what is the final temperature of a mixture of 135 g of of water at 21c?

Question

In a 45.0g brass calorimeter and 200g of silver at 1000.0 c

( sp.heat of brass =0.0917 cal/g c )
( sp.heat of silver = 0.0562 cal/g c)

Answer 1

Choose a reference temperature, calculate how much thermal energy it takes to heat up each element to it's given temperature. The divide that by the sum of each materials mass times its specific heat. That will give you the thermal rise above the chosen reference temperature.

You gotta learn how to do these if you're gonna make it through Physics ☺
