Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
When the temperature changes cause of a reaction is it exothermic or endothermic?
It is exothermic
Classify the burning of natural gasses in exothermic or endothermic changes?
The burning of natural gas is an exothermic process.
When clothes are drying is it an endothermic or an exothermic reaction?
The combustion is exothermic.
How can you tell the difference between an endothermic and exothermic reaction?
You can generally tell by changes in temperature, whether you have an exothermic reaction which produces heat, or an endothermic reaction which consumes heat.
Is freeezing endothermic or exothermic?
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Contrast endothermic and exothermic reactions?
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.
Is silicon endothermic or exothermic?
Silicon is an element - endothermic or exothermic is meaningless.
Is decomposition of phosphorus pentachloride endothermic or exothermic?
Exothermic reaction.
Contrast the forming and breaking of chemical bonds in terms of energy changes?
The formation of chemical bonds releases energy. It is an exothermic process. The breaking of chemical bonds takes energy. It is an endothermic process.
Is a candle a endothermic or exothermic change?
exothermic- because exothermic gives off heat and endothermic is cold
An endothermic reaction causes the surroundings to?
An endothermic reaction is one that absorbs heat energy from the surrounding environment. Therefore, an ongoing endothermic reaction will cause its surroundings to become colder. In contrast, an exothermic reaction radiates heat energy into its surroundings, which will cause the ambient environment to get warmer.
