States of Matter Questions
-
Liquid
-
Gas
-
Solid
-
Both (2) and (3)
C
Correct answer
Explanation
In science, the common name of gases and liquids is fluids.
As solid does not flow, therefore, it is not a fluid.
-
Water
-
Air
-
Sugar solution
-
None of these
A
Correct answer
Explanation
Water is a compound and compounds do not show the properties of their constituents.
-
Element
-
Compound
-
Mixture
-
Suspension
A
Correct answer
Explanation
An element is a pure substance with only one kind of atoms.
An element is a material that consists of a single type of atoms while a compound consists of two or more type of atoms.
-
a mixture
-
a compound
-
an element
-
a colloid
-
evaporation
-
sublimation
-
diffusion
-
decantation
C
Correct answer
Explanation
If we open a bottle of perfume, its fragrance spreads in the entire room within a short time due to the process of diffusion.
-
sublimation
-
evaporation
-
diffusion
-
condensation
A
Correct answer
Explanation
The process of converting solid directly into gaseous state on heating is called sublimation.
-
Gas
-
Liquid
-
Solid
-
None of these
C
Correct answer
Explanation
Solid is least compressible as compared to gas and liquid.
-
colour, odour and taste
-
hardness, solubility and density
-
melting point and boiling point
-
All of these
D
Correct answer
Explanation
The various physical properties of a substance may include colour, odour, taste, hardness, solubility, density, melting point and boiling point.
-
water
-
steam
-
ice
-
All of the above
C
Correct answer
Explanation
Ice has the least intermolecular space as compared to water and steam.
C
Correct answer
Explanation
Out of air, sea water, soil and ice, ice is not a mixture as it is frozen water and is in solid state.
-
evaporation
-
condensation
-
diffusion
-
sublimation
B
Correct answer
Explanation
The process of converting gas into liquid, on cooling, is called condensation.
-
hoar frost
-
sublimation
-
condensation
-
freezing
-
solidification
A
Correct answer
Explanation
The process of direct conversion of vapour into solid is called hoar frost.
-
between the upper and lower critical temperature and cooled in still air
-
above the upper critical temperature and cooled in furnace
-
above the upper critical temperature and cooled in still air
-
between the upper and lower critical temperature and cooled in furnace
C
Correct answer
Explanation
Normalizing involves prolonged heating just above the critical temperature to produce globular form of carbine and then cooling in air.
-
Vitrification
-
Hyperhydricity
-
Cryoprotectant
-
Habituation
A
Correct answer
Explanation
Vitrification is the process of transforming a substance into a glass-like amorphous state, which is a common technique in cryopreservation to prevent ice crystal formation.
-
Mineral Water
-
Orange juice
-
Milk
-
Water
A
Correct answer
Explanation
Mineralwasser is the German term for mineral water, which is carbonated water.
