Has anyone figured out Question 10?

Delta(W/Q) = __________________

Delta(W/Q) = sqrt((DeltaW/W)^2+(DeltaQ/Q)^2)*___

So what am I missing? Is it multiplied by something?

For above you have to multiply your error by W/Q since they are asking for the absolute error. Your equation is right just multiply that by W/Q
aS asked for above I also need some help on finding Delta Q(correct) and Delta Q(neglecting mass)

I tried that as well, Maple TA is marking it incorrect. At the end of my equation I add *(W/Q)

Value of DeltaQ (correct) = sqrt((Deltam/m of water)^2+(DeltadeltaT/DeltaT)^2)*Q of water

Value of DeltaQ (neglect mass error) = sqrt((DeltadeltaT/DeltaT)^2)*Q of water

what are the units for specific heat?
i think its joules/ gram degrees c but im not sure how to enter it into maple ta for question 1
thanks

The unit for specific heat should be cal/g/C or cal*g^-1*C^-1

I tried Question 10 again this morning and got it correct. I must have misspelled something or forgot something. Thanks!

Lab 10 Execution Empty Question7 second part

Post  guest23 on Tue Dec 09, 2008 6:35 pm

for the Value of deltaQ(correct) i used sqrt((Deltam/m)^2+(DeltadeltaT/deltaT)^2)*Q
for deltadeltaT i used sqrt((DeltaT_i)^2+(DeltaT_f)^2) and for delta T i used Tf-Ti and for Q i added all the Q's

My answer is still coming up wrong. for m do i have to add all the masses together and use .2 for deltam?

What am i doing wrong?

For Question 7 all it is asking for is the Q for each component. How do you find Q? [Hint: It's on the Preparation Lab 10 sheet. It's Question 2 and labeled as (2). It also tells you what each variable is supposed to represent].

Lab 10 Execution Empty Question 7

Post  J on Wed Dec 10, 2008 12:48 am

Yea, Q is easy, what about the bottom part of question 7, regarding Delta Q correct, and neglected Mass Delta Q. I know the equation, which i got right on the next question. What I want to know is what to use for the M, Delta M

Is Delta T= 0.5

and T= (Tf-Ti)?

Thanks for any help

I believe DeltaT is another number you had to calculate using 0.5oC. I do think that is the correct value for T. I have lab on Wednesdays so I haven't done calculations yet.

Try them in MapleTA and see if they come up correct, if it doesn't try other values in the calculations.
