Chemistry ch-3 Matter

An object may or may not have a definite shape. It may or may not be able to flow from one place to another. Based on these properties, matter exists in different forms. Which of the following are the three forms of matter commonly found on Earth?

• Solid, Plasma, Gas

• Solid, Liquid, Gas

• Liquid, Gas, Bose-Einstein Condensate

• Plasma, Bose-Einstein Condensate, Solid

The state of matter that has a definite shape, a definite volume, and does not flow from one place to another on its own is called:

• Liquid

• Gas

• Solid

• Plasma

According to the sources, which of the following is a property of a liquid?

• It has a definite shape.

• It cannot flow.

• It has only one free surface.

• It is very hard, like diamond.

A gas is defined as the state of matter that has:

• A definite shape and definite volume.

• No definite shape, but a definite volume.

• No definite shape, no definite volume, and definite direction of flow.

• No definite shape, no definite volume, and can flow in all possible directions.

Which of the following is an example of a gas given in the sources?

• Milk

• Wood

• Oxygen

• Mercury

The theory stating that matter is made up of very small particles (molecules or atoms) and the arrangement of these particles determines its state is known as:

• Atomic Theory

• Particulate Nature of Matter

• Kinetic Theory of Gases

• Brownian Motion Theory

In which state of matter are the particles most loosely packed and possess the maximum inter-particle space?

• Solid

• Liquid

• Gas

• Plasma

What is the force of attraction or repulsion that exists between particles and is called 'cohesive force'?

• Inter-particle space

• Brownian motion

• Inter-particle force

• Diffusion

The random movement of particles in a fluid, such as the movement of dust particles in a room or carbon particles in smoke, is called:

• Diffusion

• Inter-particle motion

• Brownian motion

• Cohesive force

The intermixing of substances by the natural movement of their particles is called:

• Melting

• Freezing

• Diffusion

• Condensation
