heat flows into the system heat flows into the surrounding heat flows into both the surrounding and system no heat is involved none of the above

2. What is the work done for the change in volume of a gas of 17L at a constant pressure of 12 atm?
100 J 204 J -204 J 347 J -347 J

3. What is pyrolytic cracking?
process in which larger kerosene molecules are broken down into smaller molecules of hydrocarbon a procedure in which a more a practical source of energy is produced the use of pyrotechnics to mine coal a process of coal conversion none of the above

4. Heat capacity (C) is:
heat absorbed / increase in temperature heat absorbed / mass of substance increase in temperature / heat absorbed mass of substance / heat absorbed none of the above

5. 300. J of energy was released by solution A in a calorimeter. If the mass of solution A was 50.g and the T was 30.C, what is its specific heat capacity.
