How does the law of conservation of energy relate to the processes going on in the water and in the plants?

Answers

Answer 1

Answer:

Answer: Matter is not destroyed, only changes forms.

Explanation: Take my answer with a grain of salt, I'm not a genius in this type of stuff but, the law of matter states that matter is not destroyed, only changes forms. This can be applied to photosynthesis because the plants take water and use it to make glucose to eat.

Again, I'm not genius so take my answer with a grain of salt but, hope it at least helps a little.

Answer 2

Answer: The law of conservation of energy is a fundamental principle in physics that states that energy cannot be created or destroyed in an isolated system; it can only change forms or be transferred from one part of the system to another. This law applies to various natural processes, including those occurring in water and plants. Here's how it relates to these processes:

1. Photosynthesis in Plants:
- Plants undergo photosynthesis, a process in which they convert light energy from the sun into chemical energy stored in the form of glucose (a sugar) and other organic molecules.
- The law of conservation of energy applies here because the energy in sunlight is transformed into chemical energy within the plant. This chemical energy can be stored and later used for various plant functions.
- Photosynthesis also involves the conversion of carbon dioxide and water into glucose and oxygen, but the total energy within the system remains constant, following the law of conservation of energy.

2. Water in the Hydrologic Cycle:
- The hydrologic cycle involves the movement of water between various reservoirs on Earth, including oceans, land, and the atmosphere.
- Water evaporates from the surface (e.g., from oceans, lakes, and rivers) into the atmosphere due to the input of energy, primarily from the sun. This energy causes water molecules to change from a liquid to a gaseous state.
- When the water vapor condenses in the atmosphere, it releases heat energy (latent heat), warming the surrounding air. This energy is then transferred to the surrounding environment.
- Eventually, the condensed water falls back to the surface as precipitation, releasing the stored energy in the form of heat.

In both of these natural processes, the law of conservation of energy is upheld. Energy is transformed and transferred, but the total energy within the system remains constant.

A sample of a substance has these characteristics:• melting point or 9811 K
• hard. brittle solid at room temperature
• poor conductor of heat and electricity as a solid
• good conductor of electricity as a liquid or in an aqueous solution
This sample is classified as
(1) a metallic element
(2) a radioactive element
(3) a molecular compound
(4) an ionic compound

Answers

Those characteristic belong to an ionic compountd. Ionic compounds have strong bonds between their atoms (ionic bond is the strongest molecular bond) which conferes this kind of compounds high melting point, wich 9811 K is. Ionic compounds do not transmit current, because they do not have free electrons, like metals do, then they are poor conductors as solid. Ionic compounds dissolve in water into ions which are charges that can move, becoming then good conductors. The structure of ionic compound is a net of cristals which make them hard and brittle. Then, the answer i s option (4) an ionic compound.

Answer:

an ionic compound

Explanation:

How many moles are in 15 grams of carbon dioxide?

Answers

Answer:

There are 0.34 moles of CO2 in 15 grams of CO2

Explanation:

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 mole CO2.

Molar mass of CO2 = Molar mass of Carbon + Molar mass of Oxygen multiplied by 2

Molar mass of carbon = 12 g/mol

Molar mass of oxygen= 16g/mol

Molar mass of CO2= 12g/mol + (16g/mol)2

= 12g/mol +32g/mol= 44g/mol

In other words, we can say that 1 mole of CO2 has a mass of 44gram

Number of moles of CO2 = mass of CO2 / molar mass of CO2

Mass of CO2= 15g/mol

Number of moles of CO2= 15gmol-1 / 44gmol-1

= 0.3409 moles

Hence, there are 0.34moles of CO2 present in 15 grams of CO2.

Answer: 0.34 moles

A ten mile area of trees is removed from the tropical rainforest. How will this affect the amount of water and the amount of oxygen in the area?

Answers

We know that the roots of the trees would absorb the water under the ground. This is necessary for photosynthesis. Photosynthesis would produce food for the tree and as by product, oxygen is produced. Removing the tree would decrease the water consumption but would also decrease the oxygen production.

Removing the tree would decrease the water consumption but would also decrease the oxygen production.

What is a tropical rainforest?

Tropical rainforests are found in Central and South America, western and central Africa, western India, Southeast Asia, the island of New Guinea, and Australia.

Sunlight strikes the tropics almost straight on, producing intense solar energy that keeps temperatures high, between 21° and 30°C (70° and 85°F).

Deforestation has an adverse affect on air by reducing the amount of oxygen and increasing the amount of carbon dioxide as well as contributing to global warming.
