Why does a liquid need a container?
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 liquid does not fill its container completely?
The forces of attraction between particles in a liquid are intermediate between solids and gases. These give the liquid a definite volume but not a definite shape. Therefore, a liquid take the shape of the container holding it but only occupies a volume equal to its volume.
What happens to a liquids shape in a container?
The movement of the particles causes the liquid to be variable in shape. Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume. The limited amount of space between particles means that liquids have only very limited compressibility.
Do liquids expand to fill their container?
Unlike a gas, a liquid is nearly incompressible, meaning that it occupies nearly a constant volume over a wide range of pressures; it does not generally expand to fill available space in a container but forms its own surface, and it may not always mix readily with another liquid.
Does the liquid flow Why?
As the particles in liquid have small between them, they have little force of attraction and thus, the particles are not tightly bound to each other. Now, as the particles have little spacing between them, the particles can be displaced or moved. Thus, the liquids flow.
Does not take the shape of its container?
A solid has a definite shape. It does not take the shape of its container. It also has a definite volume because it can be measured. A liquid does not have a definite shape.
What happens to water in an airtight container?
If the airtight container withstands the pressure during heating upon the water will return to its original state upon cooling. You will not lose any volume for any liquid that doesn’t undergo an irrevesible phase change. Mass of substance inside does not change because container is airtight.
What happens when a liquid evaporates?
Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. The water level will decrease as it is exposed to the heat of the sun.
What happens when a liquid is compressed?
A consequence of compressing a fluid is that the viscosity, that is the resistance of the fluid to flow, also increases as the density increases. This is because the atoms are forced closer together, and thus cannot slip by each other as easily as they can when the fluid is at atmospheric pressure.
What happens when two liquids do not mix?
When two liquids do not mix together and instead form layers, we call them “immiscible.”. The chemical properties of the liquids will determine if they will mix or not. Those with similar chemical properties will mix; those with different properties will not mix. Oil and water are good examples of immiscible liquids.
What is an unknown substance in a container?
An unknown substances could be a container with a label that has fallen off or faded so much you can’t read it. Alternately it could be a liquid in a plastic cup with a strange smell.
What kind of chemicals are in an unlabeled container?
Unlabeled chemical containers All chemical containers must display correct labels, this includes chemicals decanted or transferred out of their original container; chemicals manufactured in the workplace (including lab research and samples); and chemical waste. We’ll look at these separately below.
What happens when two liquids combine to form a gas?
In a liquid, the molecules are more loosely spaced. In a gas, the molecules are very far apart. Liquids do not have a fixed shape; they take on the shape of the container they are in. Most liquids can also flow and form drops. What’s happening? When two liquids combine to form a new liquid, we call the liquids “miscible.”
