Thank you!DrDu said:R="Rest", is a generic abbreviation for that part of the molecule which is not explicitely drawn, e.g., an ethyl group. "Finely divided" means a very fine powder which has a high specific surface.
'R' in the figure refers to the symbol for the gas constant, which is a fundamental physical constant used in many scientific calculations. It is typically denoted by the symbol 'R' and has a value of 8.3145 joules per mole-kelvin.
'R' is important in science because it is a fundamental constant that relates the energy of a system to its temperature and the number of particles present. It is used in various equations, such as the ideal gas law, to calculate the behavior of gases and other substances under different conditions.
'R' is calculated and measured through various experimental methods, such as measuring the properties of gases at different temperatures and pressures. It can also be derived from other fundamental constants, such as Avogadro's number and the Boltzmann constant.
Yes, 'R' is considered a universal constant as it is used in a wide range of scientific fields, including chemistry, physics, and thermodynamics. It has the same value across different systems and is not affected by the specific properties of the substances being studied.
Yes, 'R' can be used for any type of gas as it is a general constant that applies to all gases, regardless of their chemical or physical properties. However, its value may vary slightly depending on the units used for temperature and pressure in different systems.
