as the heat source? so your saying that i have to take into account the steam that turns back into water...

I was doing it differently I was using the conservation of energy SDQ=0 So I was doing DQcola + DQsteam =0 (cola in prob. said to be mostly water so I used water) I did M cola * c cola * DT + M steam * L vap. = 0 500 * 1 * (20-90) + M steam * 540 =0...

20 deg C was not listed in the prob. so i used it i remember our teacher saying if its not listed in the prob. to use 20 deg C. so my eqn would look like this? 500 * 1 (20-90) + M steam * .480 (100-90) M steam = 7.3 kg i don't have the answer to the prob. to check to see if its...

Homework Statement heating .50kg of diet cola mostly water, by adding steam. How much steam should be bubbled in so final temp. is 90 deg C Homework Equations what i tired so far downt know if it the right way to go abotu the problem is specific heat capacity Q=mc detlaT E tot of the...

i figured it out this moarning

Homework Statement This was a lab we did in class 2 day we took the measured the weight of a chicken in the air and in water. Than found the masses and mass of h20 displaced and the volume displaced Mass chicken in air = 1.489 kg Mass chicken in h20 = .112 kg Mass h20 displaced =...
