Boiling point 58.78°C Melting point 7.2°C
Bromine, as many other materials gets a higher melting point when pressure is low [less energy is needed to set molecules free] and lower melting point when pressure is high [more energy needed].
Bromine (Br) Melting point: 265.8 K, -7.2 °C, 19 °F Boiling point: 332.0 K, 58.8 °C, 137.8 °F
Generally this question is asked in reference to water (which is ~100 degrees Celsius) It should be pointed out that the fact that water boils at 100 degrees Celsius and freezes at 0 degrees Celsius at one atmosphere pressure (760 mm Hg) is not a fluke. It was purposely scaled to to water. In general the boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure acting on the liquid. On Earth in the open air the boiling point of a liquid depends on atmospheric pressure. As a consequence the boiling point becomes lower as the external pressure is reduced - as when you go to the peak of a mountain.
Something boils when its vapor pressure equals the atmospheric (barometric) pressure above it. When the two are equal, that defines the boiling point.Therefore, you can either boil something by heating the liquid, and thus raising its vapor pressure (vapor pressure goes up with temperature), or you can boil something by reducing the atmospheric pressure above it until it matches the vapor pressure.See the Related Questions links to the left for more information about how the boiling point of water changes with elevation and atmospheric pressure.
The temperature at which the vapor pressure of a liquid equals the external pressure is called the boiling point. This is when the liquid changes into vapor at a constant temperature.
At high pressure the boiling point is higher.
The temperature at which the vapor pressure of a liquid is equal to the external pressure is known as the boiling point. At this point, the liquid changes to a gas by overcoming the external pressure.
It depends what chemical or compound you are comparing the boiling point to. Ethanol has an atmospheric pressure boiling point of 78.1 °C (172.6 °F). This is slightly lower than the boiling point of water at the same pressure, much lower than the boiling point of iron, much higher than the boiling point of bromine.
boiling point is a property which depends upon the atmospheric pressure. when vapour pressure of water is equal to external is called its boiling point.. if pressure is equal to atmospheric pressure ,boiling point is 100 degree celcius.
Boiling point 58.78°C Melting point 7.2°C
boiling point of a liquid is affected greatly by the external pressure as the Increase in external pressure = increase in boiling point e.g boiling point of water is 100 degree centigrade under normal pressure i.e 760 torr and has boiling point =98 degree centigrade at Murree HILLS where pressure is less than 760 torr. hence it is approved that external pressure affects boiling point. UTILITY IN INDUSTRY'' BY INCREASING THE EXTERNAL PRESSURE BOILING POINT INCREASES.SO BEFORE B.P OF ANY LIQUID it has much heat in itself which helps in cooking food earlier As in the case of pressure cooker. This property also plays a role in the VACUUM DISTILLATION for such liquids which decompose at lower temperature
As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point. A liquid boils when its vapor pressure equals atmospheric pressure.
Boiling point
Bromine, as many other materials gets a higher melting point when pressure is low [less energy is needed to set molecules free] and lower melting point when pressure is high [more energy needed].
The boiling point of a substance is the temperature at which its vapor pressure equals the atmospheric pressure, causing it to change from a liquid to a gas. The boiling point varies depending on the substance and the external pressure.
Higher altitude decreases the boiling point of water. Boiling point is defined as the point at which the vapour pressure of the substance above the liquid is equal to the external atmospheric pressure. Since the external atmospheric pressure is lower at higher altitudes, a lower vapour pressure of water is required for water to boil and therefore a lower temperature is required to achieve the desired vapour pressure.
