What has the greatest molecular motion?

They are in constant motion and also different from molecules such as liquid molecules have more freedom of movement compared to solid molecules. At the same time they show less movement compared to gaseous molecules. In other words, we can say that gaseous molecules have the greatest degree of motion.

Whats it called when a gas turns into a liquid?

At a certain temperature, the particles in a liquid have enough energy to become a gas. The process of a liquid becoming a gas is called boiling (or vapourization), while the process of a gas becoming a liquid is called condensation.

Is Solid hard to deform?

Solids: The strong bonds between molecules make solids rigid and very difficult to deform. Liquids: The relatively weak bonds between molecules allow liquids to be deformed without effort. Liquids have a fixed volume, but their shape is determined by the shape of the container holding them.

What happens when a solid is deformed?

The shape of an object is the geometrical description of the part of the space occupied by the object, as determined by its external boundaries. A change in shape due to the application of force is known as deformation. Even small forces are known to cause some deformation.

What substance is solid but can flow?

Granular materials are solids that can flow and behave like liquids. Examples of granular materials include sand, coffee, nuts, even corn flakes. Scientists consider things like icebergs or asteroids to be large granular materials, due to how they behave.

How does fluid deform compared to solid?

Because a fluid cannot resist deformation force, it moves, or flows under the action of the force. Its shape will change continuously as long as the force is applied. A solid can resist a deformation force while at rest. While a force may cause some displacement, the solid does not move indefinitely.

Can a solid be fluid?

Liquids and gases are considered to be fluids because they yield to shearing forces, whereas solids resist them. A rock is an example of a solid. This rock retains its shape because of the forces holding its atoms together. (b) Atoms in a liquid are also in close contact but can slide over one another.

When comparing solids to fluids the following is true?

When comparing solids to fluids, the following is true: – for elastic solids, the stress must be normal. For Newtonian fluids, the stress must be shear. – for elastic solids, the stress must be shear.

Why is there no slip condition?

In fluid dynamics, the no-slip condition for viscous fluids assumes that at a solid boundary, the fluid will have zero velocity relative to the boundary. The fluid velocity at all fluid–solid boundaries is equal to that of the solid boundary.

Is the no slip condition always true?

The no-slip condition does not always hold in reality. For example, at very low pressure such as at high altitude, even when the continuum approximation still holds there may be so few molecules near the surface that they “bounce along” down the surface.

Does the no slip condition apply to all matter?

No-slip condition is believed to be valid as far as the characteristic scale of the flow is much greater than the mean length of the path of the fluid molecular between collisions. The wall material does not matter as far as it is rigid.

Does the no slip condition apply to gases?

Specifically, adhesion and cohesion are touched upon as the governing principles for the no-slip phenomenon (though the site lacks the citation). …

How is slip length calculated?

In such techniques, the velocity profile of the liquid can be measured with high accuracy, and the slip length can be extracted from the equation [24] b=vs/∂vs/∂z, where vs and ∂vs/∂z are the velocity and the shear rate close to the surface.

How do you measure a slip length?

Slip lengths (full and half slips) are measured from the waist down – nightgowns and sleepshirts are measured from the shoulder down. Bra size is NOT the same thing as bust size. Generally, you can convert by adding bra band size (i.e., 34, 36, etc.) to cup size in inches (A=1″, B=2″, C=3″, D=4″, DD=5″).

What length slip should I wear?

Ideally, the undergarment’s hem should end two to three inches above the bottom of the skirt. “When you sit down or when you take a stride, if your slip is only an inch or half an inch shorter than your garment, you’re really risking that it’s going to peek out,” she says.

What is perfect size for a woman?

The specific proportions of 36–24–36 inches (90-60-90 centimeters) have frequently been given as the “ideal”, or “hourglass” proportions for women since at least the 1960s (these measurements are, for example, the title of a hit instrumental by The Shadows).

How do I choose a brief size?

Take measurements to choose the right size of underwear

1. Your waist measurement : measure horizontally at the thinnest point of the waist, below the ribs. The area is just above or below the belly button.
2. Your hip measurement : measure horizontally at the widest point of the pelvis, at the level of the buttocks.

What is the perfect waist size for a girl?

35 inches

Is size 42 large or XL?
