What is the proper way to hold a dropper?
Hold the dropper vertically with the tip pointed downward to prevent spills. Squeeze the bulb gently and release it slowly to control the flow of liquid being dispensed. Avoid touching the tip to prevent contamination.
Why the effect of gravitation is more in liquid than in solid?
Gravitational force is more effective in liquids compared to solids due to the ability of liquids to flow and conform to the shape of their containers. In solids, the molecular structure is more rigid, making it harder for gravity to have a noticeable effect. The ability of liquids to flow allows gravity to exert a stronger influence.
Why has a liquid got a medium density?
A liquid has a medium density because its particles are more closely packed together compared to a gas, but less closely packed compared to a solid. The spacing between the particles allows for the liquid to flow and take the shape of its container while still retaining a certain level of density.
What happens when you mix liquids with gas?
When you mix liquids with gas, the gas can dissolve in the liquid or form bubbles within the liquid. This can alter the properties of the liquid, such as its density and ability to flow. The gas molecules can also escape from the liquid if the conditions change.
What is the property of liquid?
Liquid is one of the three classical states of matter (the others being gas and solid). Like a gas, a liquid is able to flow and take the shape of a container. Some liquids resist compression, while others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena. The density of a liquid is usually close to that of a solid, and much higher than in a gas. Therefore, liquid and solid are both termed condensed matter. On the other hand, as liquids and gases share the ability to flow, they are both called fluids.Ctrl+a
What holds the liquid in a medicine dropper?
The liquid in a medicine dropper is held by surface tension, a property of liquids that causes them to stick together and form a sort of "skin" on the surface keeping the liquid together. Additionally, the small opening at the tip of the dropper helps regulate the flow of liquid.
If you increase density of liquid the effect on viscosity is?
Increasing the density of a liquid typically results in an increase in viscosity. This is because higher density usually means more intermolecular interactions and greater resistance to flow. In other words, the molecules are packed more tightly, leading to stronger forces between them, which makes it more difficult for the liquid to flow.
Why is the opening of a dropper very narrow?
The opening of a dropper is narrow to control the flow rate of liquid being dispensed. This helps to accurately measure and transfer small volumes of liquid, making it useful in various applications such as scientific experiments and medical procedures.
What are the special properties of liquids?
liquid cam flow easily . they have low density.
What is the proper way to hold a dropper?
Hold the dropper vertically with the tip pointed downward to prevent spills. Squeeze the bulb gently and release it slowly to control the flow of liquid being dispensed. Avoid touching the tip to prevent contamination.
Does a viscous liquid have to be dense?
No, the viscosity of a liquid refers to its resistance to flow, while density refers to the mass of a substance per unit volume. A liquid can be viscous without being dense, as viscosity and density are independent properties.
Why must you poke a hole in a can to allow the liquid to flow out faster?
Poking a hole in a can allows air to flow into the can, which helps the liquid flow out smoothly by breaking the vacuum seal. Without the hole, the liquid would flow slower due to the vacuum effect that restricts air entering the can to replace the liquid leaving.
What are limitations of velocity of flow in a pipeline?
The velocity of flow in any pipe is determined by three things. The internal pipe diameter, the mass flow rate of the liquid and the fluid density.

What happen when you hold a liquid in your hand?
When you hold a liquid in your hand, the liquid will conform to the shape of your hand due to gravity. Your hand will apply pressure on the liquid, and depending on the liquid's properties (viscosity, density), it may flow between your fingers or remain in place.
What is the density independent of lava flow?
the lava flow is a density independent that flow good from the chemicals lava it have to flow and it is independent
