ap physics bonding in solids

Solids have definite shape and volume because the average distance between the molecules or atoms remain constant and do not change with time. The arrangement of molecules inside a solid differ from one to another. This results in two types of solids Crystalline s..

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 valence el..

Fuels come in many varieties such as wood, cow dung, charcoal, kerosine and Liquified Petroleum Gas (LPG). These are used for cooking purposes. Coal, fuel, oil and natural gas are used in industries. Petrol and diesel are used in automobiles and locomotives. Specially prepared fuels are used in ro..

Introduction - A spider web is stronger than steel of the same thickness. Its elastic limit is greater than that of steel. A force is a push or pull exerted by one object or body on another. It may cause a body at rest to move or one in motion, to change its speed or direction. It may also change t..

Energy Bands in Solids - Atoms are clustered together and are overlapped in solids. Therefore, the outermost valence atoms are overlapp..

Tie the solid firmly with a thread and suspend it from the hook as shown in figure. Lower the solid in water as shown and find its weight (W 2 gf). Record the result as shown below: Weight of the solid in air: W 1 gf Weight of the solid in water = W 2 gf ..

Find the weight (W 1 gf) of a solid in air using a hydrostatic balance as shown in figure belo..

The cells discussed above use a liquid electrolyte, one cathode and an anode. Some of the major disadvantages of these cells are leakage on long term storage, corrosion due to the use of liquid acidic/alkaline solution, short life, low weightage per kg mass of the cell and limit on miniaturization...

Velocity of Sound in Liquids and Solids - modulus of the liquid r is its density. For water, at a temperature of 20 o C, B = 2.05 x 10 9 Nm - 2 and r = 1000 kmg -3 The velocity of sound in water was determined by Daniel Colladon and Jacob Sturm in the lake of Geneva in 1827. Two observers..
