A balloon filled with air at 1.50 ATM and a temperature of 20.0 Celsius has a volume of 2.25 L. If the balloon is left in the warm sun, what will be the pressure of the air inside it when its temperature has risen to 25.0 Celsius and its volume has increased to 2.45 L?

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.
