    Lost Water
AI Thread Summary
When water is heated, it expands, leading to a decrease in density, which is why 0.34 g of water is lost from the container. As the temperature increases from 20 degrees C to 60 degrees C, the volume of water increases, causing some of it to overflow. The density of water at 60 degrees C is 0.98324 g/mL, confirming that warmer water is less dense than cooler water. This phenomenon explains the loss of water during heating. Understanding these changes in density and volume is crucial for grasping the behavior of liquids under temperature variations.

Homework Statement


It is observed that 55.50 mL of water at 20 degrees C completely fills a container to the brim. When the container and the water are heated to 60 degrees C, 0.34 g of water is lost. Density of water at 60 is 0.98324 g/mL.

I don't need help with solving it. I just need help understanding: why is water lost?

Thanks very much.

  • What happens to the density of the water when you heat it?
  • What happens to the volume?

Oh...it expands because density decreases.

Thanks for your help, really appreciated.
 

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...
