A 83.0 g piece of metal with specific heat 0.622 Jg∘C and at 107∘C is placed in 300. g of water at 26.0∘C. What will be the final temperature of the water? Use 4.184Jg∘C for the specific heat of water.
If 400 J of heat were added to 100 g copper (specific heat = 0.385 J/g°C) and 400 J were added to 100 g of gold (specific heat = 0.129 J/g°C), which metal, copper or gold, would have the lower final temperature?
37) A student attempts to determine the specific heat of a metal by conducting a calorimetry experiment. The student heats 250 g of the unknown metal to a temperature of 38 C. They then place the metal into a calorimeter which contains 100 g of water at 21°C. The maximum temperature of the water rises to 27°C. a) What is the heat gained by the water in the calorimeter? Specific heat of water is 4.18 J/g'C. (5 points) b) What...
Question 4 4 pts A piece of metal with a specific heat of 1.29 J/gºC is heated to 126.6°C and then placed in 133.868 g of water which is at a temperature of 10.9 °C. After a minute, the temperature of the water has stopped changing and is now 45.6°C. Assuming that there are no heat losses to the container or surroundings, what is the mass of the piece of metal in grams? Assume that water has a specific heat...
