explain the question your asking
The correct answer to your question would be B) Loess, or <span>Aeolian deposits , reasoning to your question is because, loess is a german word but in english means loss or loose. So given that clay and small particles that are not combined together are loose particles. moves freely. Hope this helps you out.

Theses can include the power supply circuit a joule meter to measure the energy transferred which makes the calculations a lot easier.
A lit candle needs to draw oxygen from the air in order to continue burning. ... Thus, oxygen inside the glass jar will decrease and it gets filled with carbon dioxide, and eventually the candle's flame will Extinguish.
Answer: option <span>C. the total energy inside the calorimeter will decrease.
</span>
Justification:
The answer is a direct application of the first law of thermodynamic (the law of conservation of energy).
By telling that the t<span>he calorimeter is sealed so that there is no heat exchanged between the contents of the container and the surrounding air, the first law of thermodynamics implies that the total energy inside the calorimeter will not change.

<span>That statement, without adding any more is enough justification.

Regarding, the other statements, you can show they are true:
<span>A.
the thermometer will show an increase in temperature.
</span><span>
</span><span>
</span><span>Since the reaction is exothermic, the heat released will increase the temperature inside the sealed calorimeter,which, of course, is shown by the termometer.

</span><span>
</span><span>B. The potential
energy of the products will be lower than that of the reactants.
</span><span>
</span><span>
</span><span>In any exothermic reaction, the potential energy of the products is lower than that of the reactants, because the heat released is lost by the reactants when they react and transform into the products.
</span><span>
</span><span>
</span><span>D. The water
increases in temperature as the reaction gives off heat</span>.
Sure. The heat cannot leave the sealed calorimeter, but the water inside the calorimeter will absorb that heat: the molecules of water will gain kinetic energy and so its temperature will be increase.
