Weekly Quiz Competition

Question 1
1 / -0

The interparticle attractive force ......... with increasing distance between particles.

A
Increases

B
Decreases

C
Increases moderately

D
None

Solution

As the particles move apart, their inter particle attractive force decreases with increasing distance.
Question 2
1 / -0

Matter is made up of:

A
Protons only

B
Electrons only

C
Neutrons only

D
All of these

Solution

Matter is made up of tiny particles called atom. Atoms has proton, electron and neutron in it. So, all of these are correct.
Question 3
1 / -0

Evaporation is a property of ______________.

A
solid

B
liquid

C
gas

D
all of the above

Solution

Evaporation is the process by which water is converted from its liquid form to its vapor form and thus it is a property of liquid.
Question 4
1 / -0

What can $$y$$ be in given Venn diagram?

A
Oxygen

B
Shampoo

C
Plasticide

D
Wax

Solution

Oxygen, being a gas, does not have definite volume nor definite shape. Hence, $$y$$ must be a gas i.e., oxygen, which belongs to the intersection of no definite volume and no definite shape in the Venn diagram.
Question 5
1 / -0

A definite volume but not a definite shape, is a property of:

A
solid

B
liquid

C
gas

D
all of the above

Solution

If the particles of a substance have enough energy to partially overcome inter-molecular interactions, then the particles can move about each other while remaining in contact. This describes the liquid state. In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
Question 6
1 / -0

What can $$x$$ be in the given Venn diagram?

A
Wax

B
Book

C
Honey

D
Oxygen

Solution

Honey has a definite volume but no definite shape because it is a liquid at room temperature. Hence, $$x$$ must be honey as it is formed by the intersection of definite volume and no definite shape in the Venn diagram.

Hence, the correct option is $$C$$
Question 7
1 / -0

On heating the solid _________.

A
particles gain energy

B
particles loses energy

C
energy remain constant

D
none of the above

Solution

On heating, the particles in the solid-state gain energy in the form of kinetic energy and start to vibrate faster and faster.
Question 8
1 / -0

On heating the solid ______________.

A
intermolecular attraction between particles increases.

B
intermolecular attraction between particles decreases.

C
intermolecular attraction between particles remains constant.

D
none of the above

Solution

On heating, the solid changes into liquid in which the kinetic energy of the molecules increases due to which, the inter molecular attraction between particles decreases and the molecules escapes from their positions.
Question 9
1 / -0

Change in the state of matter can be brought by changing :

A
temperature

B
pressure

C
A or B

D
none of these

Solution

Matter changes from one state to another by changing temperature or pressure. We can convert matter from one state to another by adding or removing energy(heat), i.e, by changing temperature. Or by changing the pressure we can bring the molecules closer or take them far apart. This also can change the state of the matter.
Question 10
1 / -0

Evaporation of a liquid _____________.

A
is dependent on its mass

B
increases with increasing pressure

C
is not affected by pressure

D
decreases with increasing pressure

Solution

Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance. The rate of evaporation can also increase with a decrease in the gas pressure around a liquid. Molecules like to move from areas of higher pressure to lower pressure. The molecules are basically sucked into the surrounding area to even out the pressure. Once the vapor pressure of the system reaches a specific level, the rate of evaporation will slow down.
