The green house gases can be reduced up to a limit by eliminating the fossil fuels and chlorofluorocarbons. Fossil fuels are the major source of greenhouse gases.
<h3>What are green house gases?</h3>
Greenhouse gases are those which are capable of intense absorption of the temperature radiated from the earth's surface and make the earth atmosphere warm up.
Greenhouse gases are the main cause of global warming. Carbon dioxide, methane oxides of nitrogen and sulphur are the green house gases.
Fossil fuels are rich in hydrocarbons and they release these gases when burned. Mainly methane and other hydrocarbon gases intensely absorbs the temperature which is radiating away from the earth and thus the heat is trapped inside.
Therefore, by eliminating fossil fuels, greenhouse effect can be prevented.

Neptunes' average density is larger than that of Uranus. Hope this helps!
Answer:
Explanation:
We're starting a car. We have the fuel in the engine, and when the engine starts, that fuel is converted into power to move the car. The fuel is made of chemicals, right? Propane, gasoline, so on. What kind of energy comes from chemicals? <em>Chemical energy</em>, right?
That fuel is <em>chemical energy</em>, and the energy to move the car must be <em>kinetic/mechanical</em> energy. However, that's not the <em>only</em> source of <em>mechanical energy</em>.
There's another source of <em>mechanical energy</em> here as well: we have an electric battery. What kind of energy is found in a battery? The battery has electricity, and so it has <em>electrical energy</em>. Some of that <em>electrical energy</em> turns into <em>mechanical energy</em> when the car starts up.
But the engine heats up as well, right? There's one more energy that the <em>electrical energy</em> and <em>chemical energy</em> produce here: <em>thermal energy</em>. That's the source of the heat.
I hope this makes sense for you. Have a wonderful day!
Since the specific heat of silver is given to be 0.057 calories/gram*C, obtaining the amount of calories should be as easy as multiplying the specific heat by the given values of the weight and the temperature to do unit cancellation. This is shown below:
(<span>0.057 calories/gram*C</span>)(10 grams)(20 C) = 11.4 calories
