How much kinetic energy (KE) does an object with a mass of 1.200 x 10' g traveling 1. in a straight line with a speed of 5.0 x 10' m s' possess? 3. A sample of zine weighing 425.0 grams initially at a temperature of 25.40 C required 1360.0 joules of heat energy to increase the temperature to 33.70 C. What is the molar heat capacity of the zine? 4. The specific heat capacity of copper metal is 0.38 J/g C. Assume a 75 g cube of copper at 25 C. What would the final temperature of the copper be (in C) if it absorbed 1.50 x 10 J of heat energy? 5. What is the resulting temperature in Kelvins when 35 g of water at 75 C is mixed with 15 g of water at 15 C? (Heat capacity for water = 4.184 Jig C) 6. When 72 g of a metal at 97.0 C is added to 100.0 g of water at 25.0 C the final temperature is found to be 29.1C. What is the heat capacity of the metal? (specific heat capacity of water - 4.184 J/g "C).
