Obtain the dimensions of (1) coefficient of thermal conductivity (2) Gas constant (3) Boltzmann constant (4) Planck's constant.

Explanation

To find the dimensions of the coefficient of thermal conductivity, gas constant, Boltzmann constant, and Planck's constant, we will analyze each quantity step by step.

### Step 1: Coefficient of Thermal Conductivity (K)

The coefficient of thermal conductivity (K) is defined as:
\[ K = \frac{Q \cdot s}{A \cdot (T_1 - T_2)} \]

Where:
