Answer:

By calculating the mass and the reactant as the specific heat and temperature changes.

Explanation:

  • The entropy is one of the thermodynamic properties of the system where the internal and is added to the product and the refers to the capacity to non-mechanical work and capacity to the release of the heat.
  • And is expressed as the H → E + PV. and is the change of the internal energy and the plus the product of the constant.

Where do scientists fit into the process of making environmental laws?
4vir4ik [10]

hello there

Andrea's point is probably the answer you're looking for, however, you should keep in mind that many (most?) environmental laws are driven more by politics than by the available data. Scientists do research on any number of topics (environmental or not) that have implications for our society. We (scientists) like to think that policy makers take our data and results into consideration when drafting legislation, but I would say that in my experience this rarely happens. For one, there have rarely been any federal legislators who understand science. Even the few physicians who've gone into politics seem largely to fail to understand very basic tenets of science, or at least they don't often demonstrate it with their political actions. Leaving environmental issues, for example, if politicians took science into account, there would be no discussion in any school district in the country about whether or not evolution should be taught in schools, as there are simply *NO* scientists who are qualified to have an opinion who would suggest it shouldn't. Environmental issues are not really any different.

hope that helped bye

If a 30 °C air parcel rises from sea level to 3000 meters altitude and cools at the dry adiabatic rate, what will be its tempera
Dmitry [639]

Answer:

0^\circ C

Explanation:

Dry adiabatic lapse rate is defined as:

\Gamma = 9.8 ^\circ C/km

The air rises 3000 m, that is 3 km.

If it cools 9.8 ^\circ C each km its temperature drops approximately 30 ^\circ C. From 30 to 0.

Many times a map scale will show distances in both miles and
fiasKO [112]

The correct answer is - kilometers.

Very often, the map scale is showing distances in both miles and kilometers. The reason for this that the majority of the countries in the world use the metric system, thus the kilometers are a must, but also there countries that do not use this system, thus they include the miles. In this way, the map scale can be used by people that both use and not use the metric system in their daily lives.

The map scale is a very important element on the maps. Its purpose is to enable the reader of the map to be able to measure the distance from one place to another, thus to be aware of the real distance in the real space.

18. All of the following represent examples of the incidence of tax, EXCEPT for *
emmasim [6.3K]

Answer: See explanation

Explanation:

You didn't give the options and I couldn't find the exact question online. Let me try help out.

Incidence of tax is the impact that a tax simply has on how the economic welfare are being distributed. It refers to how tax is being distributed between the producers and the buyers of a particular good. It should be noted that the tax burden is shared by the sellers depending on the elasticity of the said product.

For example, in a situation whereby a $2 tax is imposed on each good a producer produces, if the producer then pass the tax to the final consumers when he raised the price of the goods by $2, we can simply say that such good has a price inelastic as the entire burden falls on the consumer.

Also, assuming the producer can't increase prices because such good is price elastic, that is, there will be a greater change in the quantity of the goods demanded, the burden will be felt by the producer alone. Here, we can say that the tax incidence falls on the producer.
