(1) In which liquid are the intermolecular attractive forces the weakest ? (2) Which liquid would be expected to have the highest vapor pressure at 31.8 °C

Air conditioners dry the air while they cool the air. Suppose an air conditioner is used to cool a room that is 6.88 m x 11.22 m × 2.26 m when the outside temperature is 37 °C. At this temperature, the vapor pressure of water is 47.1 torr. The partial pressure of water in the air is 84.5% of the vapor pressure of water. How much water, in grams, is removed from the air each time the air from the room is cycled through the air conditioner? mass of H,O:

The vapor pressure of liquid methanol, CH3OH, is 40.0 mm Hg at 278 K. A sample of CH3OH is placed in a closed, evacuated container of constant volume at a temperature of 440 K. It is found that all of the CH,OH is in the vapor phase and that the pressure is 74.0 mm Hg. If the temperature in the container is reduced to 278 K, which of the following statements are correct? Choose all that apply.: O Liquid methanol will be present. O Only methanol vapor will be present. O The pressure in the container will be 46.8 mm Hg. O No condensation will occur. O Some of the vapor initially present will condense. Subnit Answer Retry Entire Group 8 more group attempts remaining

Which of the following properties does NOT impact the vapor pressure of a particular liquid in a closed container? Amount of hydrogen bonding in the liquid The surface tension of the liquid The temperature of the liquid The volume of liquid
