If the molal boiling point constant for water (Kb) is 0.51 C/m, what would be the boiling point of this solution? A solution prepared by dissolving 0.059 moles of LiCl in 50 grams of water has a freezing point of -3.0 degre...
Answer to: What is the change in boiling point (in degrees Celsius) of a solution prepared by dissolving 30 g of aluminum chloride in 550 mL of...
A liquid's freezing point is -38 degree Celsius and its boiling point is 37 degree Celsius. What is the number of kelvin between the boiling point and the freezing point of the liquid? What is the boiling temperature of water in both Fahrenheit and C...
Depending on temperature, air can hold a fixed amount of water vapor; relative humidity is the ratio of actual vapor in the air to this fixed amount. For example, at a temperature of 68 degrees Fahrenheit (20 degrees Celsius), one cubic meter (35 cubic feet) of air can hold about 18 ...
A. 0 degrees Celsius. B. 32 degrees Fahrenheit. C. 100 degrees Celsius. D. 212 degrees Fahrenheit. 相关知识点: 试题来源: 解析 C。水的沸点是 100 摄氏度,所以答案是 C。A 选项是水的冰点;B 选项是 32 华氏度,是水的冰点对应的华氏温度;D 选项是 212 华氏度,是水的沸点对应的华氏温度。反馈...
This means that a salt dissolved in water will boil above 100 degrees Celsius and freeze below 0 degrees Celsius at normal atmospheric pressure. In addition, the vapor pressure of a solvent decreases when a non-volatile solute is dissolved. This is ...
