Question

I have given the answers but please show the work for all parts of the question.

(Measurement of Heat) A cubic brass shot with volume of 8 cm³ (side lengths are: 2 cm) is heated from 20 °C to 620 °C and then dropped into a 100g Aluminum container containing 400g of water. The temperature of the container and water are initially 10 °C. (assume no heat exchange with the surrounding air etc. and Density of brass is 8.73 g/cm³)

Part 1. How much Heat is needed to heat up the brass shot? Give your answer in Joules and Calories to the nearest whole unit

Answer: 16343 J

Answer: 3939 Calories

Part 2. If the emissivity is 0.73, what is the Heat Current of radiation of energy for the brass shot when it is pulled from the heating forge at temperature?  Give your answer to the 3 significant digits

Answer: 57.7 W

Part 3.What is the equilibrium temperature of the system once the shot is added to the container? Give your answer to 4 significant digits

Answer: 19.26 Degrees Celcius

Part 4. What is the Heat lost by the brass? Give your answer to the nearest whole Joule

Answer: 16363 J

Part 5. What is the Heat gained by each the water and aluminum? Give your answer to the nearest whole Joule

water = 852 J

aluminum = 15,510 J
