- In the northern United States, summer cottages are usually closed up for the winter. When doing so, the owners winterize the plumbing by putting antifreeze in the toilet tanks, for example. Will adding 525 g of HOCH2CH2OH to 3.00 kg of water ensure that the water will not freeze at 25 C?arrow_forwardA student leaving campus for spring break wants to make sure the air in her dorm room has a high water vapor pressure so that her plants are comfortable. The dorm room measures 3.25 m × 4.03 m × 3.04 m and the student places a pan containing 0.580 L of water in the room. Assume that the room is airtight, that there is no water vapor in the air when she closes the door, and that the temperature remains a constant 22 °C. The vapor pressure of water at 22 °C is 19.8 mm Hg. Calculate the pressure that the water vapor would exert if all of the liquid water evaporated. mm Hg Will all of the water in the pan evaporate?arrow_forwardIn a body of water, the surface tension caused by the attraction between water molecules is strong. Which of the following is a consequence of this property? Water is considered to be a universal solvent. When water freezes, the molecules move farther apart. Only a limited amount of solute can be dissolved in a sample of water. Objects with a higher density than water can be observed floating on water.arrow_forward
- Four liquids are described in the table below. Use the second column of the table to explain the order of their freezing points, and the third column to explain the order of their boiling points. For example, select '1' in the second column next to the liquid with the lowest freezing point. Select '2' in the second column next to the liquid with the next higher freezing point, and so on. In the third column, select '1' next to the liquid with the lowest boiling point, '2' next to the liquid with the next higher boiling point, and so on.
