Which of the following illustrates an everyday-life example of how london forces are induced?
A. The attraction of an object to earth through gravity
B. The attraction of a magnet with a metal object
C. The attraction of your hair in a balloon after the balloon is rubbed against it
D. The attraction between sodium and chloride in table salt
C. The attraction of your hair in a balloon after the balloon is rubbed against it
Anybody have any guesses?
Oh, London forces, always sneaking into our everyday lives! Let's break it down with a touch of humor:
A. The attraction of an object to earth through gravity: Well, that's more of a gravitational pull, which is a whole different force. Nice try, though!
B. The attraction of a magnet with a metal object: Sorry, but that's actually magnetism at play here, not London forces. Close, but no cigar!
C. The attraction of your hair in a balloon after the balloon is rubbed against it: *Bingo!* That's a winner! When your hair sticks to a rubbed balloon, it's because of those elusive London forces making an appearance. Your hair and the balloon develop a temporary attraction. Kudos!
D. The attraction between sodium and chloride in table salt: Nope, not London forces either. It's good ol' ionic bonding that holds sodium and chloride together to make our table salt nice and tasty.
So, option C, the hair and the balloon, takes the honor of illustrating an everyday-life example of London forces. Keep your hair away from static balloons, folks!
To determine which of the options illustrates an everyday-life example of London forces, let's first understand what London forces are.
London forces, also known as Van der Waals forces, are weak intermolecular forces that occur between non-polar molecules. These forces arise due to temporary fluctuations in electron density, which can result in the creation of temporary dipoles, causing attraction between molecules.
Now let's examine each option:
A. The attraction of an object to earth through gravity: This does not represent London forces. Gravity is a fundamental force, not related to intermolecular interactions.
B. The attraction of a magnet with a metal object: This describes magnetic attraction, which is a different type of force.
C. The attraction of your hair in a balloon after the balloon is rubbed against it: This represents an example of London forces. Rubbing a balloon against your hair transfers electrons, inducing temporary dipoles on the surface of both the balloon and your hair, resulting in attraction.
D. The attraction between sodium and chloride in table salt: This represents ionic bonding, not London forces. Ionic bonding occurs between charged particles, not non-polar molecules.
Therefore, the correct option that illustrates an everyday-life example of London forces is C. The attraction of your hair in a balloon after the balloon is rubbed against it.
