Why do water drops bead on a freshly waxed surface?

Why does water bead on wax?

Water molecules are attracted in every direction by other water molecules and are more attract- ed to each other than they are to the wax paper. … Water’s attraction to itself and its strong surface tension causes water to bead up instead of spreading out on the wax paper.

Why do water drops bead on a freshly waxed surface quizlet?

Why do water drops bead on a freshly waxed surface? The strong cohesive forces between water molecules attract each other and the result is a sphere, which is squashed down into a bead by the force of gravity. … It keeps water molecules away from the surface.

Why does water form spherical drops when on a waxed surface?

Surface tension is responsible for the shape of liquid droplets. Although easily deformed, droplets of water tend to be pulled into a spherical shape by the cohesive forces of the surface layer. In the absence of other forces, including gravity, drops of virtually all liquids would be approximately spherical.

Why does water bead up more on a car that is waxed than isn t?

Wax is composed of long hydrocarbon molecules that do not interact well with water. … A freshly waxed car has low adhesive forces with water, so water beads up on the surface, as a consequence of its cohesion and surface tension.

What happens when pressure is applied to ice crystals?

What happens to ice when great pressure is applied to it? The increase in pressure causes temperature to rise, which makes the ice crystal to melt. … Combination of different types of molecules into one mixture causes the mixture temperature to increases or decreases.

What Causes Water beads on surface like glass?

What causes water to form beads on a smooth surface? The hydrogen ends of the molecule are positive and the oxygen end is negative. This causes water molecules to attract each other and other polar molecules. This attraction between water molecules can be seen on a smooth surface such as glass, where water beads up.

Which liquid has the weakest surface tension?

Hexane, C6H14, has the lowest surface tension of all the liquids given here. Hexane is a non-polar molecule, the only intermolecular forces acting between hexane molecules in the liquid will be the weakest of all the intermolecular forces, London forces (also known as dispersion forces).

When the wax paper was tilted What did the big drop of water do?

Waxed paper pushes water away and does not absorb it. The surface tension of the water pulls it into a little round blob; these blobs, or drops, can slide around waxed paper because the paper does not absorb it.

What did you notice with the droplets of water on the foil when you shook it?

“What do you notice about the drop of water you put on the aluminum foil?” It spreads out. … “On the aluminum foil, the water molecules spread out because they are attracted to the aluminum.”
