Temperature is the measure of the average 1. energy of the particles of an object. If more mass of the same type, and at the same
temperature, is added to an object, the object's temperature would 2.
The object's thermal energy would 3.
1. kinetic 2. stay the same 3. increase
O 1. kinetic 2. decrease 3. Increase
1. potential 2. stay the same 3. Increase
O 1. thermal 2. decrease 3. Increase

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.

the answer is 75.0%.
