Osukuuni Practice Questions CHEM 1211 Thermochemistry 1. Classify the following processes as exothermic or endothermic: (a) freezing of water (b) melting of ice (c) boiling of water (d) heating with a furnace 2. Is the specific heat of a substance intensive or extensive property? Explain 3. Calculate q when 0.20 g of ice is cooled from 10 o C to -75 o C (C ice = 2.087 J/g.K). 4. A 325-g aluminum engine part at an initial temperature of 3.00 o C absorbs 85.0 kJ of heat. What is the final temperature of the part (C Al = 0.900 J/g.K)? ( 29 ( 29 C 3.00 T x g) (325 x J/g.K 0.900 kJ 1 J 1000 x kJ 85 o 2 - = 5. One piece of copper jewelry at 120 o C has exactly twice the mass of another piece, which is at 52 o C. Find the final temperature inside the calorimeter if both pieces are placed in the calorimeter. (Assume calorimeter has negligible heat capacity; C copper = 0.387 J/g.K) 6. An unknown volume of water at 18.2 o C is added to 24.4 mL of water at 35.0 o C. If the final temperature is 23.5
