Which reaction is an example of natural transmutation?
(1) 239/94 Pu ->235/92 U + 4/2 He
(2) 27/13 Al + 2/4 He ->30/15 P + 1/0 n
(3) 238/92 U + 1/0 n → 239/94 Pu +2 0/-1e
(4) 239/94 Pu 1/0 n → 147/56 Ba + 147 56Sr + 3 1/0 N

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.
