the temperature of steam rising from pure water boiling understand atmosphere pressure is ?
Please explain why it is like that
Steam has to be 100C or greater. When generated from boiling water, it cannot be greater than 100C unless the steam itself is heated after generation.
"the temperature of steam rising from pure water boiling understand atmosphere pressure is ?"
It's amazing bobpursley could even make sense of the question! Isaac, in the future, you should include all the words in the question. When you try to type fewer words, you produce something less than intelligible.
The temperature at which water boils depends on the atmospheric pressure. At sea level, the standard atmospheric pressure is about 1 atmosphere (atm). At this pressure, water boils at 100 degrees Celsius or 212 degrees Fahrenheit. However, as the atmospheric pressure changes, so does the boiling point of water.
To explain why, we need to understand the concept of vapor pressure. Vapor pressure is the pressure exerted by a vapor in equilibrium with its liquid at a given temperature. When the vapor pressure of a liquid equals the atmospheric pressure, boiling occurs.
As the atmospheric pressure decreases, like at high altitudes where the air pressure is lower, the vapor pressure required for boiling to occur also decreases. Therefore, it takes less energy for the vapor pressure of the water to reach the lower atmospheric pressure, resulting in a lower boiling point. In such cases, water boils at temperatures lower than 100 degrees Celsius.
On the other hand, if the atmospheric pressure increases, it takes more energy for the vapor pressure of the water to reach the higher atmospheric pressure, resulting in a higher boiling point. For example, in a pressure cooker where the pressure is higher than atmospheric pressure, the boiling point of water would be higher than 100 degrees Celsius.
In summary, the temperature of steam rising from pure water boiling depends on the atmospheric pressure. Higher atmospheric pressure results in a higher boiling point, while lower atmospheric pressure results in a lower boiling point.
