Part B Suppose that 0.48 g of water at 25° C condenses on the surface of a 55-g block of aluminum that is initially at 25°C. If the heat released during condensation goes only toward heating the metal, what is the final temperature (in degrees Celsius) of the metal block? (The specific heat capacity of aluminum, Cs,A1, is 0.903 J/(g. °C).) Express your answer in degrees Celsius to two significant figures. IVO ΑΣφ ? T = 22 C Submit Previous...

Part A The vapor pressure of a certain sample has been measured at two different temperatures and the results are P1 = 140 kPa at T1 = 240 K and P2 = 840 kPa at T2 = 270 K. Determine the molar vaporization enthalpy, AHvan, from these results. 32.2 kJ mol-1 10.9 kJ mol-1 O 27.3 kJ mol-1 29.8 kJ mol-1 22.1 kJ mol-1

Review Constants Pe Consider the following two substances and their vapor pressures at 298 K All liquids evaporate to a certain extent. The pressure exerted by the gas phase in equilibrium with the liquid is called vapor pressure. Prap. The vapor pressure of a particular substance is determined by the strength of the intermolecular forces. But for any given substance, the vapor pressure only changes with temperature. The Clausius-Clapeyron equation expresses the relationship between vapor pressure and temperature: Substance Vapor...

II Revi Part A The vapor pressure of a substance describes how readily molecules at the surface of the substance enter the gaseous phase. At the boiling point of a liquid, the liquid's vapor pressure is equal to or greater than the atmospheric pressure exerted on the surface of the liquid. Since the atmospheric pressure at higher elevations is lower than at sea level, the boiling point of water decreases as the elevation increases. The atmospheric pressure at sea level...
