What is a good insulator and why
Polystyrene and plastic foam are both used as insulators as they have small air bubbles trapped inside them.
This makes them very good insulators because heat energy can’t flow through them.
The same idea is used to keep the inside of buildings warm..
What does insulation mean in science
Insulation means creating a barrier between the hot and the cold object that reduces heat transfer by either reflecting thermal radiation or decreasing thermal conduction and convection from one object to the other. Depending on the material of the barrier, the insulation will be more or less effective.
What is the synonym of insulate

Why do we need insulation
Insulation will help you keep the desired temperature in your house all year round, protecting it against cold in winter and excess heat in summer. Insulation is also useful to reduce noise pollution. A well-insulated house is very energy efficient and will need very little additional heating and cooling.

Which heat insulator is poor
Materials that are good conductors of thermal energy are called thermal conductors. Metals are very good thermal conductors. Materials that are poor conductors of thermal energy are called thermal insulators. Gases such as air and materials such as plastic and wood are thermal insulators.
What insulation means
1 : material that is used to stop the passage of electricity, heat, or sound from one conductor to another. 2 : the act of insulating : the state of being insulated insulation of wires. insulation. noun.
Does thermal mean heat
Thermal means caused by or related to heat or temperature. The word thermal is used in science to describe a specific kind of energy: thermal energy. Thermal energy is produced by heating up molecules and atoms until they move fast enough to collide into each other.
What does insulate mean
transitive verb. : to place in a detached situation : isolate especially : to separate from conducting bodies by means of nonconductors so as to prevent transfer of electricity, heat, or sound.
What does non thermal mean
: not produced by heat specifically : of, relating to, or being radiation having a spectrum that is not the spectrum of a blackbody.
Is cold the opposite of thermal energy
Heat is the amount of energy that is transferred from one place to another because of a temperature difference. Is cold the opposite of thermal energy of the lack of it? Lack of it.

What is insulation in construction
Essentially, insulation is any material used to fill the spaces (including little gaps, crevices and hard-to-reach places behind walls, above ceilings, etc.) of your home to reduce heat flow by reflection and/or absorption.
What is best insulation
The best types of home attic insulation are open cell spray foam, fiberglass, and cellulose.Cellulose is the oldest insulation material used for not only the attic but other areas of the home as well. … Fiberglass is another traditional insulation material that consists of extremely fine glass fibers.More items…•Jun 1, 2020

Why is plastic a good thermal insulator
They don’t have free electrons moving around (delocalised electrons) so they can’t conduct heat and electricity which gives them a property of good insulators. The insulators stop us having an electric shock because they don’t conduct electricity as we use them to insulate metal wires and other metallic things. 1.
What makes something a good insulator
Insulators have strong bonds that hold their particles rigidly in place. … This prevents particles from gaining energy and increasing the temperature. Wool, dry air, plastics, and polystyrene foam are all examples of good insulators. Materials that do not insulate well are called conductors.
How do you spell insulated
Correct spelling for the English word “Insulated” is [ˈɪnsjʊlˌe͡ɪtɪd], [ˈɪnsjʊlˌeɪtɪd], [ˈɪ_n_s_j_ʊ_l_ˌeɪ_t_ɪ_d] (IPA phonetic alphabet).
What is the opposite of thermal insulators
The opposite of a thermal conductor is a thermal insulator. An insulator is a very poor conductor. Because we are warm-blooded (and like to stay warm), insulators are important. When we touch a cool piece of foam insulation, it does not take energy away from us because it is not a good conductor.
What does well insulated mean
Conventional insulation materials such as styrofoam or wool are not fully able to prevent the exchange of heat because air or other gases are trapped in their interstices. …
