is Absorbs If you are asking if a change of state is why a reaction may be endothermic, is not always true. It simply depends on what the change of state is to and what it is from, ex: a change from liquid to solid is usually exothermic because it losses energy as the particles slow down and draw near to eachother... and the opposite occurs from solid to liquid (or liquid to gas).

∙ 9y agoA change of state reaction that absorbs energy is called endothermic. The term is derived from the words endo- which means 'within' and 'therm' which means 'hot'.

∙ 12y agoWhen a chemical reaction occurs and the temperature has decreased, it's called an endothermic reaction. However, if the temperature increases then we call it an 'exothermic' reaction.

What are the 3 phases of energy metabolism?
Glycolysis , krebs cycle and electron transport
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.
A chemical reaction that requires a net input of energy?
"Activation Energy reactions"; Endothermic reactions require energy.
Which phases of a typical bacterial growth curve illustrates a log change in cell number. Oviously log or growth phase is logarithmic. Is the death phase a negative log change?
Exponential
What kind of reaction is photosynthesis?
Photosynthesis is a Endergonic/Endothermic reaction.
How could you determine if a phase change in endothermic?
By a kinetic heat change.
Which phase change is endothermic?
The 3 types of endothermic phase changes are the movement from solid to liquid, the movement from liquid to gas, and the movement form gas to plasma. Endothermic is the absorbing of heat.
What type of phase change does a substance absorb energy from its surroundings?
endothermic
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.
Is sublimation exothermic or endothermic?
Sublimation is an endothermic phase transition from solid to gaseous state.
What are the 3 phases of energy metabolism?
Glycolysis , krebs cycle and electron transport
How does an endothermic process differ from an exothermic process?
An endothermic phase change is when the substance absorbs energy from its surroundings (melting, vaporization).In an exothermic phase change the substance releases energy to its surroundings (freezing, condensation)..
What statement about the energy of a phase change is true?
Melting is an endothermic change, because ice absorbs energy from its surroundings as it melts.
Is melting an ice cube an example of endothermic processes?
Yes, the ice cube must absorb thermal energy from its surroundings to undergo the phase change, so the process is in fact endothermic.
Is vaporation a endothermic change?
Vaporization is an endothermic change.
Is sublimation a phase change?
Sublimationis the process of transition of a substance from the solid phase to the gas phase without passing through an intermediate liquid phase. Sublimation is an endothermic phase transitionthat occurs at temperatures and pressures below a substance's triple point
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.
