MCQ – Particulat Nature of Matter

1. Matter is anything that occupies space and has mass.
2. The particle theory of matter states that matter is made up of a large number of tiny and discrete particles.
3. The kinetic energy of the particles in a matter increases if its temperature increases.
4. The particles in all kind of matter are identical.

1. Solid > Liquid > Gas
2. Solid < Liquid < Gas
3. Solid = Liquid = Gas
4. It depends on what kind of substance it is.

1. Particles move randomly and slowly and sometimes will collide against each other.
2. The volume of the object is not fixed.
3. Particles are not arranged in order. Most of the particles are still in contact with one another.
4. Difficult to be compressed.

1. The particles of gas move at high speed
2. The collision between the gas particles and the wall of the container is elastic.
3. The gas particles move randomly in all direction.
4. The gas particles are arranged in regular patterns.

1. Water molecules get nearer to each other.
2. Energy is absorbed from the surrounding.
3. Water molecules are not arranged orderly.
4. The mass increase.

1. Iodine
2. Dry ice (Solid carbon dioxide)
3. Naphthalene
4. Ammonium Chloride

Matter is made up of a large number of tiny and discrete particles.

1. Brownian Motion
2. The shape of a solid is fixed.
3. Diffusion of bromine vapour in gas.
4. The volume of a substance increase when it transforms from a liquid into gas.
