The third law of thermodynamics deals with the entropies of the perfect crystalline substances at absolute zero of temperature. According to third law of thermodynamics: At absolute zero the entropy of a perfectly crystalline substance is taken as zero. This law was first formul..

Usually the amount of water vapor is less than the absolute value at a given temperature. Relative humidity is defined as the ratio of the actual amount of water vapor in the atmosphere to the absolute humidity at that temperature. For example, suppose air co..

Every substance has a definite value of enthalpy in a particular state. Like internal energy, the absolute value of enthalpy cannot be measured. However, the change in enthalpy accompanying a process can be determined as the difference between the enthalpies..

Take the maximum and minimum values of f out of the values calculated in step 3. These will be the absolute maximum or absolute minimum values..

Let f be a continuous function on an interval I = [a, b]. Then, f has the absolute maximum value and f attains it at least once in I. Also, f has the absolute minimum value and attains it at least once in ..

Graphical representation of Complex numbers - The complex number Z = x + iy may be represented graphically by the point P whose rectangular co-ordinates are (x, y). Thus each point in the plane is associated with a complex number. In the figure, P defines Z = x + iy. It is customary to ch..

Internal Energy and Change in Internal Energy - Since chemical changes are always accompanied by energy changes, it indicates that reactants and products must be having certain amounts of energy. A fixed quantity of any substance is associated with a definite amount of energy, which depen..

We use specific number of digits to denote an exact value of a number for required accuracy. The digits used for such a purpose are called significant figures. The difference between these two values is called the absolute error. Absolute Error = ..

.16 K, keeping the volume V the same as that at T. From equation (v), From the definition of absolute temperature scale, From (viii) and (ix), Now, v t r is the rms speed of the molecules at 273.16 K and hence, is constant for a given gas. Equation (x) shows that the absolu..
