Answer:
The Earth's interior exhibits a change in trend in the "outer core."
Explanation:
<u>The 4 Main Layers of the Earth</u>
<em>1. Crust - </em>This is the outermost layer of the Earth. It consists of igneous, metamorphic and sedimentary rocks. This makes the crust rock solid.
<em>2. Mantle - </em>The mantle is formed by silicate rocks. It is located between the crust and the outer core. It consists of the upper mantle and the lower mantle. The upper mantle lies between the crust and the lower mantle while the lower mantle lies between the upper mantle and outer core.
<em>3. </em><em>Outer Core- </em>This is the only liquid layer of the earth. It is mostly made of iron and nickel. This causes a change in trend among all the other parts of the Earth which are solid.
<em>4. Inner Core- </em>This is the innermost part of the Earth. The temperature here is hotter than the sun. The solid inner core is said to be growing at the expense of the outer core. This also has the highest density of all.

Answer:
D. Water
Explanation:
Specific heat is defined as the amount of heat you need to add to a substance per unit of mass to increase its temperature in 1°C.
That means if you have the same mass of substances, the one with the higherst specific heat is the one that requires the most amount of heat to increase its temperature by one degree Celsius.
As you can see, water is the material with the highest specific heat doing the material that requires the most heat.
Right answer:
<h3>D. Water
</h3>
The alcohol has an oxygen atom single-bonded to hydrogen and single-bonded to a carbon-containing group.
<h3>What is alcohol? </h3>
Alcohol is defined as the organic compound which is derived from an hydrocarbon by replacing one hydrogen by hydroxyl group(—OH).
The general formula of alcohol is ROH.
where, R is the alkyl group.
The first member of alcohol is ethanol.
<h3>Physical properties of alcohol</h3>
- Alcohols are colourless.
- They give a sweet smell except for glycerol and few lower alcohols.
- They are flammable and produce a blue flame on burning.
- They don't produce any kind of smoke while burning.
- Alcohol are liquid at room temperature.
Thus, alcohol is an organic compound which contain an oxygen atom which is single-bonded to hydrogen and single-bonded to a carbon-containing group.
