Multiple choice chemistry matter in our surroundings diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

Liquids and gases ....................... on heating.

  1. contract

  2. expand

  3. melt

  4. none of above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Liquids and gases expand when they are heated. This is because the particles in liquids and gases move faster when they are heated than they do when they are cold. As a result, the particles take up more volume. This is because the gap between particles widens, while the particles themselves stay the same size.

Which of the following is a type of latent heat?

  1. Latent heat of fusion

  2. Latent heat of vaporization

  3. Both a and b

  4. None of above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The latent heat is used in change of states of matter, such as from solid to liquid or from liquid to gas without rising in temperature. When solid changes into liquid, the heat required for changing the state without rise in temperature is called the Latent Heat of Fusion. When liquid changes into gas because of rise in temperature, the heat required changing the state without rising in temperature is called the Latent Heat of vaporization.

................... reflects all heat, .................... absorbs all heat.

  1. White, black

  2. Black, white

  3. White, yellow

  4. None of above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A black object absorbs all wavelengths of light and reflects none. Objects that are white, on the other hand, reflect all wavelengths of light and therefore absorb the least heat.

Which of the following is a good conductor of heat?

  1. Aluminium

  2. Sulphur

  3. Chlorine

  4. Oxygen
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Heat is thermal energy. It can be transferred from one place to another by conduction. Metals are good conductors of heat, but non-metals and gases are usually poor conductors. Poor conductors are called insulators.

Which of these is a property of a solid.

  1. Has a definite shape

  2. Has a definite volume

  3. Doesn't have a fixed shape

  4. Doesn't have a fixed volume
Reveal answer Fill a bubble to check yourself
A,B Correct answer
Explanation

A solid has a definite volume. It also has a definite shape.
The intermolecular forces in the case of a solid are very high compared to liquids and gases and hence a solid are held together tightly. Thus, a solid has a definite shape.


Hence, the correct options are $A$ and $B$

Which of these is a property of a gas.

  1. Has a fixed volume

  2. Has a fixed shape

  3. Doesn't have a fixed volume

  4. Doesn't have a fixed shape
Reveal answer Fill a bubble to check yourself
C,D Correct answer
Explanation

The intermolecular forces in the case of gas are very very weak and hence the gas molecules are not at all held tightly. Thus a gas doesn't have a fixed shape at all.
Gases do not have a fixed volume too. It has the volume of the container in which it is kept.


Hence, the correct options are $C$ and $D$

Look at the classification table below. Which of the following sets of headings is correct?

I II III
Oil Snow Wind
Paint Crayon Oxygen

  1. (I) Gas (II) Liquid (III) Solid

  2. (I) Liquid (II) Gas (III) Solid

  3. (I) Liquid (II) Solid (III) Gas

  4. (I) Solid (II) Gas (III) Liquid
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Oil and paint exist in the liquid state, crayon and snow are in the solid-state while wind and oxygen exist in the gaseous state. Hence, I - liquid, II - solid and III - gas.

Hence, the correct option is $C$.

Mechanical work is specially important in systems that contains :

  1. gas-liquid

  2. liquid-liquid

  3. solid-solid

  4. amalgam
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mechanical work is important in systems that undergo appreciable change in volume. 


Since solids are incompressible, hence mechanical work is insignificant in solids. 

However, gases and liquids(to some extent) undergo appreciable change in volume and hence, mechanical work becomes important in case of gases and liquids.

Therefore, the option is A.

Multiple choice chemistry matter in our surroundings diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

Which is not a property of solids

  1. Solid are always crystalline in nature

  2. Solid have high density and low compressibility

  3. The diffusion of solid is very slow

  4. Solids have definite volume
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

solids can be crystalline as well as amorphous in nature.

solids have definite volume.
solids are nearly compressible..
diffusion rate is almost zero for solids.
also solids have high density.
 
so the correct answer is A option.as it is the only option which is wrong here.
