Which equation is ideal gas?
The empirical relationships among the volume, the temperature, the pressure, and the amount of a gas can be combined into the ideal gas law, PV = nRT.
What is ideal gas equation class 11?
PV =m/M × RT. The equation is called as an ideal gas equation. R = Molar gas constant. Where P1, V1, T1, are the initial pressure, and, volume and tempera and P2, V2, T2are final pressure, volume and temperature.
What does PV nRT stand for?
universal gas law
What is SI unit of R?
The ideal gas law is: pV = nRT, where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K.
What is the dimensional formula of current?
= [M0 L0 I1 T1] × [M0 L2 T0]-1 × [M0 L0 T1]-1 = [M0 L-2 T0 I1]. Therefore, the current density is dimensionally represented as [M0 L-2 T0 I1].
What is an ideal blackbody?
An ideal body is now defined, called a blackbody. A blackbody allows all incident radiation to pass into it (no reflected energy) and internally absorbs all the incident radiation (no energy transmitted through the body). Hence the blackbody is a perfect absorber for all incident radiation.
What is the formula of radiation?
The rate of heat transfer by emitted radiation is determined by the Stefan-Boltzmann law of radiation: Qt=σeAT4 Q t = σ e A T 4 , where σ = 5.67 × 10−8 J/s · m2 · K4 is the Stefan-Boltzmann constant, A is the surface area of the object, and T is its absolute temperature in kelvin.
