Engineering (1999‚ Vol. 125‚ pp. 59–75) describes a study of the thermal inertia properties of autoclaved aerated concrete used as a building material. Five samples of the material were tested in a structure‚ and the average interior temperatures (°C) reported were as follows: 23.01‚ 22.22‚ 22.04‚ 22.62‚ and 22.59. a.

1. Explain the difference between a “reserve” and a “resource”. What factors influence estimates of reserves and resources for commodities such as minerals or fossil fuels? Resources and reserves are similar in that the both benefit humanity. Resources are materials that can be used to satisfy human needs‚ or used as support. Reserves on the other hand are known deposits with the ability to extract the available material economically; the size of these reserves is not always known or defined

1. Economics is the study of the choices that we make in the allocation of scarce resources. 2. In choosing whether or not to go to a particular concert ... if the marginal benefit (marginal utility) gained is greater than the marginal cost‚ then it would be “rational” to go. 3.
