A thermosetting polymer, resin, or plastic, OFTEN called a thermoset, is a polymer that is irreversibly hardened by CURING from a SOFT solid or viscous LIQUID prepolymer or resin. Curing is induced by HEAT or suitable radiation and may be promoted by high pressure, or mixing with a catalyst.

iability of a historical phase comes from the critical evaluation of the resources which are divided into TWO parts that are literary and archaeological. ... EDICTS and inscriptions from the MAURYAN PERIOD and punch-marked coins from silver and copper are examples of archaeological SOURCES.

1:1.25Explanation:I KNOW not so SURELY

Unlike LIGHT, sound requires a medium to travel through. ... As the vibrations of the particles reach your ear, your ear DRUM receives the vibrations which the brain then INTERPRETS as sound. In the vacuum of space, there are no (or very, very few) particles to vibrate, so sound cannot travel in space.HOPE IT WILL HELPFUL FOR YOU ✌✌pls MARK as BRAINLIEST

हम पानी के बिना अपने दैनिक जीवन का नेतृत्व नहीं कर सकते। पानी हमारे शरीर के आधे से अधिक वजन को बनाता है। पानी के बिना, दुनिया के सभी जीव मर सकते हैं। पानी केवल पीने के लिए ही नहीं, बल्कि हमारे दैनिक जीवन के उद्देश्यों जैसे स्नान, खाना पकाने, सफाई और कपड़े धोने आदि के लिए भी आवश्यक है।Explanation:Have a NICE DAY

l be preferred out of all to BOIL a given QUANTITY of water. This is because it has the highest calorific VALUE in all and does not CAUSE pollution on burning

I THINK table SUGAR but what is the MEANING of ASPARTAME

Under certain conditions of pressure and temperature, most substances can exist in any one of three states of matter: solid, liquid, or gas. Water, for example, can be solid ice, liquid water, steam, or water VAPOR. The PHYSICAL properties of a substance often depend on its state. Gases, are simpler than LIQUIDS and solids in MANY ways.Explanation:

the following terms.A. AtmosphereB. TroposphereC Atmospheric humidityD. CombustionE. FuelF. PhotosynthesisA. The atmosphere of Earth is the layer of gases, commonly known as air, retained by Earth's gravity, surrounding the planet Earth and forming its planetary atmosphere.B. The troposphere is the lowest layer of Earth's atmosphere, and is also where nearly all weather conditions take place. It contains 75% of the atmosphere's mass and 99% of the total mass of WATER vapour and aerosols.C. Atmospheric humidity is the amount of water vapor carried in the air. It can be measured as vapor pressure, mixing ratio or specific humidity. Atmospheric water vapor is also the most important greenhouse gas in the atmosphere.D. Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a FUEL and an oxidant, usually atmospheric oxygen, that produces oxidized, OFTEN gaseous products, in a mixture termed as smoke.E. A fuel is any material that can be made to react with other substances so that it releases energy as heat energy or to be used for work. Fuels are also used in the cells of organisms in a process known as cellular respiration, where organic molecules are oxidized to release usable energy.F. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and MINERALS into oxygen and energy-rich organic compounds.

Miscibility /mɪsɪˈbɪlɪti/ is the property of two SUBSTANCES to mix in all proportions (that is, to fully DISSOLVE in each other at any concentration), forming a homogeneous SOLUTION. ... For EXAMPLE, WATER and ethanol are miscible because they mix in all proportions.

tion: Tearing of a paper is a physical change because when the paper is torn only the appearance of the paper is CHANGED and no NEW substance is formed. ... BURNING of paper is a chemical change when paper is BURNT the chemical composition of the paper is changed at the molecular level.

A BUSTED CRACKER cannot be CONVERTED back to its original state. Therefore its irreversible CHANGE

when ICE is heated the ice melts away and CHANGE its state. again if the ice is COOLED it come back into ice state. so, ice is melting and turning back into ice again.it is a reversible process. Melting of ice can happen in two instances that is due to climatic change and due to heating the ice. Heating of ice is a reversible process.Explanation:please MARK me as BRAINLIST

it is IRREVERSIBLE CHANGE

Jöns Jacob BERZELIUS was a Swedish CHEMIST. Berzelius is CONSIDERED, along with ROBERT Boyle, John Dalton, and Antoine Lavoisier, to be one of the founders of modern chemistry. He is KNOWN in Sweden as the "Father of Swedish Chemistry".The symbol of Krypton is KrHope it helps you!

Shiny METALS such as copper, silver, and gold are often used for decorative arts, jewelry, and coins.Strong metals such as iron and METAL alloys such as stainless STEEL are used to build structures, ships, and vehicles including cars, trains, and trucks.Mercury is used in thermometer and helps to CHECK the temperature. Aluminium are used as insulation wires.iron is used for construction

The post office has given a NUMBER of options to send letters from one place to another place which are known as methods of sending letters. Ordinary letter, REGISTERED letter, AEROGRAM, the INTERNET, POSTCARD, EMS, e-mail, fax, etc are some methods of sending letters.Explanation:fast is e-mail

mple, when a candle burns, it shows both physical and CHEMICAL change. Burning of the wax of the candle is a physical change as we can again make the candle using the MOLTEN wax. On the other HAND, burning if the thread of the candle is a chemical change as it is impossible to RENEW the thread.

If z = 4 it MEANS the atomic number of that element is 4 and therefore there are 4 no. of ELECTRONS present in the ATOM of that element. The element with atomic no. 4 is beryllium and the valency of beryllium is 2 DUE to the presence of 2 valence electrons.

s are one product of mechanically blending or mixing chemical substances such as elements and compounds, WITHOUT chemical bonding or other chemical change, so that each INGREDIENT substance retains its own chemical properties and makeup.[4] Despite the fact that there are no chemical changes to its constituents, the physical properties of a mixture, such as its melting point, may differ from those of the components. Some mixtures can be separated into their components by using physical (mechanical or thermal) MEANS. Azeotropes are one KIND of mixture that usually poses considerable difficulties regarding the separation processes required to obtain their constituents (physical or chemical processes or, even a blend of them).

tion:THREE things are REQUIRED in PROPER combination before ignition and combustion can take place---HEAT, Oxygen and FUEL.There must be Fuel to burn.There must be Air to supply oxygen.There must be Heat (ignition temperature) to start and continue the combustion process.
