The properties of a gas depends upon the temperature and pressure. Hence, it is convenient to specify a particular temperature and pressure for comparison of different gases. The standard conditions of temperature and pressure are abbreviated as S.T.P. (Standard Tempe..

Gay-lussac's law states that at fixed volume, for a given amount of ideal gas the pressure(P) is directly proportional to the absolute temperature(T). Which of the following curves represents the relationship between P and T. => Graph B or Graph C or Graph A..

At a given volume, the pressure of a given mass of a gas is proportional to its absolute temperature. This is Charle's law for pressure. This is the definition of the absolute temperature, T. If one starts from the fact that T and uses the fact that V i..

Humidity - Humidity is the amount of moisture (water vapor) present in the atmosphere. This moisture is due to the continuous evaporation of river, lakes, and oceans, and also from various life activities. At a given temperature, the maximum amount of water vapor that can be present is fixed. This ..

o t , because later on in the chapter, we use m for the mass of one molecule. Measurements of the behavior of various gases lead to several conclusions. First, the volume V is proportional to the number of moles n. If we double the number of moles, keeping pressure and temperature co..

. It is denoted by H. Mathematically, it may be put as H = E + PV Some important features of enthalpy are: (i) It is a state function. (ii) It is also called heat content of the system. (iii) Its value depends upon amount of the substance, chemical nature of the substance and conditions of temperat..

The third law helps to calculate the absolute entropies of pure substances at different temperatures. The entropy (S) of the substance at different temperature T may be calculated by the measurement of heat capacity changes. If S o be the entropy of the substance at 0 Kand S be its entr..

>Mathematical statement of Boyles' law is P 1 V 1 = P 2 V 2 = constant. Charles' law states that pressure remaining constant, the volume of a given mass of a dry gas is directly proportional to the Absolute temperature. Mathematical statement of Charles' law is Absolute..

>A plot of volume along x-axis and temperature along y-axis gives a straight line intercepting the y-axis. When this line is extrapolated to lower temperature, it cuts the x-axis, which represents the zero volum..

Lord Kelvin (1824-1907) devised this scale of temperature. Hence, this is called the Kelvin scale, and in this scale, temperature is expressed in Kelvin. In SI system, Kelvin is the unit of temperature. In this scale of temperature, zero of the scale corresponds to -273 0 C, which is said to be the..
