At 120° C a gas exerts a pressure of 212 kPa when its volume is 0.495 liters. If the temperature is raised to 240° C, at what volume will the pressure be 183 kPa?
*PLEASE SHOW WORK*

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.
