Unformatted text preview: Explain and support your answer with calculations. (4pts) c) Calculate the final temperature, T f , exactly. (4pts) 2) (8 pts) 2.5 kg of liquid mercury at 274 K is added to 3.3 kg of water at 300 K. The new mixture is allowed to come to thermal equilibrium in a sealed container. Substance Specific Heat (kJ/kg*K ) Mass (kg) Initial Temperature (K ) Mercury .140 2.5 274 Water 4.18 3.3 300 There are no phase changes involved and you may assume no heat enters or leaves the container. a) Draw a complete energy interaction diagram for this problem. b) Clearly write down the expression, using conservation of energy, which will allow you to find the final equilibrium temperature of the mixture. YOU DO NOT HAVE TO SOLVE FOR THE FINAL TEMPERATURE VALUE !!!!!!!!!!!!!!...
