At an external pressure of 23.7 torr, the boiling point of water is significantly lower than its standard boiling point of 100°C (212°F) at 1 atm (760 torr). When the pressure decreases, the boiling point also decreases, and at 23.7 torr, water boils at approximately 64°C (147°F). This phenomenon occurs because lower pressure allows water molecules to escape into the gas phase more easily.
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 is the phenomenon in which saturated vapour pressure becomes equal to the external pressure. Hence as we increase the external pressure then the boiling point has to increase so as to attain that pressure
atmospheric pressure is lower and the boiling point is less
No, acidity does not directly affect the boiling point of a substance. The boiling point is mainly determined by the intermolecular forces within a substance and the external pressure exerted on it. Acidity may affect the chemical properties of a substance, but it does not have a direct impact on its boiling point.
Boiling is dependent on pressure because the pressure affects the boiling point of a substance. When the pressure is higher, the boiling point of a substance is also higher, and when the pressure is lower, the boiling point is lower. This is because pressure affects the vapor pressure of the substance, which needs to equal the atmospheric pressure for boiling to occur.
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.
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.
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.
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
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.
Boiling is the phenomenon in which saturated vapour pressure becomes equal to the external pressure. Hence as we increase the external pressure then the boiling point has to increase so as to attain that pressure
For water it is 100 degrees celsius, however it is different for other liquids ------------------------- Generally, boiling point is the temperature at which the liquid's vapour pressure is equal to the external atmospheric pressure.
