Properties of Gases
Pressure of Gas
The formula for the change in volume of a gas with the change of pressure and heat is called the formula of gas.
 Boyle’s Law: – If the temperature is constant, the volume of gas, the gas pressure in any given mass varies with the byastanupate.
- The mathematical form of Boyle’s formula: If the volume of gas of a certain mass is V and its pressure is P, then V of the Boyle formula
∝ 1/ P, If the warmth persists. Or, PV = constant. If the pressure of a certain mass of gas in constant heat is P1, P2, P3, and the volume is V1, V2, V3, etc., then according to Boyle’s formula P1V1 = P2V2 = P3V3 = K (constant).
 Charles’ Law’s: – pressure is fixed, the size of the mass of gas per degree Celsius increase in temperature or temperatures 0-degree C to reduce the volume of the gas, its 1/273The portions increase or decrease, respectively. 1/273The fraction is called the volume expansion coefficient of gas at constant pressure.
Explanation of the formula
According to Charles’ formula, suppose the volume of a certain mass of gas at 0-degree-C heat = Vo.
So according to Charles’s point,
The Absolute Scale of Temperature and Absolute Zero
Absolute Zero: – Charles can be seen from the formula, 0-degree-C to reduce the temperature of the mass of the volume of gas , Where Vo = 0-degree-C is the volume of that gas in heat. If the warmth can be reduced from 0-degree-C to 273-degree-C; That is, the gas volume is heated to
That means the gas will not occupy any volume during that heat.
The above phenomenon indicates minimum warming, given that the heat of a certain mass does not occupy any volume. Although it is possible in numbers, in reality it is impossible. Before the volume is practically zero, the gas becomes liquid. Regardless of the numerical rule, it is not possible to imagine a temperature lower than -273-degree-C, because then the volume of the gas is negative. Negative volume is meaningless. So it can be said that in the world no warming can be less than -273-degree-C. For this reason -273-degree-C warming is called extreme or absolute zero warmings.
- Definition: – According to Charles’s formula, no gas of a certain mass of heat occupies a volume; That is, the volume is zero — it is called absolute zero warmth.
The absolute scale of heat or Kelvin scale: – 273-degree-C is the absolute scale of warmth, or the Kelvin scale when the temperature is equal to one degree Celsius and the degree of heat is equal to one degree Celsius. If 1 degree Celsius and 1 Absolute scale equal degree C, any heat on the Celsius scale will be converted to toC absolute scale, T = (273 + t) K. According to this scale, the absolute warmth is denoted by the uppercase T and the Kelvin (K) unit is expressed (not Ko). So, on this scale, the freezing point of water is 0-degree-C= 273K, the boiling point of water is 100-degree-C = 373K, and any warming t-degree-C = (273 + t) K = TK.
Alternative form of Charles’s law
Standard Temperature and Pressure, STP
An ideal gas equation or equation of state
The combination of Boyle and Charles PV = KT The constant K value of the equation depends on the gas mass. For one gas, that is, one mole, the value of constant K is the same for any gas. This constant is expressed with the letter R. The constant R is called the universal gas constant or the molar gas constant. In the case of a mole gas, the PV = RT equation is called the ideal gas equation or the equation of conditions. The ideal gas equation for n -mol gas is PV = nRT
Universal gas constant: – The value of constant R of the standard gas equation PV = RT does not depend on the nature and religion of the gas. It is the same for all gases. Therefore, R is called a universal gas constant. R = 8.31 x 107 arg / mole K = 8.31 zol / mole K; Since 1 Jul = 107 arg.
