Answer:
Specific heat is Jg−oK . So, a high value means that it takes MORE energy to raise (or lower) its temperature. ... Adding heat to a “low specific heat” compound will increase its temperature much more quickly than adding heat to a high specific heat compound.
Scientific questions and hypotheses come up frequently while one is engaged in investigating a scientific phenomenon such as natural geological phenomena as may occur in geological mapping in the field. For example, there may be a question does this canyon or deeply incised valley which is quite straight follow a weakness in the earth's crust like a major fault or the direction of bedding in well bedded sedimentary rocks. In a particular topographic area, some hypotheses which may be developed is that valleys follow geological structure whereas ridges follow resistant rocks like quartzites or quartz sandstones or in the ocean, points or capes may represent resistant quartz sandstones and bays may represent weak soft shales recessively weathering
The correct answer is; Water flowing downstream is held up in a reservoir behind a dam. Some water moves down channels through turbines connected to generators which produce electricity.
Further Explanation:
Hydroelectric power is being used more in recent times than in the past. Hydroelectric power is a more cleaner energy source than the coal plants that produce electricity.
Hydroelectric power plants are built within a dam system and uses the water as source of energy. The water goes into channels created that hits the turbines, the turbines are then moved around by the water and these are connected to the large generators and this produces electric. There are many new hydroelectric plants being built. One of the newest hydroelectric power plants is located in Pella, Iowa.

Answer: Also known as ‘blue nitro’. (Hope it’s right!)
Answer:
Explanation:
Hello there!
In this case, for this calorimetry problem, we can notice that the heat evolved by the hot tin is gained by the cold water as the calorimeter is perfectly isolated, so we can write:
Thus, by defining the heats in terms of mass, specific heat and temperatures, we get:
Now, since we are asked for the specific heat of tin, we solve for it as shown below:
Thus, when we plug in, we obtain:
