Since a large number of bonds must be broken to increase the molecular movement (more movement means higher temperature) it takes a lot of energy to break bonds which increases movement and through movement temperature. Therefore water has a high heat capacity because lots of energy is required to raise the temperature of water by 1 C 4 4. 10pts 5 5a. 3 pts (a,b) 4 pts for c, 10 pts total 5b. 2 pts first correct 1 pts second correct 5c. 6 6.
