Initial Temp Homework: Copper in Water, Aluminum Cup

AI Thread Summary
The discussion revolves around a thermal equilibrium problem involving heated copper, an aluminum calorimeter cup, and water. The student needs to determine the initial temperature of the copper after mixing it with the cup and water, which all reach a final temperature of 28°C. The relevant equations for specific heat and heat transfer are provided, emphasizing the relationship between heat gained and lost. The total heat exchange equation, Qcalorimeter + Qsolution + QWater = 0, is noted as critical for solving the problem. The student expresses uncertainty about how to apply these concepts to find the solution.

Homework Statement


A student doing an experiment pours 0.150 kg of heated copper **** into a 0.375 kg aluminum calorimeter cup containing 0.200 kg of water. The cup and water are both initially at 25 C. The mixture (and the cup) comes to thermal equilibrium at 28 C. What was the initial temperature of the shot?


Homework Equations


The only equations in the chapter are specific heat:

Q=cm(delta)T or c=Q/m(delta)T

The Attempt at a Solution



No clue

DeltaT = Tf -Ti

Qcalorimeter + Qsolution + QWater = 0
 

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...
