What is the driving force that causes matter to change phase?
A change in temperature. As temperature increases a solid will melt into a liquid. A liquid will evaporate into a gas. As the temperater decreases a gas condenses into a liquid. A liquid freezes to solid. Sometimes the liquid phase is skipped altogether. The temperature at which phase transitions occur vary for different chemicals due to different chemical structures and bonding. Also some compounds will decompose, rather than melt.
What would happen if you cool the gas?
it would turn into liquid because molecules gain energy and join forces as they are cooled.
Change of water from a liquid to a gas state?
boiling? At around 100 degree centigrade, the heat provides the liquid water with enough kinetic energy that the particles gain so much energy that the hydrogen bonds break and the water than changes to water vapour as the particles spread out and travel much faster.
The change of water from a gas to a liquid?
The process of changing liquid water into a gas is called evaporation. Energy is added to the liquid water - generally in the form of heat. When enough energy is added, it allows the most energetic molecules at the surface of the liquid to break free of the liquid and enter the gas phase. The more energy that is added, the more water molecules will have enough energy to move into the gas phase. If enough energy is added, all the molecules will leave the liquid and from then on adding energy will just make the gas warmer. Another way to change liquid water into gas is to drop the pressure above the liquid. In this case, it takes less energy for the molecules in the liquid to get away from the liquid so some of them will already be energetic enough to get away. Any mass of liquid water will have a range of energies for the molecules, some will be low energy, others high energy with each collision between the molecules, they either gain or loose energy. If they gain enough energy, they can become energetic enough to escape the liquid as a gas. The higher the pressure, the more energy is required to become a gas. If the liquid water is in contact with some gas - air for example. The liquid will evaporate until the gas is saturated with water vapor. At that point the rate of water molecules dropping out of the gas back into the water (because they don't have enough energy to stay in the gas) is equal to the rate of water molecules escaping from the liquid to become gas. This point is also known as "equilibrium".
Can matter change into a gas to a solid?
matter can be changed from a solid to a liquid and then to a gas because a solid can melt and turn into liquid and then the liquid can evaporate and turn into a gas
When a solid changes to a liquid does it speed up or slow down?
When a solid changes to a liquid, the particles gain energy and start moving faster, causing the solid to melt into a liquid. So, in this process, the particles speed up.
What is the temperature at which a liquid changes to a solid called is there a gain or a loss of energy?
Such a temperature is known as Freezing point of the liquid, during the freezing process the system losses the energy.
Do molecules gain or lose energy from melting?
When matter melts (changes from a solid to a liquid state), its molecules move faster, meaning they are gaining energy.
By removing heat what happesn 1. a liquid changes to a solid. 2 a solid changes to a liquid. 3 a liquid changes to a gas. 4. a solid changes to gas?
A liquid changes to a solid when heat is removed, as the molecules lose energy and come together in a more ordered structure. A solid changes to a liquid when heat is applied, causing the molecules to gain energy and break free from their fixed positions. A liquid changes to a gas when heat is added, increasing the molecular motion and allowing them to escape into the vapor phase. A solid changing directly to a gas is called sublimation and occurs when the substance bypasses the liquid phase by gaining enough energy to transition from solid to gas.
What is the temperature at which a solid changes to a liquid called is there a gain or a loss of energy?
this process is the process of gaining thermal energy. As any matter changes state from solid to any other form it will require energy. As energy is exerted on the solid perssure or electric or thermal or other type, the solid will obsorb the energy and change state. The solid thereby will in turn and at a ratio, increase the thermal energy it consumes.
Does a liquid gain energy or lose energy as it changes from liquid to gas?
They gain energy. For a solid to become a liquid, energy has to be added so that the molecules can break their bond and move freely past each other. Liquids have a higher kinetic energy than a solid.
Which changes of state are characterized by having atoms that gain energy?
The changes of state characterized by having atoms that gain energy are melting and vaporization. In melting, solid atoms gain enough energy to break the bonds holding them in a fixed position, transitioning to a liquid state. In vaporization, liquid atoms gain sufficient energy to overcome intermolecular forces, transitioning to a gaseous state.
Does a substance gain energy when it freezes?
When a substance freezes, it releases energy as it changes from a higher-energy state (liquid) to a lower-energy state (solid). The energy is released as heat into the surroundings.
What physical change of a solid to a liquid at the melting point?
At the melting point, a solid absorbs heat energy and its particles gain enough energy to overcome the forces holding them in a fixed position. This results in the solid changing to a liquid state. The temperature remains constant during this phase change until all the solid has melted.
Does it gain or lose energy when a solid melts?
When a solid melts, it gains energy in the form of heat because energy is required to break the intermolecular forces holding the solid together. This energy goes into overcoming these forces, allowing the solid to transition to a liquid state.
When a substance changes from a solid to a gas it needs to what energy?
gain heat energy.
What happens to a substance during changing between a solid to a liquid?
When a substance changes from a solid to a liquid and vice versa, its density changes.
