A gas has a volume of 50mL at a pressure of 2 atm. Increase the volume to 200mL, and the temperature remains constant. What is the new pressure?

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we are finding the new pressure we have

We have

We have the final answer as

Hope this helps you

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.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
