random motion of molecules and their collisions with a surface

Heat and Motion (Kinetic Theory of Heat) - Under normal conditions matter exists in three forms: solid liquid gas Matter is made up of atoms and molecules. These atoms in molecules are in a state of continuous motion. For example, molecules and atom..

Evidence for Particulate Nature of Matter From Brownian Motion - When we look at a glass of still water on the table, it seems incredible that millions of molecules are moving about restlessly inside it. A British botanist called Robert Brown, however, discovered evidence of thi..

Every molecule in a gas is in a state of constant straight-line motion. Molecules very frequently collide with one another, and against the sides of the container (Fig. 15.4). It is assumed that the molecules do not lose energy during these collisions..

All the molecules of a liquid are in a state of constant and random motion. They have different velocities. During the motion, molecules collide against each other and some of the molecules gain more kinetic energy than others. The energy..

All the molecules of a gas are identical with respect to their shape and mass. The molecules of different gases are different. The gas molecules behave as rigid, elastic and smooth spheres. The size of gas molecules is very less when compared to the i..

>Matter consists of molecules. These are the smallest particles, which are capable of free existence and retain all the chemical properties of the parent substance. The molecules are always in a state of random continuous motion. The molecules exert forc..

In liquids, the molecules of the liquid are always in a state of random motion, within its surface. Some molecules may have sufficient kinetic energy to escape from the surface of the liquid. This process is known as evaporation. Eva..

Brownian movement was first discovered by Robert Brown, a botanist, in 1827. He observed that pollen grains in water do not remain at rest but move about continuously and randomly. This random continuous movement (Brownian motion) was observed in colloidal sol when th..
