Consider these electron transitions in a hydrogen atom: I. n = 2n=1
II. n = 3-n=1
III. n= 1 ->n= 4
Which of the electron transitions would release the most energy?
A)
B) II
C) III
D) I, II, and Ill release the same amount of
energy

Melting 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.

What is the standard unit of measure for acceleration?

In a heat of an engine, if 700 j enters the system, and the piston does 400 j of work what is the final internal (thermal) energy of the system if the initial energy is 1,500 j
