What is dependency of pressure and boiling point?

As air pressure drops over the water surface the boiling point will drop and vice versa. So a kettle of water will boil at a lower temperature at the top of a mountain than at sea level because there's lower air or atmospheric pressure at the mountain top. Pressure is proportional to boiling point


Air moves from a point at which air pressure is to a point at which air pressure is?

higher. This movement of air is driven by the pressure difference between the two points. The air flows from areas of higher pressure to areas of lower pressure in an attempt to equalize the pressure.


Freezing point is the point at which a liquid turns into a solid What effect can change the freezing point?

Changing the pressure can affect the freezing point of a substance. Generally, an increase in pressure will lower the freezing point, while a decrease in pressure will raise the freezing point. The presence of solutes or impurities in the liquid can also change the freezing point.


For any pure substance the boiling point and melting point will always remain?

The melting point and the boiling point of a substance are physical characteristics for each substance and are unchanged at the same pressure.


What is the boiling point of bromine when the external pressure is 75 kPa?

The boiling point of bromine under a pressure of 75 kPa is approximately 58°C. At this pressure, the boiling point of bromine is lower than its usual boiling point of 58.8°C at standard atmospheric pressure.
