Calculations Lab: Heats of Fusion and Vaporization

AI Thread Summary
The discussion focuses on a homework question regarding the calculation of heats of fusion and vaporization. The user converted grams to kilograms and followed the correct order of operations while solving the problem. They arrived at a heat transfer value of 1827.88 cal/g but questioned the unit's correctness. Feedback indicates that the calculated value is slightly low and suggests verifying whether the units should be kcal/kg or cal/g. The final result should consistently use either Joules or calories as the unit of measurement.

Homework Statement



Hi, I am answering Question #3, and using the formula and variables above scratch area as reference on how to answer the question.

Could someone please have a look and see if the problem I worked out came out correct.

Homework Equations


The Attempt at a Solution


First I converted g = kg
I used the given variables, then I work out the problem, I made sure to do the paranthesis first before multiplying the variables in,
then converted back to kg and finally came with the answer

1827.88 cal/g heat transfer, did i use the correct unit? joules?
Any input would happily appreciated

You're answer is in the right ballpark (but a bit low). You've specified your heats of fusion and vaporization with units of cal/kg, whereas the number magnitudes look like they're more suited to being kcal/kg or cal/g. Check them.

The final result should have units pertaining to heat only: either Joules or calories.
 
ok thanks,
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
