## 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.
