If the intermolecular forces are great enough they can hold the molecules together as a liquid. If they are even stronger they will hold the molecules together as a solid.
Water has nearly the same mass as methane and ammonia molecules, but the greater molecular forces between water molecules causes the water to be liquid at room temperature, while ammonia and methane, with weaker intermolecular forces, are gases at room temperature.
What else can I help you with?
How do you determine the physical state of a compound?
The physical state of a compound is determined by its intermolecular forces. Solids have strong forces, liquids have moderate forces, and gases have weak forces between their molecules. Factors such as temperature and pressure also play a role in determining the physical state of a compound.
Most substances are?
Most substances are either solids, liquids, or gases at room temperature, depending on their molecular structure and intermolecular forces. The state of a substance can change with temperature and pressure.
What is the chief factor that determines the physical state of a sample of matter?
The chief factor that determines the physical state of a sample of matter is the intermolecular forces present between its particles. These forces determine how closely the particles are packed together and how they move, leading to the distinctive properties of solids, liquids, and gases.
Intermolecular forces that must be overcome to convert H2Se to gas?
The intermolecular forces that must be overcome to convert H2Se (hydrogen selenide) to gas are London dispersion forces and dipole-dipole interactions. These forces hold the H2Se molecules together in the liquid state. As energy is added to the system, these intermolecular forces weaken, allowing the molecules to overcome the attractive forces and transition into the gaseous state.
The boiling point of a molecular compound depends on the strength of?
the intermolecular forces between the molecules in the compound. Strong intermolecular forces, such as hydrogen bonding or dipole-dipole interactions, result in higher boiling points because more energy is required to overcome these forces and transition from a liquid to a gas state. Conversely, weaker intermolecular forces lead to lower boiling points as less energy is needed for the molecules to separate.

What are the factors affecting the states of matter?
Factors affecting states of matter include temperature, pressure, and intermolecular forces. As temperature increases, substances can change from solid to liquid to gas. Pressure can also affect the state of matter, with higher pressure favoring a more condensed state. Intermolecular forces determine how tightly particles are held together in a substance, influencing its state.
Why do different substances require different amount of heat energy during melting?
The amount of heat energy needed to melt a substance depends on its molecular structure and the strength of the intermolecular forces holding its particles together. Substances with stronger intermolecular forces require more heat energy to overcome these forces and change from a solid to a liquid state. Conversely, substances with weaker intermolecular forces require less heat energy to achieve the same phase change.
Some substances evaporate more easily than other because they?
have weaker intermolecular forces, which allow the molecules to escape into the gas phase more readily.
Most substances are?
Most substances are either solids, liquids, or gases at room temperature, depending on their molecular structure and intermolecular forces. The state of a substance can change with temperature and pressure.
Name four factors upon which a substances state depends?
The state of a substance depends on temperature, pressure, molecular structure, and intermolecular forces. These factors determine whether a substance exists as a solid, liquid, or gas at a given time.
Why two different substances have different melting point?
Different substances have different melting points because the strength of intermolecular forces (such as hydrogen bonding, dipole-dipole interactions, and London dispersion forces) vary between substances. Substances that have stronger intermolecular forces require more energy to overcome them, resulting in a higher melting point. Conversely, substances with weaker intermolecular forces have lower melting points as they require less energy to transition from solid to liquid state.
What is the chief factor that determines the physical state of a sample of matter?
The chief factor that determines the physical state of a sample of matter is the intermolecular forces present between its particles. These forces determine how closely the particles are packed together and how they move, leading to the distinctive properties of solids, liquids, and gases.
Why molecular substances with weak intermolecular forces have low melting points?
The cause is just this weak intermolecular force, ease to be broken.
Intermolecular forces that must be overcome to convert H2Se to gas?
The intermolecular forces that must be overcome to convert H2Se (hydrogen selenide) to gas are London dispersion forces and dipole-dipole interactions. These forces hold the H2Se molecules together in the liquid state. As energy is added to the system, these intermolecular forces weaken, allowing the molecules to overcome the attractive forces and transition into the gaseous state.
Substances that can be transformed to a gas at relatively low temperatures are termed?
Substances that can be transformed into a gas at relatively low temperatures are called volatile substances. These substances have weak intermolecular forces that allow them to readily transition from a liquid or solid state to a gas at lower temperatures compared to non-volatile substances.
Can you please-Compare the melting points of substances that are gases at room temperature with solids and liquids?
Substances that are gases at room temperature typically have lower melting points than solids and liquids because their intermolecular forces are weaker. Gases have molecules that are further apart, making it easier to overcome these weak forces to change their state. Solids and liquids have stronger intermolecular forces that require more energy to break, resulting in higher melting points.
