In class, we did a lab to determine the boiling point of rubbing alcohol. We used a thiele tube filled with water and place a test tube attached to a thermometer w/rubber band in it. However, we never saw any signs of boiling. We conducted several trials, the temperature went all the...
The boiling point of alcohol is 78.3 degrees Celcius at 760 mm atm pressure. Would the boiling point be higher or lower than 78.3 degrees Celcius at higher altitudes? Why? What characteristics would a more volatile liquid have compared to a less...
A.waterB.alcoholC.nitrogenD.oxygen【小题3】Mixing alcohol and water is often used to wash windscreens of cars during the wintertime because ___. A.it is easier for alcohol to change into gasB.alcohol is not easily separated from waterC.alcohol freezes at lower temperature than waterD.the...
Temperature, atmospheric pressure, and the vapour pressure of the liquid are the three main things on which the Boiling Point of a particular liquid is based. The vapour tends to increase with the increase in temperature, which affects the Boiling Point of the liquid accordingly. Atmospheric press...
Why does a sample of boiling water remain at the same temperature until all the water has been boiled? Explain how the addition of a solute affects the boiling point of a solvent? Why does water have a higher boiling point than alcohol even though water is a smaller molecule?
Definition: Boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure, and this pressure in general is considered to be 1 atm (also known as standard pressure). Physically, the boiling point is the temperature in which the molecules presents in...
