Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Three of the following statements are true, but one is false. Indicate which one is false. O Insulation my increase or decrease the heat transfer from a pipe or a sphere. O There is no critical thickness of insulation for a flat surface (plane wall). O Small bodies with high thermal conductivities and low convection coefficients are less likely to satisfy the criterion for lumped system analysis. In a cylindrical pipe or a spherical shell, the additional insulation increases the conduction resistance of the insulation layer but decreases the convection resistance of the surface.
