gas
Solids. They are most resistant to outer forces; but strictly speaking all materials are compressible.
The solid state of matter is most resistant to compression because the particles are tightly packed together and have minimal space to move. This makes it difficult to compress solids compared to liquids and gases.
The most important is the liquefaction of gases.
The solid state of matter is the most rigid because the particles are closely packed together and have little room for movement. This results in a fixed shape and volume, making solids resistant to deformation.
Most elements exist in the state of matter known as solids at room temperature and pressure. Some elements can also exist as liquids or gases depending on the conditions.
At 28°C and 0.7 ATM, the substance will most likely be in the gaseous state as it is above the boiling point of most substances at that pressure.
Nitrogen is a colorless, odorless gas at room temperature and pressure, making it the most common state of matter for nitrogen in the Earth's atmosphere.
The most common state of matter for water is liquid.
The matter for most elements is a solid.
Solids are the most dense state of matter
Pressure affects states of matter by influencing the intermolecular forces between particles. Increasing pressure can push particles closer together, overcoming the forces that keep them in a specific state. For example, increasing pressure on a gas can cause it to condense into a liquid or solid. Conversely, decreasing pressure can allow particles to move further apart, leading to a change in state such as a solid sublimating directly into a gas.
Magnesium is a solid at room temperature and pressure. It exists in a crystalline form with a metallic luster.
