25. 30.0 g of 271.4°C liquid bismuth (Bi) is added to 80.0g of 25.00°C water in a perfectly insulated container. Af...
1) 150 g of a liquid at 45°C is filled in an insulated metal container at 35°C whose mass is 110 g. The system eventually reaches an equilibrium. Find: (a) the final equilibrium temperature, and (b) estimate total change in entropy of the system (i.e. metal container plus liquid). Specific heat of liquid is 4186 J/kg.Cº and specific heat of metal is 900 J/kg.C. 2) A Carnot engine working between a hot and cool reservoir, extracts 800 J from a...
1. Liquid nitrogen at −196° C (nitrogen’s boiling point) is placed in a container with 3 kg of water at 25° C. (a) Suppose you add just enough liquid nitrogen such that all the water just freezes (i.e., the final state of the water is ice at 0° C). Draw a complete energy interaction diagram for this scenario, including a conservation of energy equation. (b) How much liquid nitrogen should you put in the container such that all the water...
9. Four ice cubes exactly at-50 °C with a total mass of 53.5 g are combined with 1 15 g of water at 75 °C in an insulated container. If no heat is lost to the surroundings, what is the final temperature of the mixture? The heat capacity of ice is 2.03 JIg C and that of water is 4.18 JIg C. The heat of fusion of water is +6.01 kJ/mol. (1.5 pts) 9. Four ice cubes exactly at-50 °C...
