What is force of attraction?
a force between two bodies, molecules, particles, or the like, that attracts each to the other. … Gravity is the force of attraction between two bodies that have mass.
What is meant by intermolecular forces of attraction?
Intermolecular forces are the forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions ). These forces are weak compared to the intramolecular forces, such as the covalent or ionic bonds between atoms in a molecule.
What is vanderwall force of attraction?
van der Waals forces, relatively weak electric forces that attract neutral molecules to one another in gases, in liquefied and solidified gases, and in almost all organic liquids and solids. … The tendency of such permanent dipoles to align with each other results in a net attractive force.
What is the force of gravity between Earth and Venus?
Since Venus and Earth are almost the same size and have about the same mass, the surface gravity on Venus is almost the same as the surface gravity on Earth. The surface gravity on Venus is about 91% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 91 pounds on Venus.
What is intermolecular force of attraction for Class 7?
The force of attraction between the molecules of matter is called the intermolecular force of attraction. It is maximum in solids, less in liquid and least in gases.
What are the types of intermolecular forces of attraction?
There are three types of intermolecular forces: London dispersion forces (LDF), dipole- dipole interactions, and hydrogen bonding.
