Answer:
See explanation for details
Explanation:
6) C is false. What is going on there is actually a transformation of mechanical energy to the chemical energy stored in carbon dioxide in the atmosphere. The burning of the fossil fuel produces mechanical energy which is stored in the chemical bonds of CO2 hence the statement is false
7) A is true. Solar energy refers to energy from the sun, this energy is trapped from Tue sun and stored in chemical bonds in glucose, and starch molecules during photosynthesis.
8) C represents the release of carbon dioxide by the burning of fossil fuels.
9) B,C,D, E
B refers to photosynthesis in which plants take in atmospheric carbon dioxide
C refers to the burning of fossil rules which releases atmospheric carbon dioxide
D refers to the dissolution of atmospheric carbon dioxide in water bodies to form carbonates in water.
E refers refers the return of organic carbon to the soil by dead organisms
10) A and C
A shows the conversion of solar energy to chemical energy
C shows the conversion of mechanical energy to chemical energy
An atom cannot be broken down any smaller whereas a compound is made up of atoms and can be broken down into smaller pieces (the individual atoms that make it up)
Hope this helps!
Answer:
<em>The valid conclusion is:</em>
- <u><em>D. the temperature of the object is increasing, while the temperature of the water is decreasing</em></u>
<u><em></em></u>
Explanation:
The answer choices are:
- <em>A. the temperature of the object is decreasing, while the temperature of the water is increasing</em>
- <em>B. the temperature of the object is decreasing, while the temperature of the water is decreasing</em>
- <em>C. the temperature of the object is increasing, while the temperature of the water is increasing</em>
- <em>D. the temperature of the object is increasing, while the temperature of the water is decreasing</em>

<h2>Solution</h2>
<em />
Thermal or heat energy always flows from the hotter substances to the cooler substances.
Thus, since the arrows show that the thermal energy is flowing from the water to the object, the water is losing thermal energy and the object is gaining thermal energy.
When an object gains thermal energy, and there is not involved a change of phase, the temperature of the object increases. Thus, the temperature of the object is increasing.
On the other hand, since water is losing thermal energy, and there is not involved a change of phase, the temperature of the water decreases.
Therefore, the correct conclusion is described by the option A:
- <em>A. the temperature of the object is decreasing, while the temperature of the water is increasing</em>
Answer:
Surely with water
Ok, but how?
There are many Hydrogen Bond between H2O moleculs and london bonds. When fishes take water with their gill,they are broke london bonds. And they can take their needs, Oxygen. Only this.
Good luck :D
