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.

To reduce heat flux, the skin is wrapped with a clothing material. What should be the thickness of the clothing material covering the surface of this skin tissue to reduce the heat flux to half of its original value? What is the temperature at the skin-clothing material interface? Note: if you think you need to have more information to solve this problem, you're free to make assumptions. Please state them clearly in your answer, if you need to make such assumptions.
A composite wall is made up of an external thickness of brickwork 110 mm thick inside which is a layer of fiberglass 75 mm thick. The fiberglass is faced internally by an insulating board 25 mm thick. The coefficients of thermal conductivity are as follow: Brickwork 1.5 W/m-K Fiberglass 0.04 W/m-K Insulating board 0.06 W/m-K The surface transfer coefficients of the inside wall is 3.1 W/m²-K while that of the outside wall is 2.5 W/m²-K. Take the internal ambient temperature as 10°C and the external temperature is 27°C. Determine the heat loss through such wall 6m high and 10 m long. Badly needed asap. I will rate helpful. Thank you in advance.
A 5cm copper plate has a thermal conductivity of 395 ?/m-k is used as a heat sink for a semiconductor. A 1mm layer of thermal paste lies in between the two and it has a thermal conductivity of 10 ? /m-k. Solve for the heat transferred at a 5cmx5cm area if the semiconductor is 80C, while the copper plate has a temperature of 30C since it is exposed to ambient air temperature.
