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.

∙ 11y agoA change in phases, e.g. when water is boiled, the energy supplied is used to power the endothermic transition, i.e vapourise the water, instead of to increase the temperature of the water. (This is because the heat capacity is infinite at phase transitions)

∙ 8y agoEndothermic phase changes are melting, vaporization and sublimation.
In each of these, energy must be added to the substance to bring about the phase change.

How could you determine if a phase change in endothermic?
By a kinetic heat change.
What type of phase change does a substance absorb energy from its surroundings?
endothermic
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.
What is a endothermic change?
The change occured due to the endothermic reaction i.e. ( the reaction which requires heat to react ) is called endothermic change.
Even though the process is endothermic snow can subline Which tendency in nature accounts for this phase change?
1. a tendency toward greater entropy
How could you determine if a phase change in endothermic?
By a kinetic heat change.
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 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 vaporation a endothermic change?
Vaporization is an endothermic change.
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 is a endothermic change?
The change occured due to the endothermic reaction i.e. ( the reaction which requires heat to react ) is called endothermic change.
