What happens if the kinetic energy of a gas is lowered?
O
O
A. The gas forms a solid.
B. The temperature increases.
O. c. The volume increases.
O
D. The pressure decreases.

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.
