Why is E-stilbene solid and Z-stilbene liquid?
The attractive forces between the molecules in E-stilbene must be stronger than the attractive forces holding Z-stilbene together. The degree of attraction between molecules in a substance always accounts for its state of matter at a given temperature.
What happen to liquid in water?
When a solid is placed in water, it will dissolve if the attractive forces between the water molecules and the solid molecules are stronger than the forces holding the solid molecules together. If the solid does not dissolve, it may remain suspended in the water as a suspension or sink to the bottom as a sediment.
Are the forces in animal fats attractive?
Yes, the forces in animal fats are primarily attractive. These attractive forces include van der Waals forces and dipole-dipole interactions between the fatty acid molecules. These interactions contribute to the solid or semi-solid state of animal fats at room temperature, affecting their texture and melting points.
Is the force of attraction stronger in the molecules of a solid or liquid?
The force of attraction is generally stronger in the molecules of a solid compared to a liquid. In a solid, the molecules are closely packed and have limited movement, allowing for stronger intermolecular forces to hold them together. In a liquid, the molecules have more freedom to move, resulting in weaker intermolecular forces.
What keeps the particles in a solid in their arrangement?
In a solid, the particles are held together by strong attractive forces between them, such as metallic, covalent, or ionic bonds. These forces prevent the particles from moving freely and maintain their fixed positions in the solid's arrangement.
Why is bromine2 a liquid and Iodine 2 is a solid?
Iodine has stronger intermolecular forces.
Glycerol boils at a slightly higher temperature than does water. this reveals that glycerols attractive forces are?
Glycerol's higher boiling point compared to water indicates that glycerol molecules have stronger intermolecular forces, such as hydrogen bonding or dipole-dipole interactions. These stronger attractive forces require more energy to overcome, resulting in a higher boiling point for glycerol.
What are the relative strength strengths of attractive and repulsive forces in a stable nucleus?
In a stable nucleus, the attractive nuclear forces (such as the strong nuclear force) are stronger than the repulsive forces (such as the electromagnetic force) between protons. This balance of forces keeps the nucleus stable and prevents it from breaking apart.
In a solid what is the attraction between particles?
Solids are held together but different types of intermolecular forces. The nature of these forces depends on the compound. In nonpolar substances, only dispersion forces at work. In polar compounds, dipole-dipole forces also hold the molecules together. Since dipole-dipole forces are stronger than dispersion forces, polar compounds usually have a higher melting point than nonpolar ones.
What do we need to break the attractive forces between the particles of a solid?
To break the attractive forces between the particles of a solid, sufficient energy must be supplied to overcome the intermolecular or ionic bonds holding the particles together. This energy can be provided in the form of heat, which raises the temperature and increases the kinetic energy of the particles, allowing them to move apart. Additionally, mechanical forces can also be applied to disrupt the structure of the solid.
what do we need to add to break the attractive forces between the particles of a solid?
keep them from position is a inter molecular bond
A difference between electric forces and gravitational forces is that electrical forces include?
Electrical forces include both attractive and repulsive interactions between charged particles, whereas gravitational forces are always attractive between objects with mass. Additionally, electric forces are much stronger than gravitational forces, but they have a shorter range.
