problems and solutions on solid state physics

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 miniat..

Properties of Matter - A solid has certain characteristics: According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Soli..

The States of Matter - Matter occurs in four states: Solid, Liquid, Gas and Plas..

The molecules in a solid are very closely packed. The inter-molecular force of attraction is very strong in solids. Hence solids have a definite size and shape. Molecules of a solid vibrate about their mean positio..

Normally matter exists in three forms: Solid Liquid Gases Heat energy can bring about a change of state in matter from solid to liquid and liquid to gaseous state. Suppose a solid is heated continuously at constant pressure, its temperature goes on ..

. We call it an equation of state even when we do not know the actual equation. Here's a simple (though approximate) equation of state for a solid material. The temperature coefficient of volume expansion b is the fractional volume change per unit temperature change, a..

. But, the actual result shows anomaly. This was not explained at that time. However, Planck propounded quantum theory in 1905. Einstein applied it to specific heat problem in 1907. Ultimately, Debye was successful in 1912, in fully explaining the thermal behavior of metals and non-metals..

Matter is made up of atoms and molecules. These atoms in molecules are in a state of continuous motion. For example, molecules and atoms of a solid can have only vibrational motion, because they are held in their positions by strong intermolecular force..

Calorimetry is the measurement of the amount of heat evolved or absorbed in a chemical reaction, change of state, or formation of a solution..
