Suppose you mix 100.0 g of water at 24.8 oC with 75.0 g of water at 78.8 oC. What will be the final temperature of the mixed wat
klio [65]

Answer:

47.94^{\circ}\text{C}

Explanation:

m_1 = Initial mass of water = 100 g

c = Specific heat of water

\Delta T_1 = Temperature difference of the initial mass of water = (24.8-x)^{\circ}\text{C}

m_2 = Amount of water that is mixed = 75 g

\Delta T_2 = Temperature difference of the mixed mass of water = (78.8-x)^{\circ}\text{C}

x = Equilibrium temperature

The heat balance of the system is

m_1c\Delta T_1=m_2c\Delta T_2\\\Rightarrow 100(24.8-x)=75(x-78.8)\\\Rightarrow 2480-100x=75x-5910\\\Rightarrow -175x=-8390\\\Rightarrow x=\dfrac{8390}{175}\\\Rightarrow x=47.94^{\circ}\text{C}

The final temperature of the mixed water is 47.94^{\circ}\text{C}.
