Why does water pouring from a glass sometimes travel down the side of the glass?

Angle and speed When the angle between vertical direction and the glass wall is small, surface tension is stronger and the component of gravity perpendicular to the glass wall is small; consequently, water sticks to the outside surface of the container (or in other words, runs down the side of the container).

What happened to the different liquids after pouring them in an empty container?

That is why liquids and gases are also called fluids: because they can flow. When you pour fluid out of a container you remove particles from that container leaving space behind. One of two things can happen as a result: The container can collapse and become smaller or another fluid can rush in and fill the emptiness.

Why does water when poured into a cup always pour as a stream?

Water has a tendancy to stick to glass, so the water in your glass (or in the example above your teapot) has to detach from the glass at the lip to avoid dribbling. If you pour fast the momentum of the water will pull it free of the glass and it will pour cleanly.

Why does water stay on glass?

Water molecules are attracted to the molecules in the wall of the glass beaker. And since water molecules like to stick together, when the molecules touching the glass cling to it, other water molecules cling to the molecules touching the glass, forming the meniscus.

Why do things drip?

The simple answer is surface tension. Say you’re pouring water out of a pitcher. Surface tension is causing it to stick to the pitcher.

What does adhesion and cohesion mean?

Cohesion: Water is attracted to water. Adhesion: Water is attracted to other substances. Adhesion and cohesion are water properties that affect every water molecule on Earth and also the interaction of water molecules with molecules of other substances.

Why do liquids flow when poured down?

The forces between liquid particles are weaker than the forces between solid particles. This means that liquid particles are further apart and can move about more easily. Since the particles can move, the liquid can flow and take the shape of its container.

Why do gases and liquids flow differently?

The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape.

Why does water pour?

Water has a strong cohesive property because of the water particles’ ability to form hydrogen bonds with one another. As a result of this strong cohesive property, water droplets will stick to one another.

Why does water stick to itself?

Water has an amazing ability to adhere (stick) to itself and to other substances. In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

How do you prevent spilling when pouring?

Tilt the container containing the liquid quickly when you start pouring it. This will prevent the liquid from dripping along it’s sides. Hold a long handled spoon vertically in the centre of the empty container into which you want to pour the liquid with one hand.
