Question 1
1 / -0

The Kinetic Molecular Theory gives postulates that define matter and help to understand its properties. From the options provided below, select the one that is not a characteristic of matter.

A
Matter in any state is composed of small particles, which may be molecules, atoms, or ions.

B
Particles are arranged in such a way that there are no spaces between the particles.

C
Particles are in continuous random motion.

D
Molecules of a given substance attract each other.

Solution

Particles of matter have space between them, though the space is maximum between the particles of a gas and minimum between the particles of a solid substance.
Question 2
1 / -0

What is the reason that sugar crystals when added to water dissolve on stirring, but the same does not happen in case of a stone?

A
Stone particles have stronger forces of attraction between themselves than sugar particles.

B
Sugar particles have less space between themselves than stone particles.

C
Stone particles are bigger in size than sugar particles.

D
Stone particles possess more kinetic energy than sugar particles.

Solution

The constituent particles of stone have strong associations and do not dissolve in water.
Question 3
1 / -0

Which of the following has the highest kinetic energy?

A
Solid

B
Liquid

C
Gas

D
Plasma

Solution

Plasma comprises highly energised, ionised gas particles and the kinetic energy of this state of matter is the highest.
Question 4
1 / -0

Under which of the following conditions will the particles present in a crystal of copper sulphate take the least time for intermixing with the particles of water?

A
When water is hot

B
When water is cold

C
When water is taken at room temperature

D
When distilled water is used

Solution

The particles of copper sulphate mix with the water molecules due to the property of diffusion of the particles.

The rate of diffusion increases with increase in temperature, as the particles gain kinetic energy. Hence, the intermixing will be the fastest in hot water.
Question 5
1 / -0

What does the melting point of a solid indicate?

A
Randomness of its particles

B
Strength of forces of attraction between particles

C
Kinetic energy of particles

D
Intermolecular space between particles

Solution

Melting point of a solid is an indication of strength of the forces of attraction between its particles.
Stronger the intermolecular forces, higher the melting point.
Question 6
1 / -0

Early Indian and Greek philosophers classified matter

A
on the basis of their physical properties

B
on the basis of their chemical properties

C
as 'Panch Tatva'

D
as 'Parmanu'

Solution

Everything in this universe is made up of matter. The air we breathe, the food we eat, stones, clouds, stars, plants and animals, even a small drop of water or a particle of sand, everything is matter. Ancient Indian philosophers classified matter in the form of five basic elements - The Panch Tatva, i.e. air, earth, fire, sky and water. Ancient Greek philosophers also gave similar classification of matter. Modern day scientists evolved the types of matter based on their physical and chemical properties.

On the basis of physical properties, matter is classified as solids, liquids and gases and on the basis of chemical properties, matter is classified into elements or compounds.

Moreover, long back in around 500 BC, an Indian philosopher Maharishi Kanad postulated that if we go on dividing matter, we shall get smaller and smaller particles called Parmanu.
Question 7
1 / -0

Which of the following statements is true about evaporation?

A
It increases with increase in temperature.

B
It occurs at a fixed temperature.

C
It depends on the latent heat of fusion.

D
It decreases with increase in temperature.

Solution

Evaporation is the phenomenon of change of liquid into vapour at any temperature below its boiling point.

The rate of evaporation is directly proportional to the surrounding temperature.
Question 8
1 / -0

Ice floats on water because

A
solid state of any substance is less dense than its liquid state

B
solid state of any substance is more dense than liquid state

C
on solidification, the water molecules form H-bonds

D
on solidification, the substance acquires a definite volume

Solution

A special force of attraction that exists between the water molecules is called hydrogen bond because of which it, on cooling, form a honeycomb-like structure. The air trapped in air spaces makes ice less dense than water. Thus, it floats on water.
Question 9
1 / -0

Why does an inflated balloon burst with a sound when it is pricked with a needle?

A
Because of force exerted by the needle

B
Because of force exerted by gas present in the balloon

C
Because of decreasing kinetic energy of gas

D
Because of high temperature inside the balloon

Solution

On pricking, the balloon bursts and the gas within expands.

Gases produce a sound on expansion as the expansion work done by the gases is converted into sound energy.
