Las Vegas, Nevada is in a desert. How does its rapid population growth affect the
Scrat [10]

Answer:

Many areas of the United States experience explosive population growth. <u>The more people that reside someplace, the more demand there is for water there.</u> Often these urban-growth <u>expansions are unplanned and place extraordinary stress on the water supply system, mainly on the groundwater.</u> <u>The stress often depletes groundwater supply, thereby causing wells to dry up.</u> Then water must be brought from somewhere else to support the local population.

Such situations have occurred all over the United States. For example, increased population growth in the southwestern United States has significantly lowered the water table 50 to 200 feet (depending on the area) since the 1940s. Managing urban growth, efforts to reduce water demand, conservation of the resource, and attempts to increase the water supply all address the problem of exceeding water resource limits.

<u>Human activities affect groundwater quality.</u>

<u>Here are some sources </u>and possible solutions to groundwater pollution:

<u>Agriculture</u>—Reduce usage of pesticides and fertilizers.

<u>Landfills</u>—Monitor for leakage and repair linings.

<u>Underground storage tanks</u>—Remove damaged and unused tanks.

<u>Household wastes</u>—Properly dispose of household hazardous waste.

<u>Septic tank leaks</u>—Properly maintain and repair tanks.

Igoryamba

The heat will flow from Cu to Fe because Cu has higher temperature and has lower peak value .

Given ,

two aircraft rivets , one iron and the other copper , are placed in a calorimeter .

the initial temp of the calorimeter is 20 degC .

mass of iron = 30 g

initial temp of iron = 0 degC

Mass of copper = 20 g

initial temp of copper = 100 degC

Here copper has higher temp ,thus heat flow from Cu to Fe .

<h3>What is heat flow ?</h3>

Heat flow is the movement of heat from higher temperature to lower temperature .

<h3>What is calorimeter ?</h3>

It is an object used for measuring the heat flow , heat capacity of a chemical reaction as well as the physical changes .
