Why do substances exist as a solid liquid and gas?

Why do substances exist as a solid liquid and gas?

Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic energies of the particles (atoms, molecules, or ions) that make up a substance. Kinetic energy tends to keep the particles moving apart. The attractive intermolecular forces between particles that tend to draw the particles together.

Why are some substances found in the solid state some in the liquid state and others in the gaseous state?

For many substances, solid, liquid and gaseous states exist at the correct temperature and pressure. Any solid compound which decomposes upon heating will never be found in the liquid state, but sometimes very low pressure and laser excitation can turn the solid into a gas.

Why do some substances exist as a solid others as liquid and others as a gas when at the same temperature?

Each substance is different however, as you have pointed out. Gold is solid at room temperature, mercury is a liquid, and neon is a gas. The reason for the difference is that they all have different elemental properties. Since there are no forces, they are free to move around and, therefore, are a gas.

Why do some substances exist as solid?

When the constituent particles of a substance are so closely packed that the intermolecular forces of attraction are much stronger than the thermal energy, the substance exists as a solid.

Why are gases compressible but not liquids?

Why are gases compressible but not liquids? Answer: Gases are compressible because the intermolecular space is very large in gases, whereas liquids are not compressible because in liquids, the intermolecular space is less.

Which substances exist in liquid state?

Only two elements are liquid at standard conditions for temperature and pressure: mercury and bromine. Four more elements have melting points slightly above room temperature: francium, caesium, gallium and rubidium.

Why does solid and liquid exist?

Until now, the atoms in physical material were understood to exist typically in one of three states – solid, liquid or gas. Chemical interactions between atoms in one lattice are strong, meaning they stay in a solid form when the structure is heated, while the other atoms melt into a liquid state.

Can all gases become solid?

Under certain circumstances, gas can transform directly into a solid. This process is called deposition. Water vapor to ice – Water vapor transforms directly into ice without becoming a liquid, a process that often occurs on windows during the winter months.

What is a gaseous state of substance that is a liquid or solid at room temperature?

Water vapor
Water vaporThe distinction between a gas and a vapor is subtle: the term vapor refers to the gaseous form of a substance that is a liquid or a solid under normal conditions (25°C, 1.0 atm).

Which substances are solids liquids or gases?

Water is the only common substance that is naturally found as a solid, liquid or gas.

Why are gases compressible but not solid?

There is no space between the individual particles, so they cannot pack together. The kinetic-molecular theory explains why gases are more compressible than either liquids or solids. Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles.

Why do most covalent compounds exist in gases liquids and solids?

Covalent compounds have weak intermolecular forces ( vanderwaal forces) of attraction between them which leads to there low m.p & b.p. And hence most of the covalent compounds exist in gases, liquids, and soft solids.

What is the difference between solids liquids and gases?

Solids, Liquids and Gases. In the solid and liquid states, the ions or molecules are very close, whereas in the gaseous state, these particles are separated by relatively large distances. In the solid state, the ions or molecules do not translate; that is, they move around within the rigid form that constrains them.

Can ionic compounds exist as solid liquid and gas?

The answer is no. Even after vaporization, ionic compounds do retaining some oftheir compound oriented properties, existing as monomers and dimers . So, there you have it – ionic compounds can exist as solid, liquid and gas depending on the conditions they are exposed to.

Is water a solid liquid or gas at 100 degrees?

Water, on the other hand, is a liquid and boils at 100 °C. It also has greater viscosity, higher density, and greater surface tension than similar compounds.
