Determining boiling point chemistry
WebDetermining Boiling Points from Structure. Order these compounds from lowest to highest boiling point: Hexane -1. Water -2. NaCl -3. Boiling point = intensive -> from chemical make up. Chemical makeup = … WebThe Boiling point of a liquid is an important physical property. A liquid boiling point is the temperature when its vapor pressure is equal to the atmospheric pressure. Normally, the boiling point is measured at one atmosphere (101 kPa or 760 mmHg or 760 torr). Like melting points, boiling points are characteristic properties of pure materials.
