Answer:
anything that has mass and takes up space by having volume
solid , liquid and gas are the three states of matter .
solid- Solid matter is composed of tightly packed particles. ...
Liquid matter is made of more loosely packed particles. ...
Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume.
liquids are the matter that get adjusted to any shape of container they change their shape but they have the same volume.
liquids can flow but can't be compressed because the particles present in them are packed close together.
gases are freely Expandable and they do not have definite shape not definite volume

2. a.Ans: A substance that flows freely but is of constant volume, having a consistency like that of water or oil is called liquid.
b. Ans: Because the particles can move, liquids don't have a definite shape, and they can flow. Because the particles are still packed close together, liquids can't easily be compressed and keep the same volume.
3.a. Ans: The gaseous state is one of the four fundamental states of matter (along with the solid state, the liquid state, and plasma). The most common example of a gas is air (the air we breathe is a gas). ... It can also be considered as a mixture of many gases such as nitrogen, oxygen, and carbon dioxide.
