English Eng. Gas Constant: 8.314 J/mol-K

In summary, the English Engineering Gas Constant, also known as the Ideal Gas Constant, is a physical constant with a value of 8.314 joules per mole-kelvin (J/mol-K). It is used in chemistry, particularly in the Ideal Gas Law, to calculate the energy of gases at different temperatures and pressures. It is the same as the Universal Gas Constant, but is used in different contexts with different units of measurement. The value of the English Eng. Gas Constant was determined through experiments and calculations by physicists in the 19th century.

The equivalent value for the Universal Gas Constant in English Engineering is also 8.314 J/mol-K. This value is a fundamental constant in thermodynamics and does not change regardless of the unit system used. Therefore, it remains the same in both SI and English Engineering units.
 

FAQ: English Eng. Gas Constant: 8.314 J/mol-K

1. What is the English Engineering Gas Constant?

The English Engineering Gas Constant, also known as the Ideal Gas Constant, is a physical constant that relates the energy of a gas to its temperature and pressure. It is represented by the symbol R and has a value of 8.314 joules per mole-kelvin (J/mol-K).

2. What is the unit of measurement for the English Eng. Gas Constant?

The English Eng. Gas Constant has a unit of joules per mole-kelvin (J/mol-K). This unit represents the amount of energy per mole of substance per degree of temperature change.

3. How is the English Eng. Gas Constant used in chemistry?

The English Eng. Gas Constant is used in the Ideal Gas Law, which is a fundamental equation in chemistry that describes the behavior of ideal gases. It is also used in other thermodynamic equations to calculate the energy of gases at different temperatures and pressures.

4. What is the difference between the English Eng. Gas Constant and the Universal Gas Constant?

The English Eng. Gas Constant and the Universal Gas Constant are two different names for the same physical constant. The English Eng. Gas Constant is used in contexts where the unit of measurement is joules per mole-kelvin, while the Universal Gas Constant is used in contexts where the unit of measurement is energy per mole per degree of temperature.

5. How was the value of the English Eng. Gas Constant determined?

The value of the English Eng. Gas Constant was determined through experiments and observations of the behavior of gases. It was first calculated by the French physicist Jules Jamin in 1845 and later refined by the Italian physicist Stanislao Cannizzaro in 1860.
