Is gas to liquid endothermic or exothermic?
The liquid to gas phase transformation (evaporation) is an endothermic process. It requires heat to be accomplished. The gas to liquid phase transformation (condensation) is an exothermic process. The vapor releases heat while condensing into a liquid.
Is clingfilm a solid or liquid?
it is a gas
If you place a solid in a liquid will ether sink?
That depends on the relative densities of the solid and the liquid. If the solid is denser than the liquid, the solid will sink. If the liquid is denser, the solid will float.
When water changes from a liquid state to a solid state we say it as?
gas -> liquid = condensation liquid -> solid = solidification (freezing) solid -> gas = sublimation gas -> solid = deposition solid -> liquid = melting liquid -> solid = vaporization
What are the observable changes in freezing water?
liquid to solid
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.
What three phase changes ar exothermic?
Gas to liquid (condensation)Liquid to solid (freezing)Gas to solid (desposition)
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 h20 liquid- H2O solid endothermic?
The process of turning liquid water (H2O) into solid ice is exothermic, meaning it releases heat. This is because forming hydrogen bonds in the solid phase is more stable than in the liquid phase, resulting in a net release of energy.
Is Liquid water turning to ice a endothermic or exothermic process?
The process of freezing is an exothermic process. Particles in a liquid have more energy than those in a solid, hence they vibrate / move more. Therefore, to turn a liquid into a solid, energy needs to be taken out of the liquid. This means energy is given off to its surroundings, making it an exothermic process.
Is solidification exothermic or endothermic?
Solidification is an exothermic process because it involves the release of heat as a substance changes from a liquid to a solid state. This heat is typically released as the molecules in the liquid slow down and form a more ordered solid structure.
Is freezing an example of endothermic or exothermic change?
Freezing is an exothermic process because heat is released when a substance changes from a liquid to a solid, lowering the temperature of the surroundings.
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.
Is liquid exothermic or endothermic?
Depends, Liquid can be both endothermic and exothermic, for example water, if you freeze water and put it in room temperature it will be endothermic, meaning it will absorb the heat form the room. And if you Boil water and put it in a cold place it will become exothermic because its releasing the heat.
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 molten metal solidifies exothermic or endothermic?
The solidification of molten metal is an exothermic process. During this phase change, the metal releases heat as it transitions from a liquid to a solid state. This release of heat occurs because the molecules in the liquid metal lose energy and arrange themselves into a more stable solid structure.
Is freezing an example of an exothermic chemical change?
No because in an exothermic change energy is released not taken in. Melting would be an example of exothermic change.
