No. Going from solid to liquid at constant temperature is an endothermic process. The required amount of energy is called "heat of fusion" of the material that changes state.

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 is the name of the process where a solid turns to liquid then gas?
To get a solid to a liquid you have to apply heat and melt it, and to get a liquid to a gas it has to evaporate. If you are talking about a solid going into a gas, then I don't know.
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 are 3 phase changes of exothermic?
freezing (liquid to solid), condensing (gas to liquid), and deposition (gas to solid)
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?
exothermic, because the water (H2O) was a liquid, heat had to have been taken out to make Ice (H2O) solid. Hope this helps!!
What happens to the heat in a system and in the surroundings in an exothermic reaction?
the system releases heat,meaning that energy is generatered.
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.
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.
What happens to the thermal energy of a substance during a change of state?
it will increase or decrease depending on the states. from solid --> liquid or liquid --> gas it is positive and endothermic, and thermal energy is increasing from liquid --> solid or gas --> liquid it is negative and exothermic, and thermal energy is decreasing
The process by which a solid becomes a liquid?
A solid becomes a liquid by the solid's molecules spreading farther apart until the point that it becomes a liquid because the temperature increases which causes the moecules to separate until liquid.
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.
Is liquid to a gas endothermic or exothermic?
It is exothermic. The gas must release energy to its surrounding to become a liquid.
