Stop Being a B is wrong! I just took the test and you got me a 0. The correct answers are
1. Boiling point, Surface Tension, and vapor Pressure
2. Glycerin
3. the temperature at which additional heat energy causes the substance to change from a liquid to a gas
4.Heat each substance in liquid form to its boiling point. Measure the temperature of each substance.
5. A liquid boils when the vapor pressure equals the atmospheric pressure.
I hope this helps!
