and the attatchment below is some of the examples i need help with.

Answer 1

im not asking for answers, just a how too

Answer 2

yes, i know this is not...physics i guess? but NOBODY IS ANYWHERE BUT MATH

Answer 5

clicking on the link won't work and byt the way, the website didn't help me much:(

Answer 6

From the attachment, it appears that you have 2 of the 4 values. It looks like you're supposed to fill in the last column (Q). The C in the formula is specific heat capacity. That could be looked up, but I don't know who's measured C for a blueberry Poptart.

Answer 7

The first half-page of this document gives a good description of the formula: http://physics.unl.edu/~lnicholl/lectures/notes/lec32-notes.pdf

Answer 8

C will be an issue. But M is the mass of the object (erroneously listed as Weight in the attachment), and delta T is the change in temperature. Units are important here. delta T will be the same in Celsius or Kelvin, mass is given in grams, and they want the answers in calories. So, you have to find values for C in those units, or convert the values you find to those units.

Answer 9

we are working on that in my chemistry class right now. thermochemistry. fun.
