The bar graph shows the temperatures recorded on May 3 rd , in three different states. Which state recorded the minimum temperature? => Texas or Michigan or Arizona or Alabama..
State variable
A measurable property required to describe the state of a system is called state variable. For example, temperature (T), pressure (P), volume (V) etc. are the state variables. For any system, a certain minimum number of variables are sufficient to define its..

The box plot represents the five-number summary of the temperatures recorded at a particular place in California state for the first week of April 2003. The recorded temperatures in °F are 87, 85, 80, 78, 83, 86, 90. Find maximum temperature, minimum temperature and interqua..
Biological Rhythms
A rhythm is a recurring process which is wave like in character, because maximum and minimum states appear at identical intervals of tim..
Theorem 5
Let f be a differentiable function on I and let x 0 be any interior point of I. Then (a) If f attains its absolute maximum value at x 0 , then f ' (x 0 )= 0 (b) If f attains its absolute minimum value at x 0 , then f '(x 0 ) = 0. In view of the above theorems, we state the fol..
Hund's Rule of Maximum Multiplicity
. In state (b), the two electrons are present in different orbitals but with opposite spins while in state (c), the electrons are present in different orbitals with same spins. Now, the electrons are charged particles and repel one another. The electron-electron repulsions are h..
Intermolecular Forces and Interatomic Forces
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..

The principle of quantisation of electric charge states that "in nature there is a smallest amount of charge and all other charges are integral multiples of this smallest unit ". That is, if e is the minimum charge then the total charge on the body is equal to ne where n is an ..
Excitation and Ionisation Potential
An electron revolving in a stationary orbit of an atom absorbs some energy the electron may jump over to an orbit of higher energy. This process is called excitation and the atom is said to be in the excited state. The energy absorbed to move from one orbit to the other is called excitati..

The symbols and formulae of the reactant and products are written as a skeletal equation. Any elementary gas (O 2 , H 2 , N 2 etc.) appearing on either side of the skeletal equation, is written in the atomic state. The formula containing the maximum number of atoms is selected to begi..
