If matter has a definite volume but no definite shape, in what state is it?

Liquid state

Explanation:

There are three states of matter named as solid , liquid and gas.

Solids have fixed shape and fixed volume as the molecules are strongly bonded to each other.

Liquids have fixed volume but no fixed shape as the molecules are weakly bonded to each other.

Gases have neither fixed shaped nor fixed volume as the molecules are very weakly bonded to each other.

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.
