Absolutely.
The most obvious examples are vaporization of a liquid when the pressure is lowered.
For example, if you release the fuel in a disposable lighter, the liquid butane becomes a gas when it reaches the lower pressure of the atmosphere.
You can demonstrate this with water by putting it in a syringe, closing the end, and rapidly pulling out the plunger. The water will actually bubble and boil at room temperature.

How does pressure affect phase change?
Pressure affects phase change by altering the equilibrium between the different phases of a substance. Increasing pressure can cause a substance to transition to a more compact phase, such as from gas to liquid or from liquid to solid. Decreasing pressure can have the opposite effect, causing a substance to transition to a less compact phase.
How do you change the state of matter?
The state of matter can be changed by altering the temperature or pressure of a substance. For example, increasing the temperature of a solid can cause it to melt and change into a liquid, while lowering the temperature of a gas can cause it to condense into a liquid. Similarly, changing the pressure can also affect the state of matter.
What is the driving force of phase change?
The driving force of a phase change is a change in the energy state of the substance. This can be caused by a change in temperature or pressure, which alters the balance of forces between the particles in the substance, leading to a transition to a different phase.
What is the phase change from solid to gas?
Sublimation is the phase change from solid to gas, where a substance transitions directly from a solid state to a gas state without passing through the liquid state. This process typically occurs under specific temperature and pressure conditions, where the solid's vapor pressure exceeds the ambient pressure.
What happens when freon is heated?
When freon is heated, it undergoes a phase change from a liquid to a gas. This change in state allows it to absorb heat from the surrounding environment, making it an effective refrigerant. Heating freon too much can cause it to decompose into potentially harmful substances.
How does particle change from phase to phase?
Temperature and/or pressure cause the bonds holding particles together to weaken.
What phase of matter is most affected by a change in pressure?
The phase of matter most affected by a change in pressure is the gaseous phase. An increase in pressure tends to make gas molecules come closer together, possibly leading to a phase change to a liquid or solid. Conversely, a decrease in pressure can cause gases to expand and possibly become less dense.
How does pressure affect phase change?
Pressure affects phase change by altering the equilibrium between the different phases of a substance. Increasing pressure can cause a substance to transition to a more compact phase, such as from gas to liquid or from liquid to solid. Decreasing pressure can have the opposite effect, causing a substance to transition to a less compact phase.
Two factors that are responsible for a phase change?
Temperature and pressure are two factors that can cause a phase change in a substance. A substance will change from one phase to another when its temperature or pressure surpass a certain threshold, known as the melting point, boiling point, or sublimation point.
How do you get a change of phase?
Change of phase is caused 99% of the time by a change in temperature or pressure.
Why does phase change occur in materials?
Changing the temperature or pressure of a material we can change the phase.
What determines the phase in which water exists by?
The phase of water (solid, liquid, gas) is determined by its temperature and pressure. At normal atmospheric pressure, water is a liquid at temperatures between 0°C and 100°C. Changes in temperature and pressure can cause water to change phases.
How does altitude affect phase change?
The change in pressure is highly affected by altitude.
How do you change the state of matter?
The state of matter can be changed by altering the temperature or pressure of a substance. For example, increasing the temperature of a solid can cause it to melt and change into a liquid, while lowering the temperature of a gas can cause it to condense into a liquid. Similarly, changing the pressure can also affect the state of matter.
Does the temperature change while a phase chage is occurring?
No, the temperature does not change during a phase change. It remains constant until all the substance has undergone the phase change.
A change of phase takes place at a constant?
A change of phase takes place at a constant temperature and pressure. During a change of phase, the substance absorbs or releases latent heat without a change in temperature.
Why is it not always easy to cause phase changes changing a liquid to a gas f?
In order to change a liquid to a gas, it has to reach its boiling point, which depends on the pressure.
