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 29.1°C. What is the heat capacity of the metal? (specific heat capacity of water - 4.184 J/g "C). 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.
