Explain why gases make better thermal insulators than solids or liquids.​

Physics
2 answers:
Fantom [35]2 years ago

Answer:

Solids conduct heat better than liquids, which are in turn better conductors than gases. ... Thus liquids are usually poor conductors of heat. In a gas, the particles are far apart, making energy transfer by collision very inefficient. Thus gases, like air, are very poor conductors of heat.

Gases make better thermal insulators and is due to the more inter molecular distance, and the weak forces among particles of gases.

<u>Explanation:</u>

The speed of heat transfer by conduction is varies for different materials. If the materials is less dense they are better insulators and if the material is more dense its insulating property is very less.

An insulator is a material that is poor conductor of heat. In gases the inter molecular forces of attraction is weakest. The particles are very apart from each other.

The efficiency of a light source is the percentage of its energy input that gets radiated as visible light. if some of the blue
Anestetic [448]

The efficiency of a light source is the percentage of its energy input that gets radiated as visible light if some of the blue light in an led is used to cause a fluorescent material to glow the overall efficiency of the LED decreases.

How efficient is LED?

Different wavelengths that correlate to different visible colours are used in LED light therapy. Various shades pierce the skin at different rates.

  1. Your skin's outermost layer is impacted by blue light.
  2. Yellow light is more enveloping.
  3. Red light penetrates your skin more deeply.
  4. The deepest penetrating light is near-infrared.

Different LED hues have various effects. For instance, according to experts red LED light therapy has the potential to reduce inflammation and boost collagen formation, which declines with age and is crucial for maintaining youthful-looking skin.

Acne-causing bacteria may be destroyed by a blue LED light therapy (P. acnes).

Hence the answer is the overall efficiency of the LED decreases.

How do two sublevels of the same principal energy level differ from each other
Colt1911 [192]

Each energy sublevel corresponds to an orbital of a different shape.

Explanation:

Two sublevels of the same principal energy level differs from each other if the sublevels corrresponds to an orbital of a different shape.

  • The principal quantum number of an atom represents the main energy level in which the orbital is located or the distance of an orbital from the nucleus. It takes values of n = 1,2,3,4 et.c
  • The secondary quantum number gives the shape of the orbitals in subshells accommodating electrons.
  • The number of possible shapes is limited  by the principal quantum numbers.

Take for example, Carbon:

                      1s² 2s² 2p²

   The second energy level is 2 but with two different sublevels of s and p. They have different shapes. S is spherical and P is dumb-bell shaped .
