⁠

Fill in the blanks

Anything that has mass and occupies space is called _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Matter

According to scientists, matter was created in an explosion in the universe called the _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Big Bang

Matter that grows, moves and reproduces on its own is called _ _ _ _ _ _ _ _ _ _ _ _ _ _ matter.

Living

Matter that is found in nature is called _ _ _ _ _ _ _ _ _ _ _ _ _ _ matter.

Natural

The quantity (amount) of matter contained in a thing (object) is called its _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Mass

The space occupied by matter is called its _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Volume

The smallest particle of matter that exhibits all the properties of matter and has an independent existence is called a _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Molecule

Atoms and molecules are very small; they cannot be seen even by an _ _ _ _ _ _ _ _ _ _ _ _ _ _ microscope.

Ordinary

The continuous zigzag motion of particles is known as the _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Brownian motion

The force of attraction between the same kind of particles is called _ _ _ _ _ _ _ _ _ _ _ _ _ _ force.

Cohesive

The force of attraction between different kinds of particles is called _ _ _ _ _ _ _ _ _ _ _ _ _ _ force.

Adhesive

The space between the particles (molecules) of matter is called _ _ _ _ _ _ _ _ _ _ _ _ _ _ space.

Intermolecular

Matter exists in three states: solid, _ _ _ _ _ _ _ _ _ _ _ _ _ _ and gas.

Liquid

Besides solids, liquids and gases, other states of matter include plasma, Bose-Einstein Condensate, and _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Fermionic Condensate

In solids, the intermolecular space is _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Negligible (or very small)

Liquids have a definite _ _ _ _ _ _ _ _ _ _ _ _ _ _ but do not have a definite shape.

Volume

Gases are _ _ _ _ _ _ _ _ _ _ _ _ _ _ compressible due to large intermolecular space.

Highly

Substances that can flow easily are called _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Fluids

The process during which a solid changes into its liquid state at a fixed temperature on heating is called _ _ _ _ _ _ _ _ _ _ _ _ _ _ or fusion.

Melting

The fixed temperature at which a liquid changes into its vapour state is called its _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Boiling point

The temperature remains constant as long as _ _ _ _ _ _ _ _ _ _ _ _ _ _ continues during a state change.

Melting (or Boiling)

The process during which a liquid changes into its vapour, at temperature below the boiling point is called _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Evaporation

The process during which a gas changes into its liquid state at a fixed temperature on cooling is called _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Condensation

The process during which a liquid changes into its solid state at a fixed temperature (on cooling) is called _ _ _ _ _ _ _ _ _ _ _ _ _ _ or solidification.

Freezing

The process by which vapour changes directly into solid on cooling is called _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Deposition

_ _ _ _ _ _ _ _ _ _ _ _ _ _ balls are used to protect woollen and silk clothes from moths.

Naphthalene

Dry ice is an example of a _ _ _ _ _ _ _ _ _ _ _ _ _ _ substance.

Sublimable

All the three states of matter expand on heating and _ _ _ _ _ _ _ _ _ _ _ _ _ _ on cooling.

Contract

When we burn a paper, it changes into _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Ash

LPG (Liquefied Petroleum Gas) is present in _ _ _ _ _ _ _ _ _ _ _ _ _ _ form in the cylinder due to high pressure.

Liquid

Solids generally exert pressure only at their _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Base

Liquids exert pressure in _ _ _ _ _ _ _ _ _ _ _ _ _ _ directions.

All

Gases exert pressure on the _ _ _ _ _ _ _ _ _ _ _ _ _ _ of the container.
