Answer to Question #147817 in Physics for Abel Hannah

Question #147817

Calculate the final specific heat capacity (SHC) of the mixture of 30g Nacl (c=867 j/kgk) and of 30g Nacl(c=867j/kgk) and 5g of kcl (c=682 j/kgk).

Expert's answer

"c_{mix}=c_1\\frac{m_1}{m}+c_2\\frac{m_2}{m}=867\\cdot\\frac{0.03}{0.035}+682\\cdot\\frac{0.005}{0.035}=841(J\/kg\\cdot K)"
