**WHAT IS A in dimensional formula?**

Hint – Dimension formula is **the expression for the unit of a physical quantity in terms of the fundamental quantities**. The fundamental quantities are mass (M), Length (L) and time (T). A dimensional formula is expressed in terms of power of M, L and T.

Dimension Formula of Boltzmann Constant

R is the universal gas constant, whose value is 8.314 J/K-mol, and its dimensional formula is **[[M^1L^2T^{-2}K^{-1}]]**.

**What does the K in K factor mean?**

Y factor and K factor are defined by the location of the sheet metal material’s neutral bend line with respect to the thickness. … The length of the neutral bend line is equal to the developed length. K factor is **a ratio between the distance from the neutral bend line to the inside bend radius and the material thickness**.

**Which R value is best?**

Depending on where you live and the part of your home you’re insulating (walls, crawlspace, attic, etc.), you’ll need a different R-Value. Typical recommendations for exterior walls are **R-13 to R-23**, while R-30, R-38 and R-49 are common for ceilings and attic spaces.

**What is K value of PVC?**

K-value. A characteristic of the PVC resin which describes the length of the polymer molecules. A measure of the molecular weight of PVC based on measurements of viscosity of a PVC solution. It ranges usually **between 35 and 80**.

**What is k in kT?**

kT (also written as k_{B}T) is the product of the **Boltzmann constant**, k (or k_{B}), and the temperature, T. … More fundamentally, kT is the amount of heat required to increase the thermodynamic entropy of a system by k.

**What is small k in physics?**

**Boltzmann constant**, (symbol k), a fundamental constant of physics occurring in nearly every statistical formulation of both classical and quantum physics.

**What is r in PV nRT?**

PV = nRT. The factor “R” in the ideal gas law equation is known as the “**gas constant**”. R = PV. nT. The pressure times the volume of a gas divided by the number of moles and temperature of the gas is always equal to a constant number.
