If 7.84 × 107 j of energy is released from a fusion reaction, what amount of mass in kilograms would be lost? recall that c = 3 × 108 m/s.

7.06 × 1024

8.71 × 10-4

8.71 × 10-7

8.71 × 10–10

Temperature and kinetic energy are proportional. a) adirectly b) directly c) indirectly

Acontrol during an experiment. might change remains constant does not exist does change

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 23.5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/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
