Learning ObjectivesDefine, solid, liquid, and also gas.Explain differences amongst these three phases of matter.

Why is the state the water different in every picture?
Why is the state that water various in every picture?
Water can take many forms. At short temperatures (below 0°C), it is a solid. When at “normal” temperatures (between 0°C and 100°C), that is a liquid. While in ~ temperatures above 100°C, water is a gas (steam).
The state the water is in depends upon the temperature. Every state (solid, liquid, and also gas) has its very own unique set of physics properties.
Matter and Its States
Matter typically exists in one of three states: solid , liquid , or gas . The state a given substance exhibits is likewise a physics property. Some substances exist as gases at room temperature (oxygen and also carbon dioxide), if others, choose water and mercury metal, exist as liquids. Most steels exist as solids in ~ room temperature. All substances have the right to exist in any of these three states. In addition to existing in one of the 3 states, matter can also undergo a change the state. A change of state occurs when matter is converted from one state to one more state for example when a fluid is converted to a gas or a heavy is converted to a liquid.
Note: Technically speak a fourth state of matter referred to as plasma exists, however it does not naturally happen on earth, so we will certainly omit it from our study here.Liquid
Liquids have the complying with characteristics:no definite form (takes the form of its container)has definite volumeparticles are cost-free to relocate over each other, yet are still attracted to each other
A acquainted liquid is mercury metal. Mercury is one anomaly. That is the only metal we know of the is fluid at room temperature. Mercury additionally has an ability to stick to itself (surface tension) – a home all liquids exhibit. Mercury has a relatively high surface ar tension, which provides it really unique. Here you view mercury in its common liquid form.
If us were to warmth liquid mercury to its boiling suggest of 357°C, and also under the right push conditions, we would notice all corpuscle in the liquid state enter the gas state.Gas
Gases have the following characteristics:no definite shape (takes the shape of the container)no definite volumeparticles move in random activity with tiny or no attraction to each otherhighly compressibleSolid
Solids are defined by the adhering to characteristics:definite form (rigid)definite volumeparticles vibrate roughly fixed axes
If us were to cool liquid mercury to its freezing allude of -39°C, and under the right push conditions, us would an alert all the the liquid particles would enter the hard state.
The video below mirrors this process.
As you have the right to see in the video, mercury deserve to be solidified once its temperature is brought to its freezing point. However, once returned to room temperature conditions, mercury does not exist in solid state because that long, and returns back to its more common liquid form.

SummaryThree claims of issue exist – solid, liquid, and gas.Solids have a identify shape and also volume.Liquids have actually a identify volume, but take the shape of the container.Gases have actually no definite form or volume.
