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.
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.
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.
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.
