What is the definition of cohesion force?
Cohesion force refers to the attractive forces between molecules of the same substance, causing them to stick together. These forces are responsible for phenomena like surface tension and capillary action. Cohesion is essential for the overall stability and properties of liquids.
What property of water causes many of its properties?
Hydrogen bonding is the property of water that gives rise to many of its unique characteristics, such as high surface tension, high specific heat capacity, and low density in solid form. These properties are a result of the strong attraction between water molecules due to hydrogen bonding.
What is the difference between chemical and physical properties?
Chemical properties describe how a substance interacts with other substances to form new substances, such as reactivity or flammability. Physical properties describe the characteristics of a substance that can be observed or measured without changing its chemical composition, such as color, density, or melting point.
What force must be responsible to stick balloon on the wall?
The force responsible for sticking a balloon to a wall is called adhesion. This force occurs due to the attraction between the molecules of the balloon and the molecules of the wall, causing them to stick together.
What is an intermoleculecular force?
Intermolecular forces are weak interactions between molecules that hold them together. These forces include hydrogen bonding, dipole-dipole interactions, and London dispersion forces. They influence the physical properties of substances such as boiling point, melting point, and solubility.
What is the name of the gap between the molecules in a substance?
The gap between molecules in a substance is known as intermolecular space. This space varies depending on the substance and affects the physical properties of the material.
What is molecular physics?
Molecular physics is a branch of physics that studies the physical properties and behavior of molecules. It explores how atoms are bonded together to form molecules, their internal structure, and the interactions between molecules. Molecular physics plays a crucial role in understanding chemical reactions, materials science, and biological processes at a molecular level.
What is the meaning of intermolecular spaces?
Intermolecular spaces refer to the empty spaces or gaps between molecules in a substance. These spaces determine the physical properties of the substance, such as density and compressibility. The size of intermolecular spaces can affect how closely packed molecules are in a material.
What is an attraction between molecules of the same substance and why?
An attraction between molecules of the same substance is called cohesion. This occurs because molecules of the same substance have similar properties and are able to bond together through intermolecular forces such as hydrogen bonding or van der Waals forces. Cohesion is responsible for many properties of substances, such as surface tension in water.
Characteristics you use to tell the difference between kinds of matter are called?
Characteristics we use to tell the difference between kinds of matter are called _________ Properties?
What are viscosity properties?
it depends on the attrective force between the molecules
What physical properties are different for the isomers. explain.?
Isomers are molecules with the same molecular formula but different structural arrangements. Physical properties that can differ between isomers include boiling points, melting points, solubility, and density. These differences arise because the arrangement of atoms in isomers affects how the molecules interact with each other, leading to variations in physical properties.
What intermolecular forces are largely responsible for the interaction between hexane molecules and fat molecules?
obesity
Why do polar nonpolar molecules have different properties?
Compounds differ because of differences in attractions between their molecules.
Why polar and nonpolar molecules have different properties?
Compounds differ because of differences in attractions between their molecules.
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Characteristics we use to tell the difference between kinds of matter are called?
These characteristics are chemical and physical properties.
