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.

What temperature does water boil and evaporates into steam?
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.
Why does pressured water have a raised boiling point?
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
Why the boiling point is lees than 100 on 760 mmHg pressure?
The boiling point of a liquid is the temperature at which its vapor pressure equals the external pressure. At standard atmospheric pressure (760 mmHg), water boils at 100°C. However, if the external pressure is lower than 760 mmHg, the vapor pressure of the liquid can reach the external pressure at a lower temperature, resulting in a boiling point that is less than 100°C. This phenomenon is commonly observed at high altitudes where atmospheric pressure is reduced.
What is the boiling point of isopropyl alcohol when the external pressure is increased. to standard pressure?
The boiling point of isopropyl alcohol (isopropanol) is approximately 82.6°C at standard atmospheric pressure (1 atm). When the external pressure is increased, the boiling point of isopropyl alcohol also increases. This is because a higher pressure requires the liquid to reach a higher temperature for its vapor pressure to equal the external pressure, allowing it to boil. Thus, under increased pressure conditions, isopropyl alcohol would boil at a temperature above 82.6°C.
When a liquid sample is taken from sea level to a higher elevation what happens to the external pressure on the liquid and the boiling point of the liquid?
atmospheric pressure is lower and the boiling point is less
The temperature at which the vapor pressure of a liquid is equal to the external pressure is?
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.
As external pressure such as atmospheric pressure on liquid increases its boiling 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 the what?
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.
What temperature does water boil and evaporates into steam?

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.
How does external pressure affect the boiling point of a liquid and how is this utilized in the food industry?
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
Relation between atmospheric pressure and boiling point?
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.
The temperature at which the pressure of the vapor in the liquid is equal to the external pressure acting on the surface of the liquid is a?
Boiling point
What is the boiling point of any substance?
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.
What effcet does altitude have on boiling point of water?
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.
Why does pressured water have a raised boiling point?
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
Why the boiling point is lees than 100 on 760 mmHg pressure?

However, if the external pressure is lower than 760 mmHg, the vapor pressure of the liquid can reach the external pressure at a lower temperature, resulting in a boiling point that is less than 100°C. This phenomenon is commonly observed at high altitudes where atmospheric pressure is reduced.
