What processes is most affected by pressure freezing or boiling or melting?
Boiling and freezing points of a substance are affected by pressure. An increase in pressure raises the boiling point and lowers the freezing point of a substance. Melting point is not significantly affected by pressure.
How do altitude affect freezing melting and boiling points of water?
As altitude increases, the air pressure decreases. This results in lower boiling points for water because there is less atmospheric pressure pushing down on the water. However, the freezing point of water is not significantly affected by altitude.
Is boiling the reverse of freezing?
no it is not melting is the reverse of freezing
What are the freezing melting boiling and evaporation points of water?
The melting/freezing point of water is oC.The boiling point of water is 100 oC at standard pressure.Evaporation occur at any temperature.
What is the freezing and melting point of the element hydrogen?
Freezing point: -434.5°F , -259.2°C, 14oK Melting point is obviously any temperature higher than the freezing point. The boiling point however is: -423.0°F, -252.8°C, 20oK All temperatures are at a pressure of 1 atmosphere

Melting freezing and boiling are what kind of change?
Melting, freezing, and boiling are physical changes, as they do not involve a change in the chemical composition of the substance.
Is the boiling point of something the same as the melting point?
The boiling point is the temperature at which the vapor pressure of the liquid is equal to the external pressure. It is also the condensation point. The freezing point is the temperature at which liquid and solid coexist in equilibrium. It is also the melting point.
What is the antonym of freezing?
Melting, boiling, burning, hot.
How does water change its state?
By freezing, melting or boiling.
What is the temperature of germanium as a liquid?
At a pressure of one atmosphere Germanium is a liquid between the melting temperature of 938.25 °C (that is 1720.85 °F) and the boiling temperature of 2833 °C (that is 5131 °F). This temperature range is affected by pressure and in order to have boiling and melting points for an arbitrary environmental pressure the Germanium Phase Diagram has to be consulted, providing the boiling and melting temperatures versus the environmental pressure.
What are the freezing melting boiling and evaporation points of water?
The melting/freezing point of water is oC.The boiling point of water is 100 oC at standard pressure.Evaporation occur at any temperature.
What is mean by melting and boiling point?
Melting point & boiling point means the temp that things melt & boil. Water's freezing & melting point is 32 degrees Fahrenheit or 0 degrees Celsius. The boiling point of water is 100 degrees Celsius or 212 degrees Fahrenheit. Different liquids or substances have different melting, freezing, and boiling points.
Are melting and boiling points of a substance the same?
The melting and boiling points of a substance (in this case I am assuming you are referring to a pure substance, and not a mixture), are the same. The triple point is defined by the temperature and pressure at which solid, liquid, and vapor of a substance, can coexist in equilibrium. At any pressure below the triple point, only sublimation and condensation are possible (no liquid phase is possible). Between the triple point pressure and the critical point pressure, there is a difference between the melting and boiling points, of a substance. The melting point temperature will be lower than the boiling point. At the critical point, the densities of the liquid and vapor phases, have merged, and boiling no longer occurs. At and above the critical point, you cease to get liquid and vapor, but you get what is referred to as a "supercritical fluid".
