I hope this helps!
Nuggie is 100% correct, i just took it!
1) The correct answer is "boiling point, surface tension, vapor pressure". But let me ask you this, why did the vapor pressure go to therapy? Because it had a lot of boiling points it needed to vent!
2) The substance in which the electrostatic forces between molecules are the strongest is... *drumroll*... glycerin! Those molecules are pretty clingy, just like my ex!
3) The best way to describe the vapor point of a substance is the temperature at which additional heat energy causes the substance to change from a liquid to a gas. It's like when your coffee reaches that point where it decides it's had enough of being a liquid and just wants to be a gas instead.
4) To compare the electrostatic forces between molecules of different substances, you should heat each substance in liquid form to its boiling point and then measure the temperature. Just make sure you don't accidentally create a volcano in the lab!
5) Ah, vapor pressure, the pressure that makes a liquid say, "I'm done being contained, I just want to be in the air!" A liquid boils when the vapor pressure equals the atmospheric pressure. It's like when you reach that point with your homework where you say, "I'm done with this pressure, I'm just gonna go watch some TV instead!"
1) To determine which list includes only bulk properties of matter, we need to understand what bulk properties are. Bulk properties are properties that depend on the amount of substance present, such as boiling point, density, and vapor pressure.
Looking at the options provided, we can eliminate "strength of electrical forces" as it is not a bulk property but a molecular property.
Next, we see that "vapor pressure" is common to all three options, so it should be included in the correct answer.
Finally, we need to determine whether "kinetic energy" or "surface tension" should be included. Kinetic energy is not solely a bulk property but a property that depends on temperature, which is related to the average kinetic energy of molecules. Surface tension, on the other hand, is a property that depends on intermolecular forces and is therefore not solely a bulk property.
Therefore, the correct answer is: boiling point, vapor pressure.
2) To determine in which substance the electrostatic forces between molecules are the strongest, we need to compare their boiling points. The boiling point of a substance is an indicator of the strength of the intermolecular forces between its molecules. Generally, substances with stronger intermolecular forces will have higher boiling points.
In the table provided, we can see that glycerin has the highest boiling point at 290 ºC, while turpentine has the lowest boiling point at 160 ºC. This indicates that the electrostatic forces between molecules are the strongest in glycerin, making it the correct answer.
3) The vapor point of a substance refers to the temperature at which it changes from a liquid to a gas. To determine the best description of the vapor point, we need to understand the concept of phase changes.
The correct answer is: the temperature at which additional heat energy causes the substance to change from a liquid to a gas. When a substance reaches its vapor point, additional heat energy will cause the substance to undergo a phase change from a liquid to a gas. Therefore, this option best describes the vapor point.
4) To obtain the best data for comparing the electrostatic forces between the molecules of different substances, we need to consider how these forces change during a phase change.
The correct answer is: Heat each substance in liquid form to its boiling point. Measure the temperature of each substance. Heating each substance in liquid form to its boiling point ensures that the intermolecular forces are overcome, allowing the molecules to transition to a gaseous state. By measuring the temperature at which this occurs, we can compare the boiling points for each substance, which reflect the strength of the intermolecular forces.
5) The statement that correctly describes how vapor pressure is related to an observable phase change is: A liquid boils when the vapor pressure equals the atmospheric pressure.
Vapor pressure is defined as the pressure exerted by the vapor of a substance when it is in equilibrium with its liquid phase. When the vapor pressure of a liquid reaches the same value as the atmospheric pressure, the liquid will start to boil and undergo a phase change from a liquid to a gas. This is observable as the liquid starts to produce visible vapor bubbles. Therefore, the correct answer is that a liquid boils when the vapor pressure equals the atmospheric pressure.

Is the only one that describes the stuff itself, not what is happening with it.
No, I am not going to do your homework for you.
