Is the sublimation of carbon dioxide exothermic?
sublimation doesnt nessicarily have anything to do w/ temperature. it is observed in substances such as CO2 (Carbon Dioxide) which have high vapor pressure and low intermolecular force. i take no responsibility for any harm done to u or whoever tests this in some krazy way reading my response to this question....
What are 3 phase changes of exothermic?
Solid to liquid (melting): This phase change requires energy to break the intermolecular forces holding the solid together, resulting in an endothermic process. Liquid to gas (vaporization): This phase change requires energy to overcome the intermolecular forces between liquid molecules, also an endothermic process. Gas to liquid (condensation): This phase change releases energy as gas molecules lose kinetic energy, forming stronger intermolecular forces in the liquid phase, and is an exothermic process.
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.
When solid lead chloride dissolves in hot water is this endothermic or exothermic?
The dissolution of solid lead chloride in hot water is an endothermic process because energy is absorbed to break the bonds holding the solid together. This energy is needed for the solid to transition into freely moving ions in solution.
Is solid carbon dixiode going to CO2 gas absorbing or releasing energy?
The process of solid carbon dioxide (dry ice) turning into CO2 gas is endothermic, meaning it absorbs energy from its surroundings. This absorption of energy causes the solid carbon dioxide to sublimate directly into a gas without passing through a liquid phase.
What are 2 phase changes that are endothermic or absorbing energy?
Two phase changes that are endothermic or absorbing energy are melting (solid to liquid) and vaporization (liquid to gas). During these phase changes, energy is absorbed to break the intermolecular forces holding the particles together, allowing them to move more freely in their new state.
Is solid to gas endo or exo?
Heat is required to solid for melting and to liquid for evaporation so these are endothermic processes.
Is sublimation exothermic or endothermic?
Sublimation is an endothermic phase transition from solid to gaseous state.
What are the three phase changes?
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.
Is burning gasoline an exothermic process or an endothermic process?
Solid to gas (sublimation) is endothermic (takes in heat).In other words:A phase change from the solid state to the gas state is endothermic.Sublimation is endothermic (takes in energy).Heat energy must be provided to make it work.When there is a change of state from a solid to a liquid, a solid to a gas, or a liquid to a gas, at a constant temperature, the process is endothermic NOT exothermic. It requires energy to break the intermolecular forces that keep the molecules together, and that reduces the temperature - heat is taken in.
Is heat taken away or added in sublimation?
Sublimation is an endothermic physical change (heat is needed).
What is happening to energy in sublimation?
Sublimation is an endothermic phase transition.Sublimation is the transformation of a solid in a gas, directly, and need energy for this.
Is the sublimation of carbon dioxide exothermic?
sublimation doesnt nessicarily have anything to do w/ temperature. it is observed in substances such as CO2 (Carbon Dioxide) which have high vapor pressure and low intermolecular force. i take no responsibility for any harm done to u or whoever tests this in some krazy way reading my response to this question....
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 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 is it called when a liquid reacts with a solid the temperature dropped and a gas is released?
An endothermic reaction usually exhibits a drop in temperature.
Is boiling an egg endothermic or exothermic?
It is endothermic as the water mus gain energy to go from a liquid to a gas.
