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.
What is the difference between freezing and deposition?
Freezing is Liquid to Solid.Deposition is Gas to Solid.They are both Exothermic.
Is sublimitation exothermic?
Sublimation is an endothermic process because it requires energy input to change a substance from a solid directly to a gas without passing through the liquid phase.
Does heat change a solid to a liquid or gas?
Let's consider the case of ice. Ice is a solid. When heated, it gets transformed to water. Water is a liquid. Further heating changes water into gas. Thus, heat can change a solid into both liquid and solid form.
Is a feather a liquid or solid or gas?
a feather is a solid

What three phase changes ar exothermic?
Gas to liquid (condensation)Liquid to solid (freezing)Gas to solid (desposition)
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 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.
Why is the diffusion of a gas in a vacuum exothermic?
It is exothermic because the gas is expanding. Most processes that have to do with expansion are exothermic/
When you go from a gas to a solid is it endothermic?
Endothermic is the gaining of internal heat from the sun or hot objects cold blooded animals use this and im pretty sure that there is no word for gas to a solid im pretty sure that is physically impossible
If and Egg cooks in boiling water and turns the yolk to a solid is it an endothermc or exothermic?
exothermic
Is liquid to a gas endothermic or exothermic?
It is exothermic. The gas must release energy to its surrounding to become a liquid.
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.
Is dry ice sublime exothermic?
Yes, the process of dry ice sublimation is exothermic. When dry ice (solid carbon dioxide) changes directly into gas without passing through the liquid phase, it releases heat energy, making it an exothermic process.
How do you describe each phase change?
Endothermic phase changes - the substance is gaining energy (being heated) and the molecules are getting more active.- solid to liquid: melting- liquid to gas: vaporization- solid to gas: sublimationExothermic phase changes - the substance is losing energy (cooling) and the molecules are slowing down.- gas to liquid: condensation- liquid to solid: freezing- gas to solid: depositionMemory helper: exo is like exit, and the heat energy exits the substance during an exothermic phase change.
What is the difference between freezing and deposition?
Freezing is Liquid to Solid.Deposition is Gas to Solid.They are both Exothermic.
