13 12. What is specific heat? heat energy required to raise 1 kg by 10 degrees Kelvin  heat energy required to raise 1 kg by 1 degree Celsius heat energy required to raise 1 g by 1 degree Kelvin 

14 13. The heat energy required to raise 150. 0 ml of water from 2513. The heat energy required to raise ml of water from 25.0 oC to 80.0 oC is 3 450 J J  40 950 J  J

15 14. It takes 4500 J to raise the temp. of 0. 0100 kg of iron by 1. 0 K14. It takes 4500 J to raise the temp. of kg of iron by 1.0 K. What is its specific heat capacity? 450 J g-1 K-1   900 J g-1 K-1  45 J g-1 K-1  90 J g-1 K-1

16 15. Which of the following reactions is endothermic?Ice melting   Water freezing  Steam condensing  Gas burning

17 16. If ∆H is negative, then the reaction is...exothermic   endothermic  isothermic  at equilibrium

18 17. What is occurring during segment DE in this graph?Water is getting hotter Water is freezing Water is getting colder Water is boiling 

19 18. If 5852J of heat is added to a 40. 5 g sample of water at 30018. If 5852J of heat is added to a 40.5 g sample of water at K, what will its final temperature be? 340 K  325 K  330 K  335 K 

20 19. The specific heat capacity of water is unusually high. As a result…water is usually warmer than its surroundings ice is more dense than liquid water it is easy to raise the temperature of water it is difficult to raise the temperature of  water 

21 20. In calorimetry, the heat released by an exothermic reaction is absorbed by thereactants  surrounding water    atmosphere  thermometer

22 21. Water molecules are attracted to other water molecules21. Water molecules are attracted to other water molecules. This property is called _____ cohesion   adhesion  universal solvent  high specific heat

23 22. Is condensation endothermic or exothermic?Both neither
