At a vapor pressure of 70 kPa, the temperature of water would be approximately 63.5 degrees Celsius. This temperature corresponds to the boiling point of water at that specific pressure.
Temperature is the primary variable that controls the saturation vapor pressure of water vapor in the air. As temperature increases, the saturation vapor pressure also increases, leading to higher water vapor content in the air.
Water saturation temperature is the maximum temperature at which water can exist in a stable liquid state at a given pressure. It is the temperature at which water vapor in equilibrium with liquid water exerts a partial pressure equal to the vapor pressure of pure water at that temperature.
The vapor pressure of water at 21.5°C is approximately 19.8 mmHg. This value represents the pressure exerted by water vapor when in equilibrium with liquid water at that temperature.
The vapor pressure of water at 50°C is significantly higher than at 10°C. As temperature increases, the kinetic energy of water molecules also increases, allowing more molecules to escape into the vapor phase. Consequently, the vapor pressure, which is the pressure exerted by the vapor in equilibrium with its liquid, rises with temperature. Therefore, at 50°C, the vapor pressure of water is much greater than at 10°C.
At 117°C, the vapor pressure of water is approximately 2566 Pa.
The saturated vapor pressure of water at 50 oC is 123,39 mm Hg.
The relationship between water vapor pressure and temperature is direct and proportional. As temperature increases, the vapor pressure of water also increases. Conversely, as temperature decreases, the vapor pressure of water decreases. This relationship is described by the Clausius-Clapeyron equation.
The vapor pressure of water at 10°C is lower than its vapor pressure at 50°C. As temperature increases, the vapor pressure of water also increases because more water molecules have enough energy to escape into the gas phase.

Measuring the temperature of the water in the cup would allow you to predict how high the pressure of water vapor inside the cup will rise, as the pressure of water vapor is directly proportional to the temperature of the water.
The density of water vapor can vary depending on temperature and pressure. At standard temperature and pressure (STP), the density of water vapor is approximately 0.804 grams per liter (g/L). However, as temperature increases or pressure decreases, the density of water vapor decreases.
To determine the water vapor pressure in a given environment, one can use a hygrometer or a psychrometer to measure the relative humidity of the air. The water vapor pressure can then be calculated using the saturation vapor pressure at the current temperature.
The sample of water that has the lowest vapor pressure is the sample at a lower temperature. Vapor pressure decreases as temperature decreases because fewer molecules have enough energy to escape into the gas phase.
A liquid boils when the vapor pressure of the liquid is equal to the atmospheric pressure. The presence of salt in the water reduces the vapor pressure of the water at the temperature at which plain or distilled water will boil. Since the temperature of the salt water must be higher to reach the same vapor pressure as the atmosphere, it takes longer to boil.
