HELP NO LINKS I MEAN IT Question 7(Multiple Choice Worth 2 points) (01.05 LC)

Because a gas has no definite volume or shape, in what way does it take up space?

By taking the volume of a solid
By taking the volume of a liquid
By taking the shape of its container
By taking the volume of its container

By taking the shape of its container

Explanation:

Gases are very floaty particles. They fill up the shape of their container because volume is determined by density and mass. Gases spread out to fill a container.

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.
