Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of Īµ, where =ĪµĆ1.010ā24 j. in other words, each no2 group could have Īµ of rotational kinetic energy, or 2Īµ, or 3Īµ, and so forth ā but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32Īµ. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18Īµ. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5ļ°c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/gādegree c). calculate the calorimeter constant. (smĪ“t)warm water = -[(smĪ“t)cold water + (calorimeterĪ“tcold water)]
