What determines the boiling point of water? Why does water have a higher boiling point compared to ethanol? Why does HF have a boiling point of 19 degrees C and H2O has a boiling point of 100 degrees C? Explain the role of the stir-bar normally added to a liquid that...
This paper presents the results of measurement and calculation within an upgraded Zuber model of critical heat flux (CHF) during nucleate boiling in thin horizontal layers of liquid. The layer height was increased in regimes of developed nucleate boiling. The two-phase layer was foam with vapor c...

BOILING POINT BOILING POINT This is the temperature at which a substance evaporates as quickly as it can (liquid to gas) Different substances have different boiling points E.g. water boils at 100 C; ethanol boils at 78 C BOILING POINTS BOILING POINTS So there is a fixed temperature where a...
Calculate ΔHv of ethanol (in kJ/mol) if its vapor pressures at 35^oC and 77^oC are 115 mmHg and 760 mmHg. Find pressure of gas under 546 degrees C, that has pressure 200 mmHg under 273 degrees C. The vapor pressures of a liquid were measured at 290 and 320 K to...
