In liquids, particles keep changing their neighbors while sliding past each other, confined to the shape of the vessel. In gases, particles are free, separated by large distances, and move rapidly in straight lines. Temperature is a measure of the average motion energy of the particles in both liquids and gases.
The movement of particles in liquids and gases is different due to their states of matter. In liquids, particles are held together by attraction, allowing them to slide smoothly past each other and change neighbors, but they remain confined to the shape of the vessel they are in. This is a less energetic state of movement.
On the other hand, in gases, particles are broken free of bonds. They travel in straight lines and are separated by large distances compared to their size, colliding with each other or the walls of the container. They are in a more energetic state and rapidly occupy all the accessible volume, hence gases can expand without limit to fill their containers.
At a microscopic level, the temperature of a liquid or gas is a measure of the average motion energy of the particles making it up - the hotter the liquid or gas, the more rapid the motion of its molecules or atoms.

Explanation:
(A)
The mass and volume are thephysical properties that define matter. A matter is anything that can be seen or touched and is said to have mass, volume, density, and occupies space.
A matter is a substance present in the universe that occupies space and is said to have a definite volume and mass. Based on its physical arrangement and composition the matter can be gas, liquid, plasma, or solid.
The mass, volume, and density define the matter and its particles with specific mass and sizes due to the presence of sub-atomic particles like neutron, electron, and proton.
The amount of matter in the universe can be measured in kilograms and grams as mass, and the space occupied by it in cubic meters (m³) as volume.
Therefore, the matter is said to have volume and mass.

Many insulating materials contain spaces filled with air because ; Air is a poor conductor of heat and electricity
Insulators are materials that do not allow the easy passage of heat or electricity through them. they are used to protect users from direct exposure to electricity and heat and also for the protection of equipment's at home and at work places.
Insulators are generally bad conductors of heat and electricity. some examples of insulators are ;
They are all very good insulators. but the most commonly used insulator in electrical installations is Porcelain
Hence we can conclude that many insulating materials contain spaces filled with air because Air is a poor conductor of heat and electricity.

The concentration of the hydrogen dissociated into the solution gives the pH. When the solution has a pH of 5.6 then, the concentration of H⁺ is 2.51 × 10⁻⁶.
The estimation of the acidic and alkalinity of the solution based on the amount of the dissociated hydrogen or the hydronium ions in the solution gives the pH.
It is measured with the help of the pH scale that indicates the range of the acids and bases along with neutral. The formula of the pH includes the negative logarithm of the hydrogen ion concentration. pH is calculated as,
pH = - log [H⁺]
Given,
pH = 5.6
Substituting values above the concentration are calculated as,
pH = - log [H⁺]
5.6 = -log [H⁺]
[H⁺] = 10⁻⁵°⁶ ≈ 0.0000025
= 2.51 × 10⁻⁶
Therefore, the hydrogen concentration in solution with pH 5.6 is equivalent to 2.51 × 10⁻⁶.

Answer:
Hi there!
The answer to this question is 2.5118X10^-6
Explanation:
The formula to solve this is 10^-pH
Answer:For Fe
Z=26
Explanation:
1s2 2s2 2p6 3s2 3p6 4s2 3d6
Are there 26 electrons here? Why should there be 26?
So going back to the inert gas, argon ( Z=18 ), we get
[Ar] 4s2 3d6
