A sheet of gold weighing 10.0 g and at a temperature of 18.0°C is placed flat on a sheet of iron weighing 20.0 g and at a temperature of 55.6°C. What is the final temperature of the combined metals? Assume that no heat is lost to the surroundings. The specific heats of the metals are given in Table 5.2.) 0.1 mm. After taking the measurements, convert all lengths to the specified units on the report sheet. Be sure to show all your work for the conversions. Next determine the volumes of test tubes by two different methods. In method one, use the cm ruler to measure inside diameters and lengths of two different test tubes to the

4) Calculate the speclfic heat of a metal if adding 100.0 g of the metal at 50.0'C IS added to 50.0g of water at 20 C results in a final temperature of 23.10'C. The cwater is 4.184 J/g C. Ibo, (23.10-50) IÙO 50 20) 5) A 2.50 g sample of zinc is heated, then placed in a calorimeter containing 65.0 g of water. Temperature of water mixing. Sheet bars weighing 100 grams were hydraulically pressed in a single-action die from the blended powders at 12.5 tons per square inch into compacts measuring approximately 6 by 1by 0.10 inch. Some of the important processing conditions related to sintering, heat treatment, and rolling are shown in table II.
