Vapor pressure of liquid silver at 2.29x10³ K:
The Clausius-Clapeyron equation can be used to calculate the vapor pressure of liquid silver at a temperature of 2.29x10³ K.
Molar Heat Vaporization of Liquid Silver: The molar heat vaporization of liquid silver is the amount of energy required to convert one mole of liquid silver into vapor at constant temperature and pressure. In this case, it is 275 kJ/mol.
Calculating Vapor Pressure: To calculate the vapor pressure of liquid silver at a temperature of 2.29x10³ K, we can use the Clausius-Clapeyron equation. The equation is ln(P₂/P₁) = (ΔH_vap/R) * (1/T₁ - 1/T₂), where P₁ is the vapor pressure at temperature T₁, P₂ is the vapor pressure at temperature T₂, ΔH_vap is the molar heat vaporization, and R is the ideal gas constant.
Rearranging the equation, we get P₂ = P₁ * e^((ΔH_vap/R) * (1/T₁ - 1/T₂)). By plugging in the known values, such as the molar heat vaporization of liquid silver and temperatures, we can calculate the vapor pressure of liquid silver at 2.29x10³ K.
Understanding how to calculate vapor pressure is essential in chemistry and physics. It shows the relationship between temperature and the tendency of a substance to evaporate into a gas. By utilizing equations like the Clausius-Clapeyron equation, scientists and researchers can make predictions and understand the behavior of substances at different temperatures.
