What are attractive forces?
Definitions of attractive force. noun. the force by which one object attracts another. synonyms: attraction. see more.
Can liquids flow?
Like the particles of a solid, particles in a liquid are subject to intermolecular attraction; however, liquid particles have more space between them, so they are not fixed in position. Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume.
What are the 5 properties of liquid?

What are three examples of liquids?
Examples of Liquids
- Water.
- Milk.
- Blood.

- Gasoline.
- Mercury (an element)
- Bromine (an element)
- Wine.
Why it is easy to pour a liquid?
liquid particles are not packed as tightly as in the case of solids,nor these are as free as the particles in the gaseous form so this makes liquid easier to pour(the average packing of the particles).
Which liquid flows freely to ground?
The viscosity of a liquid is a measure of its resistance to flow. Water, gasoline, and other liquids that flow freely have a low viscosity. Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 1, have higher viscosities.
Does liquid occupy space?
A liquid can be poured and will take on the shape of the container that it is poured into. Except for water, most liquids have particles which take up more space than they do when they are in their solid state. The particles in liquids can move around and slide past each other.
How does the liquid flows?
A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Like a gas, a liquid is able to flow and take the shape of a container. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density.
What are 3 facts about liquid?
Liquid facts for kids
- A liquid is a form of matter.
- Every small force makes a liquid change its shape by flowing.
- Fluids that flow slowly have a high viscosity.
- It is difficult to compress a liquid.
- Examples of liquid are water, oils and blood.
What is liquid short answer?
A liquid is a sample of matter that conforms to the shape of a container in which it is held, and which acquires a defined surface in the presence of gravity. When a liquid is cooled, the atoms or molecules lose kinetic energy. If the temperature becomes low enough, the liquid becomes a solid. Water is a good example.
Can liquid exist in a vacuum?
2 Answers. No liquid can be completely stable in a vacuum, since all liquids have some non-zero vapour pressure, and so will evaporate at some rate. However some liquids have an exceptionally low vapour pressure, and so can be used in a vacuum.
Do humans explode in space?
The vacuum of space will pull the air from your body. So if there’s air left in your lungs, they will rupture. Oxygen in the rest of your body will also expand. You’ll balloon up to twice your normal size, but you won’t explode.
What happens if you put water in a vacuum?
Originally Answered: What happen with water in vacuum? It will boil, freeze, and sublime. Once the air pressure is reduced low enough, water will boil at room temperature. That process causes it to become colder, until it literally boils and freezes simultaneously (this is known as the triple point).
What happens to liquids in a vacuum?
Vacuum evaporation is the process of causing the pressure in a liquid-filled container to be reduced below the vapor pressure of the liquid, causing the liquid to evaporate at a lower temperature than normal.
Does water freeze instantly in space?
Key Takeaways: Would Water Boil or Freeze in Space? Water immediately boils in space or any vacuum. Space does not have a temperature because temperature is a measure of molecule movement. After water vaporizes in a vacuum, the vapor could condense into ice or it could remain a gas.
How does liquid behave in a vacuum?
If you pull a vacuum on a liquid, when the ambient pressure exerted on the liquid falls to the vapor pressure of the liquid at that temperature, the liquid starts to boil. Pulling such a vacuum very suddenly on a sample of water will cause the water to explode violently into vapor by boiling all at once.
How do you instantly evaporate water?
TL;DR: When trying to make water evaporate quickly, it is best to spread the water over a large surface area and apply heat as evenly as possible. If using hot air to evaporate water, increased velocity will increase the speed of evaporation.
How hot would it have to be for water to instantly evaporate?
You’re sort of right. Above 212°F at standard pressure, liquid water is unstable. It will evaporate very rapidly from the surface. If the temperature is held constant (which requires some heat input, since evaporation cools things) the liquid will all evaporate.
What is the process called when a liquid turns into a gas?
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. Like the solid/liquid phase change, the liquid/gas phase change involves energy.
Does it have to be hot for water to evaporate?
Heat (energy) is necessary for evaporation to occur. Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point (212° F, 100° C) but evaporates much more slowly at the freezing point.
Does water evaporate on high or low heat?
They stay in the atmosphere, affecting humidity, or the amount of moisture in the air. Areas with high temperatures and large bodies of water, such as tropical islands and swamps, are usually very humid for this reason. Water is evaporating, but staying in the air as a vapor.
Can liquid evaporate without boiling?
The heat in that water results in some molecules moving fast enough to escape into the air, that is, evaporate. No additional source of energy is required for evaporation, and the water does not need to reach the boiling point to evaporate.
Does water evaporate faster with or without a lid?
A covered pot boils faster than an uncovered one because the cooling presence of the room’s atmosphere is greatly diminished. Once the liquid comes to a boil, the options widen. With placement of the lid, you are attempting to juggle the competing considerations of boil-over, sufficient heat and evaporation.
What are the three differences between evaporation and boiling?
| Differences between Evaporation and Boiling | |
|---|---|
| Evaporation usually occurs on the surface of the liquid being heated up. | Boiling usually occurs on the entire mass of the liquid that gets heated up. |
| Bubbling effect is not visible in evaporation. | Bubbling effect is visible during the process of boiling. |
What is the difference between vaporization and boiling?
Vaporization (or vapourisation) of an element or compound is a phase transition from the liquid phase to vapor. The point where the liquid changes into gaseous state at a given pressure and temperature is called as ‘Boiling Point’. The boiling point of the water is 100°c at normal atmospheric pressure.
