Which of the following forms a new substance melting freezing evaporating burning?
Burning chemically alters a substance, creating different / new substances as a result. Melting, freezing, and evaporating are all different phases of the same substance.
Which of the following is endothermic a dry ice evaporating b a sparkler burning c the reaction that occurs in a chemical cold pack often used to ice athletic injuries?
The reaction that occurs in a chemical cold pack used to ice athletic injuries is endothermic, as it absorbs heat from its surroundings to lower the temperature. Dry ice evaporating and a sparkler burning are both exothermic processes where heat is released.
Is burning sugar endothermic?
No, burning sugar is exothermic because it releases energy in the form of heat and light. The chemical reaction between sugar and oxygen produces carbon dioxide and water, along with energy that is released in the form of heat and light.
What is an example of oxidation water evaporating sugar melting paper burning or all of the above?
An example of oxidation would be paper burning because it involves a chemical reaction where paper combines with oxygen in the air to produce heat and light. Water evaporating and sugar melting are physical changes, not chemical reactions involving oxidation.
Is smoke an example of condensation?
No, smoke is not an example of condensation. Smoke is a collection of airborne solid and liquid particles produced from combustion or burning materials. Condensation is the process of a gas changing into a liquid state.

Is burning alcohol an exothermic or endothermic process?
Exothermic
What is a piece of rusting metal doing?
A) burning B) evaporating C) fermenting; I'm not sure, its a multiple choice. A) burning B) evaporating C) fermenting; I'm not sure, its a multiple choice.
How does a gas form?
it is formed by either water evaporating or somthing burning
Is a wick necesarry in a burning candle?
Yes that is what burns the melting wax prolongs the burning time by slowly evaporating
Is burning fat endothermic?
yes but you have to stop eating like a pig
Is burning a match an endothermic or exothermic change?
Burning a match is an exothermic change because energy is being released.
Is paper burning with a bright flame a exothermic reaction or endothermic reaction?
Reactions with oxygen (air) involved, like burning paper, are exothermic. Exception: formation of many nitrogen-oxygen compounds (NOx) are endothermic.
The burning of a fuel transforms which energy?
The burning of a fuel transforms chemical energy into heat and light energy.
Is burning sugar endothermic?
No, burning sugar is exothermic because it releases energy in the form of heat and light. The chemical reaction between sugar and oxygen produces carbon dioxide and water, along with energy that is released in the form of heat and light.
Is paper burning with bright flames exothermic or endothermic?
Exothermic, for within an endothermic (situation) there would be a drop of temperature *excuse my spelling if you would* , therefore to continue burning it will need to absorb the heat, where as exothermic reactions energy will be released as heat.
