A Correct answer
Explanation

The kinetic theory considers all matter( substances) to be made up of particles which are in continuous motion. 


On raising the temperature, the solid-state, in which the particles are closely packed in regular arrangement changes into the liquid sate where particles are closely packed in a random arrangement. this process is called melting.

Hence, it is a true statement.

When a substance is heated kinetic energy of particles decreases.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Theoretically, heating a solid to higher and higher temperatures changes its phase to a liquid, and finally to a gas.
A solid consists of low kinetic energy vibrating particles locked into position by interparticle attractive forces. When heat is applied, energy is absorbed and the particles start vibrating more vigorously.

Which produces more burn, steam or boiling water?

  1. Steam

  2. Boiling water

  3. Both produces same burn

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

Water vapour at 373K has more energy than water at 373K as the steam has absorbed latent heat of vaporisation to change the state. Therefore the more burning sensation.

The chemical reaction between quicklime and water is characterised by:

  1. Evolution of hydrogen gas

  2. Suspension of slaked lime in water

  3. Change in temperature of mixture

  4. Change in colour of product
Reveal answer Fill a bubble to check yourself
B,C Correct answer
Explanation

Quicklime when added to water, it reacts with water chemically and form a suspension of slaked lime in water and produce heat energy. So it also results in an increase in temperature of the mixture.

$CaO+{ H } _{ 2 }O\rightarrow Ca{ (OH) } _{ 2 }+Heat$

State having indefinite shape but definite volume is:

  1. solid.

  2. liquid.

  3. gas.

  4. liquid and gas.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Solid has highest inter-molecular force of attraction. Liquids has inter-molecular force of attraction less than solid but greater than Gas. So, it has indefinite shape but definite volume.


Hence, the correct option is $B$.

Diffusion is negligible in case of:

  1. solid.

  2. liquid.

  3. gas.

  4. solid and liquid.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Due to high inter-molecular force of attraction and very small inter-molecular spaces diffusion is negligible in solid.

Particle in solid have lowest kinetic energy so they do not move.


Hence, the correct option is $A$.
