Thermal Equilibirum Calorimeter

AI Thread Summary
A copper calorimeter containing water and ice is in thermal equilibrium, and the problem involves adding lead at a high temperature to determine the final temperature. The relevant heat transfer formula is Q_1 + Q_2 + Q_3 = 0, where Q represents the heat exchanged. The initial temperature of the system is identified as the equilibrium temperature of ice and water, which is 0 degrees Celsius. Participants discuss the importance of starting with the correct initial temperature for accurate calculations. The conversation emphasizes proper forum etiquette for posting questions.

Question

A copper calorimeter can with mass 0.100 kg contains 0.160 kg of water and 0.018 kg of ice in thermal equilibrium at atmospheric pressure.

If 0.750 kg of lead at a temperature of 255 degrees C is dropped into the calorimeter can, what is the final temperature? Assume that no heat is lost to the surroundings.

Related Formula

Q_1 + Q_2 + Q_3 = 0

Q = mc\Delta T

\Delta T = T_{initial} - T_{final}

The initial temperature of the Ice/Water/Container, so I am not quite sure what the best way to start this question is.

Any suggestions?

As for your question, I offer you a hint: what is the temperature at which ice and water exists at thermal equilibrium?
 
Sorry, I htought there was something different:blushing: Feel free to move to 'Homework and Coursework: Introductory Physics' Category.

Would this be at the Triple point, which I is 0.0098 degrees Celcius, 273.1598 Kelvin. This must be the intial Temperature?

Correct! :approve:
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
