Impossible tHERMODYNAMICS Problem

AI Thread Summary
The problem involves calculating the work done and the increase in internal energy when nine grams of water vaporizes at one atmosphere. The latent heat of vaporization is given as 2.26 × 10^6 J/kg. The volume change during the process is from 0.5 cm³ to 2165 cm³. Users are struggling with unit conversions and calculations, particularly in applying the formula for work, W = change in volume * pressure. Detailed calculations and unit handling are requested for clarity.

Homework Statement


Given: latent heat of vaporization of water = 2.26 × 106 J/kg .
Nine gram of water changes from liquid to vapor at a pressure of one atmosphere. In the process, the volume changes from 0.5 cm3 to 2165 cm3.
Find the work done. Answer in units of J.

Find the increase in internal energy of the water.
Answer in units of J


Homework Equations



Latent Heat=2.26x10^6(kg)
this doesn't work

W=change in volume * pressure

The Attempt at a Solution


i have plugged in the values for the first section and they do not work. Changing to pascals/kg aren't right.

Thread 'Errors and significant figures'

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'

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...
