What are 3 phase changes of exothermic?
freezing (liquid to solid), condensing (gas to liquid), and deposition (gas to solid)
When the temperature changes cause of a reaction is it exothermic or endothermic?
It is exothermic
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
Classify the burning of natural gasses in exothermic or endothermic changes?
The burning of natural gas is an exothermic process.
An ionic bond will form only if the sum of the energy changes is?
exothermic
Which phase changes are endothermic?
Based on chemical properties exothermic phase changes are those that release energy. The exothermic phase changes are gas--> liquid, liquid --> solid, and gas--> solid. Looking at a phase diagram if you are going up the "stairs" the conversions require energy going down the "stairs" energy is released.
What phase changes are exothermic?
Condensation (g to l), solidification (l to s) and deposition (g to s).
What are 3 phase changes of exothermic?
freezing (liquid to solid), condensing (gas to liquid), and deposition (gas to solid)
What three phase changes ar exothermic?
Gas to liquid (condensation)Liquid to solid (freezing)Gas to solid (desposition)
Which phase change is an exothermic process?
Change of phase from gas to liquid to solid are exothermic reaction. Condensation, deposition and freezing are exothermic processes that undergo change in phase.
When the temperature changes cause of a reaction is it exothermic or endothermic?
It is exothermic
Is solid exothermic or endothermic?
A solid is itself neither endothermic or exothermic. However the phase change from liquid to solid will likely be exothermic.
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
What is an exothermic phase change?
condensation freezing and deposition
Is a liquid endothermic or exothemic?
A liquid on its own cannot be described as either endothermic or exothermic. The terms endothermic and exothermic are the names of two opposite process reactions. An endothermic reaction absorbs heat and and exothermic reaction gives off heat. A liquid can be involved in either an endothermic reaction or in an exothermic reaction. If you are evaporating a liquid from its liquid phase to its gas phase, then the reaction is usually endothermic and vice versa, going from the gas phase to the liquid phase, the reaction is usually exothermic.
What contrast endothermic and exothermic changes?
Exothermic: release of heat Endothermic: absorption of heat
What is an exothermic process?
An exothermic change is a change that releases heat. Combustion is an exothermic chemical reaction.Adding water to sulfuric acid releases heat, called exothermic heat of mixing. Exothermic changes are the opposite of endothermic changes that absorb heat when they take place.
