AI Generated Solution

To understand why felt is a better heat insulator than air, despite air having a lower thermal conductivity than felt, we can break down the explanation into several steps: ### Step 1: Understand Thermal Conductivity Thermal conductivity is a measure of a material's ability to conduct heat. A lower thermal conductivity means that the material is less effective at transferring heat. ### Step 2: Compare Air and Felt - **Air**: Air has a lower thermal conductivity compared to felt. This means that, in theory, air should be a good insulator. - **Felt**: Felt has a higher thermal conductivity than air, which suggests that it can transfer heat more effectively than air. ...

Statement I: Two solid cylindrical rods of identical size and different thermal conductivity K_1 and K_2 are connected in series. Then the equivalent thermal conductivity of two rods system is less than that value of thermal conductivity of either rod. Statement II: For two cylindrical rods of identical size and different thermal conductivity K_1 and K_2 connected in series, the equivalent thermal conductivity K is given by (2)/(K)=(1)/(K_1)+(1)/(K_2)
