Answer to Question #244423 in Physics for Kimberly

Question

 A) The rate of flow of thermal energy 𝑄 𝑡 in a material is given by; 𝑸 𝒕 = 𝑪𝑨𝑻 𝑿

Where: 𝐴 is the cross − sectional area of the material,

𝑇 is the temperature difference across the thickness of the material,

𝑋 is the thickness of material,

𝐶 is a constant. Determine the SI base units of �

Answer 1

The SI base unit of C is

$$[C]=\frac{[Q_t]}{[A][T][X]}=\frac{\text{kg m}^2\text{s}^{-2}}{\text{m}^2\text{K} \text{ m}}=\text{ kg m s}^{-3}\text{K}^{-1}.$$
