intermolecular forces in ph3

Intermolecular Forces - The attractive forces between molecules are called intermolecular forces. Intermolecular attractions hold two or more molecules together. Intermolecular attractions can be of the following types: 1) Dipole..

When two wet glass plates are pressed together, they cannot be separated easily. This is because of the force of attraction existing between the atoms and molecules, and are electrical in origin. As the two isolated Hydrogen atoms approach each other, the nucleus of one atom attracts the ..

The ease of evaporation of a liquid is related to the strength of the attractive forces between the molecules in the liquid. In polar liquids cohesive forces are strong while in non-polar liquids the cohesive forces are very weak and the molecules escape easily. For e..

. An unbalanced force changes the state of constant velocity including zero velocity of a body on which it acts. Forces may be balanced or unbalanced. An iron ball suspended from a hook by a wire [Figure (a) shown below] has two forces acting on it, its weight, acting ..

Force And Motion - A vegetable vendor applies force to push the cart, a driver applies force either to stop the car or to change the speed or direction of motion and a football player kicks the ball to set it in motion. In all the above examples, the force ap..

Force of Gravitation - What do you observe when you drop a stone from a height? The stone which was initially at rest starts moving towards the ground and attains a maximum speed just before it touches the ground. Is the stone moving with a constant speed? No, it is not moving with unifor..

This kind of interaction is not well understood as yet. Its range is shorter than the nuclear force. It is important only for certain nuclear processes like radioactive beta decay. Strong : Electromagnetic : Weak : Gravitational 10 2 : 1 : 10 - 1 2 : 10 - 3 ..

Let us consider two situations Suppose a block of mass 'm' rests on a rough horizontal table. It is dragged horizontally towards right through a distance 'l', and back to its initial position. Let ' m ' be the coefficient of friction between the block and the table. Let us calculate the work done b..

Elastomers - Elastomers are polymers in which the polymer chains are held by weakest intermolecular forces. These forces permit the polymers to be stretched. A few cross links are introduced between the chains to help the polymer retract to its original position after ..
