Question

Combination of 0.38 kg of water at 22.64°C, 0.54 kg of aluminum at 29.16°C, and 0.14 kg of lead at 100°C is mixed in an insulated container and allowed to come to thermal equilibrium. Ignore any energy transfer to or from the container. Calculate the final temperature in °C of the mixture. C(Water) = 4186 J/kg K C(Aluminium) = 900 J/kg K C(Lead) = 128 J/kg K Note: Answer will be up to two decimal places.

Step 1

38 kg Specific heat capacity of water, C1 = 4186 J/kg K Initial temperature of water, T1 = 22.64°C = 22.64 + 273.15 K = 295.79 K Final temperature of the mixture, T Using the formula Q = m * C * ΔT, where Q is the heat energy absorbed, m is the mass, C is the Show more…
