in low pressure environments it is possible for a solid to change to a liquid
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, causing the liquid to change into a gas. It is a characteristic property of the liquid and can be influenced by factors such as pressure and impurities in the liquid.
by applying pressure
You can change the boiling point of a liquid by adjusting the pressure on the liquid. Increasing the pressure raises the boiling point, while decreasing the pressure lowers it. This is why water boils at a lower temperature at higher altitudes where the atmospheric pressure is lower.
When the vapor pressure equals atmospheric pressure at the surface of a liquid, it has reached its boiling point. This is the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on it by the surrounding atmosphere, causing the liquid to change into vapor.
The likely cause of bubbles forming in a liquid without a change in temperature is a decrease in pressure. When pressure decreases, gases dissolved in the liquid can come out of solution and form bubbles. This phenomenon is known as cavitation.
Actually boiling is a point where the vapour pressure of any liquid (example: water) becomes equal to the surrounding pressure.
The boiling point of a liquid can change with air pressure. As air pressure decreases, the boiling point of a liquid also decreases, meaning it will boil at a lower temperature. Conversely, as air pressure increases, the boiling point of the liquid increases, requiring a higher temperature to boil.
Cooling the high pressure vapor to lower its temperature and increase its density can cause it to condense and change into a high pressure liquid.
decreased heat, increased pressure
Cool it down or increase the pressure (or both)
everything with the right balance of temperature and pressure
