A calorimeter contains 125 grams of water at 18°C. A 700-gram copper cylinder at 100°C is placed into the calorimeter. What is the equilibrium temperature, assuming no loss of heat to the surroundings?
.5 M H2O4 17) A 100-gram sample of copper at 100.0°C is added to 50.0 grams of water at 26.5°C in a thermally insulated container. What will be the final temperature of the Cu-H20 mixture if the specific heat of Cu-0.384 J/goC? (assume the specific heat of water is 4.184 J/g C and the density of water is 1.00 g/mL) (10 pts) your answer
Calculate the final equilibrium temperature when 10.0 grams of steam initially at 100 degree C is mixed with 450 grams of liquid water and 110 grams of ice at 0 degree C in a calorimeter. That is, the liquid water AND the ice are initially at 0 degree C. Ignore any heat energy exchanges with the calorimeter and the surroundings. If you conclude that the final temperature of the system is 0 degree C, then what mass of ice remains,...
A 45.5 gram sample of a mineral is placed in boiling water until its temperature is 100 degrees C. It is then placed in 255 grams of H20 with a temperature of 22.5 degrees C. The final temperature of the system settles at 32.4 degrees C. What is the specific heat of the mineral?
If a 40 g block of copper metal at 100oC is added to 100 g of water at 25oC, calculate the final temperature of the system. Cs water = 4.18 J/g oC. Cs copper= 0.385J/g oC.
Calculate the final temperature of the system: A 50.0 gram sample of water initially at 100 °C and a 100 gram sample initially at 20.72 °C are mixed. The specific heat of water is 4.184 J/gC). Record your answer in scientific notation using 3 significant figures.
A hot lump of 35.6 g of copper at an initial temperature of 86.3 C is placed in 50.0 mL initially at 25.0 °C and allowed to reach thermal equilibrium. What is the final temperature of the copper and water, given that the specific heat of copper is 0.385 J/(gxC). Assume no heat is lost to surroundings.
A piston–cylinder assembly contains ammonia, initially at a temperature of -20°C and a quality of 40%. The ammonia is slowly heated to a final state where the pressure is 6 bar and the temperature is 100°C. While the ammonia is heated, its pressure varies linearly with specific volume. For the ammonia, determine the work and heat transfer, each in kJ/kg.
