Mr Aboki: OYO!!!!dafuq is this clown ![]() |
Toluwani2: Unemployed Graduates with DISABILITY: what is the way forward?LEARN A TRADE THAT BEFFITS UR DISABILITY ![]() |
Nice innovation |
Polio: STFU ... Swine!lol.. I'm not about to get banned because of u.. So Swerve |
2sureguy1: United we stand...!.....buh i sensed we ar stil gonna b defeated & dance Skelewu @ Old trafford 2day cuz it's nt a easy dance....IJN.....jez click like 2 say AMEN. |
Polio: Dead Manchester United wont have it easy against Real Sociedad tonight!oga stop making a noise ![]() |
GGMU til i die aunty mukina2 HBD in arrears ![]() |

And this is on FP? E.T.T ![]() |
tsleazy: hey....MiKe TySoN is backwho is mike tyson |

WTF is going on |
Rehnoy: And now, this is what I call being a gentle man. We're cool brov.thank u sir |
Rehnoy: shut up my frnd. Mr belowsabi. I was only trying to tell you that you were making the thread unnecessarily long. Something that requires just two lines answer, you're here pasting a whole research. Next time, drop the link let whoever wanna read go and read there. Shikina.my good sir.. Pls ignore titanium.. He is fond of derailing.. Pls lets not derail the thread.. Lets do what the thread is meant 4.. Thanks ![]() |
Rehnoy: Dunno hw to post a link, but that's your link. Check it, then tell me its not same.ok ok.. U got me.. But i used yahoo just so that i could explain further to u guys.. I promise it wouldn't happen again.. We cool? ![]() |
FILEBE: Andbros u get mouth jawe.. 9JA 4 LIFE |
These boys are trying sha.. ![]() |
speedyboi: Same thing!oops.. Sorry sir ![]() i will stop it if it's unacceptable ![]() |
Rehnoy: You want me to prove you wrong?go ahead sir ![]() |
Doc_miss.. Na story make u leave science thread abi.. ![]() |
odizeey: sylva na swagless boy,na d ceo go like amodizeey.. If ah catch u ehn ![]() |
Mehlena: lol sure na no prbz..wetin you want? Shey make i give you Betty? Or Alex?na betty sure pass woh |
Rehnoy: I almost thought so.be rest assured sir.. I didn't use google.. Rather i used a textbook ![]() |
speedyboi: Obviouslyit is without google sir.. I didn't use google |
Rehnoy: Sorry sir, but this looks CoPIED & PASTED.lol.. No sir its not... Actually i used a textbook.. ![]() |
Rehnoy: What has here turned into?it is still what it has always been |
speedyboi: I would've spoilt this question if I was asked some years back! But make i still try shaclose adaobi123: Okay. Its something to do with the intermolecular forces in between each water molecule. I think they more forces on h2o than in methane and n2 etc.a bit close lemme explain extensively Water molecules are polar due to the polarity of covalent bonds between oxygen and hydrogen atoms, and the bent shape of molecules. Hydrogen and oxygen atoms have different electronegativities (H = 2.2; O = 3.5). The difference between their electronegativities (1.3) creates a strong displacement of charge making oxygen atoms strongly negative, leaving hydrogen atoms strongly positive. The position of hydrogen atoms on one side of thewater moleculemakes that side strongly positive, while the oxygen side is strongly negative. Polar molecules attract each other electrostatically. In case of water, that attraction is strong enough to be called "hydrogen bonding" reserved for polar molecules that contain hydrogen bonded to a small, highly electronegative atom like F, O, or N. Hydrogen bonding holds water molecules strongly to one another preventing their evaporation. This in turn lowers water's vapor pressure (less molecules evaporate), and raises water's boiling point (more energy is required to separate molecules from each other). By contrast, nitrogen (N2) and methane(CH4) molecules are nonpolar in nature, and attract one another primarily with weak London forces due to fluctuating dipoles caused by momentary fluctuations of electron clouds around atoms. In those substances, molecules are not attracted to each other strongly, so they can evaporate easily. This in turn gives those substances very high vapor pressure and very low boiling points. |
speedyboi: My own question!earth fault is a phenomena that occurs when electricity travels outside an intended path and tries to get to the ground by the shortest route. |
Mikebis: Can any1 dffrentiate btw law of gravity and aerodynamicswell to the best of my knowledge, gravity deals with air resistance while Aerodynamics deals with the way air moves around things. |
adaobi123: I hate physics. Oghos1: *mj's voice 'yu r nt alooooone'dat makes it 3 of us |
adaobi123: I hate physics.welcome aunty ada.. Just tell us what u like.. This z a general science thread ![]() here's a chemistry question water has a considerably higher boiling point and lower vapor pressure than other molecules of similar or larger molar mass. For example, dinitrogen (N2), methane (CH4), etc. all have lower boiling points and higher vapor pressures than water at the same temperature. How might this be explained? |
