Dew point is the temperature at which the air reaches saturation. Warmer air can retain more moisture than cooler air. So, ignoring other factors such as pressure, when the temperature drops to the dew point temperature, the air becomes saturated and therefore, if there is actually moisture in the air (is there a cloud?), it will start to rain or snow.

What is difference between critical temperature and boiling point?
The critical temperature is the highest temperature at which a substance can exist in a distinct liquid and gas phase, above which the substance becomes a supercritical fluid. The boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure, causing the liquid to transition into a gas phase.
When does Boiling temperature Start?
Boiling temperature starts when the liquid reaches its boiling point, which is the temperature at which its vapor pressure equals atmospheric pressure. At this point, the liquid begins to vaporize and turn into a gas.
How can one determine the relative humidity by using the temperature as a reference point?
To determine relative humidity using temperature as a reference point, you can use a psychrometric chart or an online calculator. By knowing the temperature and the dew point, you can calculate the relative humidity. The relationship between temperature and relative humidity is important in understanding the moisture content in the air.
How do water temperatures affect air pressure?
The lower the pressure then the lower the temperature that is required to make it boil. Water at the top of Mount Everest boils well below 100 degrees centigrade due to the lower atmospheric pressure.
What can be said of a boiling point of a liquid?
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, causing the liquid to change into a gas. It is a characteristic property of the liquid and can be influenced by factors such as pressure and impurities in the liquid.
What is the relationship between pressure and the boiling point of water?
The relationship between pressure and the boiling point of water is that as pressure increases, the boiling point of water also increases. This means that water will boil at a higher temperature under higher pressure. Conversely, water will boil at a lower temperature under lower pressure.
How does pressure affect the temperature at which water boils?
There is a direct relationship between the temperature at which water boils and the air pressure on it. Higher pressure, higher boiling point. Lower pressure, lower boiling point.
What is the relationship between the temperature and dew point?
Dew point is the temperature at which the water vapor in the air condenses, then evaporates. The barometric or air pressure is independent from the dew point.
What is the relationship between dew point and pressure?
The relationship between dew point and pressure is that as pressure increases, the dew point temperature also increases. This means that at higher pressures, the air can hold more water vapor before reaching saturation, resulting in a higher dew point temperature. Conversely, at lower pressures, the air can hold less water vapor before reaching saturation, leading to a lower dew point temperature.
What is the relationship between the normal boiling point and vapor pressure of a substance?
The normal boiling point of a substance is the temperature at which its vapor pressure equals the atmospheric pressure. In other words, the higher the vapor pressure of a substance, the lower its normal boiling point will be.
What information does the water freezing point pressure chart provide?
The water freezing point pressure chart provides data on the relationship between pressure and the temperature at which water freezes. It shows how the freezing point of water changes as pressure increases or decreases.
What is the relationship between pressure and boiling point according to the formula?
The relationship between pressure and boiling point is described by the formula: T K m P. This formula shows that as pressure increases, the boiling point of a substance also increases.
What is the relationship between the triple point of water and the si unit for temperature?
The triple point of water is a specific temperature and pressure at which water can exist as a solid, liquid, and gas simultaneously. The SI unit for temperature is the kelvin (K), which is defined based on the triple point of water (273.16 K). This relationship helps ensure consistency and accuracy in temperature measurement.
What is the relationship between air temperature and dew point temperature when dew occurs?
They are the same.
What is the relationship between boiling point and vapor pressure?
The relationship between boiling point and vapor pressure is that as vapor pressure increases, the boiling point decreases. This is because higher vapor pressure means that the liquid molecules are more likely to escape into the gas phase, leading to a lower boiling point.
What is the relationship between air temperature and dew point temperature at ground level if it is foggy?
They are about the same.
What is the relationship between boiling point and pressure?
The relationship between boiling point and pressure is that as pressure increases, the boiling point of a substance also increases. This is because higher pressure makes it harder for molecules to escape into the gas phase, requiring more energy to reach the boiling point. Conversely, lower pressure decreases the boiling point as it allows molecules to escape more easily.
