Which substance needed a greater increase in kinetic energy in order to change phase? The substance with medium attraction needed more energy transferred in in order to
change phase.

The substance with high attraction needed more energy transferred in in order to
change phase.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
