Which state of matter has no definite volume or definite shape but expands to fill the available volume of a container?

Gases

Explanation: There are three states of matter:

1.Solid state : In this state, the molecules are arranged in regular and repeating pattern. They have fixed volume and fixed shape.

2. Liquid state : In this state, the molecules are present in random and irregular pattern.  They have fixed volume but acquire the shape of the container.

3. Gaseous state : In this state, the molecules are present in irregular pattern. They have neither fixed shape nor volume. They fill the entire volume available.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.
