A sample of gas whose volume at 25 C is 0.170 L, is heated at a constant pressure until its volume becomes 184 ml. What is the final temperature in Kelvin? Answer
with no decimal places

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.
