A3.50 g sample of rice is burned in a bomb calorimeter containing 1680 g of water. the temperature of the water increases from 22.75°c to 27.84°c. how much heat, in joules, did the rice sample release when it burned? (c water = 4.184 j/g°c)1.88 x 10 5 j2.39 x 10 5 j5.08 x 10 4 j3.58 x 10 4 j4.22 x 10 2 j

Neils bohr believed that electrons orbited the nucleus in different energy levels, based on strong support from

Freezing and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
