Question

A 12.99 gram sample of copper that is at 7.9 ^oC is added to 20.00 g of hot water that is initially at 93.2 ^oC.

From the First Law of Thermodynamics, what is the equation relating the sum of the heats of the two components?

Algebraically substitute in symbols for the Specific Heat Capacities for the copper and water (Cs_Cu, and Cs._H2O), the symbols for masses (m_Cu and m_H2O) and the symbols for the temperature change (T_f, T_i,Cu, and T_i,water).

Solve the algebraic problem in (b) for T_f, the final temperature of water.
