Heat and Mass: Raising Ice and Water Temperatures

AI Thread Summary
Raising the temperature of 5 grams of ice by 6 degrees Celsius requires more thermal energy than raising the same amount of water by the same temperature increase. This is due to ice's lower specific heat capacity, which means it takes more energy to change its state from solid to liquid before its temperature can increase. The confusion arises because while water can increase in temperature directly, ice must first absorb energy to melt. Therefore, the energy required to raise the temperature of ice includes both the energy needed to melt it and the energy to increase its temperature. The conclusion is that ice indeed requires more energy for this temperature change.

Homework Statement



Given that ice has a specific heat that is half of that of water, does it take more thermal energy to raise the temperature of 5 grams of water or 5 grams of ice by 6 degrees Celsius?

Homework Equations



Q=mc delta t


The Attempt at a Solution



So I think it takes more energy to raise the temperature of water. Am I right? The answer given is ice, could that just be a mistake?

If you assume the temperature of the ice is zero degree, the ice takes more energy to melt and then rise the temperature. Where as the water directly rises the temperature.
 

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'

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...
