Intermolecular Forces

The term “INTERMOLECULAR forces” is used to describe the forces of attraction BETWEEN atoms, molecules, and ions when they are placed close to each other.
• When intermolecular forces are strong the atoms, molecules or ions are strongly attracted to each other, and draw closer together.
• When intermolecular forces are weak, the atoms, molecules or ions do not have a strong attraction for each other and move far apart.

London Dispersion Forces (LDFs):

LDFs exist for all substances, whether composed of polar or nonpolar molecules
LDF arise from the formation of temporary instantaneous polarities across a molecule from the circulations of electrons.

Dipole-Dipole Interactions:

Dipole-dipole forces exist between molecules that are polar-those that have a permanent dipole moment due to uneven sharing of electrons. This uneven sharing gives one side of the molecule a partial positive charge (δ+) and the other side a partially negative charge (δ-).

Hydrogen Bonds:

When a hydrogen atom is covalently bonded to nitrogen, oxygen or fluorine a very strong dipole is formed. The dipole-dipole interactions that result from these dipoles is known as hydrogen bonding.

Volleyball

Ang volleyball ay nilalaro ng dalawang koponan, kadalasan ng anim na manlalaro sa isang gilid, kung saan ginagamit ng mga manlalaro ang kanilang mga kamay upang i-bat ang bola nang pabalik-balik sa ibabaw ng mataas na net, sinusubukang ilapat ang bola sa court sa loob ng playing area ng mga kalaban bago nito magawang ibalik.

Basketball

Ang basketball ay larong nilalaro sa pagitan ng dalawang koponan ng limang manlalaro bawat isa sa isang parihabang court, kadalasan sa loob ng bahay. Ang bawat koponan ay sumusubok na makaiskor sa pamamagitan ng paghagis ng bola sa layunin ng kalaban, isang nakataas na pahalang na hoop at lambat na tinatawag na basket.

Badminton

Ang badminton ay nilalaro gamit ang magaan na raket at shuttlecock. Sa kasaysayan, ang shuttlecock (kilala rin bilang "ibon" o "birdie") ay isang maliit na cork hemisphere na may 16 na balahibo ng gansa na nakakabit at tumitimbang ng humigit-kumulang 0.17 onsa (5 gramo).
