Chapter 16: Problem 84

One purpose of foil facing on fiberglass insulation is to reduce heat loss by a. conduction. b. convection. c. radiation.

Short Answer

Expert verified
The foil facing on fiberglass insulation is intended to minimize heat loss primarily through radiation.

Step by step solution

01

Understand the Modes of Heat Transfer

Three types of heat transfer exist. First off is conduction, characterized by heat flowing through a solid material. Second, convection, which involves heat transfer by the movement of a fluid (liquid or gas). Lastly, radiation - this involves emission of energy due to temperature differences, even in a vacuum.
02

Determine the Purpose of Foil Facing

The purpose of foil facing on fiberglass insulation needs to be identified in relation to these types of heat transfer. The foil facing's reflective surface increases its resistance to heat transfer, particularly radiant heat. It acts as a radiant barrier, bouncing off the heat radiating towards it, thus minimizing heat transfer via radiation.
03

Match to Answer Option

From the above details, it is clear that the foil facing in fiberglass insulation significantly reduces heat loss by acting as a barrier to radiation. Therefore, the most suitable solution among the options given in the question would be radiation.

Fiberglass insulation for attics is available in 12 -inch thickness. Its \(\mathcal{R}\) -factor is a. 38 b. 76 c. 29

You bring a \(350-\mathrm{g}\) wrench into the house from your car. The house is \(15^{\circ} \mathrm{C}\) warmer than the car, and it takes \(2.52 \mathrm{kJ}\) to warm the wrench by this amount. Find (a) the heat capacity of the wrench and (b) the specific heat of the metal it's made from.

The table below shows temperature versus time for \(500 \mathrm{g}\) of water heated in a microwave oven. In a microwave, essentially all the microwave energy goes into the water-containing food in the oven. Plot the data, determine a best-fit line, and use the slope of your line to determine the microwave power of this particular oven. Assume that water's specific heat is independent of temperature (which is only approximately true; see Problem 73 ). $$\begin{array}{|l|c|c|c|c|c|c|c|} \hline \text { Time (s) } & 0 & 25 & 60 & 95 & 125 & 160 & 190 \\ \hline \text { Temperature ('C) } & 12 & 20 & 39 & 53 & 64 & 83 & 93 \\ \hline \end{array}$$

Why do large bodies of water exert a temperature-moderating effect on their surroundings?

since Earth is exposed to solar radiation, why doesn't Earth have the same temperature as the Sun?
