What are the reference points in thermometer with Celsius scale?
kupik [55]
The most likely answer is the boiling point and freezing point of water.  The Celsius scale starts at the freezing point of water (0°C) and than scaled so that 100°C fell on the boiling point of water.

I hope this helps.  Let me know if anything is unclear.

Tpy6a [65]

Answer: 0.050M urea, 0.10M glucose, 0.2M sucrose, pure water

Explanation:

Vapor pressure refers to the ease with which a liquid substance is transformed into vapour. High vapour density implies that the liquid is easily transformed into gas. Pure water is expected to have the lowest vapour density since it is held by strong intermolecular forces in the liquid state. Urea is an organic liquid held by weak Van der Waals forces hence its extremely high vapor pressure.
