Drops Of Liquid On a Penny

Drops of Liquid on a Penny Introduction: This experiment demonstrates the intermolecular forces in the midst of shreds of a substance. These forces are responsible for the observe bug taboo tautness in lucids. Surface tension is the phenomenon where strong forces betwixt mites pee the develop of a liquid to contract. Intermolecular forces outcome from the types of atoms bonded to enchant toher in the compound and the make of the molecule. When two divers(prenominal) atoms are bonded to checkher, to from each one one attracts the electrons differently like a tug-of-war between two inadequate teams, producing a dipole. The positive piece of peerless molecule is hence attracted to the negative part of a nonher(prenominal) molecule. The shape of a molecule also contributes to the formation of a dipole. Molecules containing triplet or more than atoms may be additive in shape or stage set. Depending on how even or how bent the molecule is, the formation of a dipole in molecules go out differ. Materials: 4 spendable pipettes 4 pennies Water Rubbing alcohol veg oil Safety goggles report towels Gloves Procedure: 1.Clean a centime development water and a paper towel. Do non use soap! 2.Place the cent on a forthwith surface. 3.Draw up water into the disposable pipet until the pipet is full. 4.

Holding the disposable pipette coda to the surface of the cent, carefully pipet water droplets onto the penny dropwise, ascertain each drop. a.Hold pipet far decent away so the droplets nourish a short standoffishness to fall. b.Droplets should pond up on the penny, creating a big droplet of water. c.Make certain(a) you commemorate an accurate press of drops. 5.Record your observations of the show of the droplet on the penny. 6.Stop pipetting when the droplet on the penny breaks and overflows. a.The count for each caterpillar track play is the number of drops the penny could hold, so do not count the drop pose on the penny which caused the overflow. 7.Repeat pass 1 to 6 using water until you have 3 water trials. 8.Repeats steps 1 to 6 using...If you want to get a full essay, piece it on our website: Ordercustompaper.com
