Final Temp of Water in Calorimeter After Heating Silver Ring

AI Thread Summary
The discussion revolves around calculating the final temperature of a silver ring and water system, considering energy transfer to the surroundings. The silver ring, weighing 25.5 grams and initially at 84 degrees Celsius, is placed in a calorimeter with 0.05 kg of water at 24 degrees Celsius. The calorimeter loses 0.140 kJ of energy to the environment before reaching thermal equilibrium. The participants initially express confusion about applying conservation of energy principles but ultimately resolve the problem independently. The focus remains on understanding the heat transfer without phase changes involved.

A 25.5 gram silver ring ( c=234 J/kg * c) is heated to a temperature of 84 degrees C and then placed in a calorimeter containing 0.05 kg of water at 24 degrees C. The calorimeter is not perfectly insulated and .140 kJ of energy is transferred to the surrounding before a final temperature is reached. What is the final temperature?

Ok, I was thinking that there is no phase change so I am not sure is it just conservation of energy, and if so, how do I start?

Nevermind, I was able to figure it out.
 
I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
