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.

Steam at a temperature of 113.0°C with a mass of 24.00 grams is cooled until it reaches a final temperature of 34.0°C. Use the provided data and the heating curve to calculate the amount of energy (in kJ) is required to complete this process. If the process is exothermic be sure to include the appropriate sign. Hint: Condensation is exothermic. How does that affect AH? 130 A Gas 100 IGas - Liquid ! Liquid Liquid- ! Solid Solid erature H20 (°C)

Capillary action is the process of water moving up plants, against gravity. Two different properties of liquids work together to allow this process. Please list and define one of these properties. B IU
