The problem of the origin of the Earth is essentially astronomical rather than geological because geological history is considered to have begun when common Earth processes, such as erosion, deposition, and transportation of sediments, etc., were brought into play. It is quite certain, however, that the Earth in its pre-geologic state gradually merged into its …
In a stationary fluid, the atoms or molecules have two motions: Diffusion due to Brownian motion and Vibratory motion around their mean positions. The forces on the fluid molecules are such that the molecule of fluid can easily slide by the side of another molecule. Hence diffusion is predominant in liquids and gases. When a …
Thermal Equilibrium: By the touch of our hand, we can roughly determine which is the hottest or coldest object. The hotness or coldness of an object was called temperature. If two objects give the same feeling of being equally hot (or cold), they are said to have the same temperature, and objects are said to …
