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

Answers

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.

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.

Which of these natural resources is non renewable Sugarcane
Oil or petroleum
Corn
Sunlight

Answers

The second one: Oil or petroleum

Answer:

petroleum

Explanation:

Renewable energy is energy that is produced from sources that do not diminish or can be replenished within a human's life time. The most common examples apart from sunlight include wind, solar, geothermal, biomass, and hydropower, while non renewable energy is energy that can be produced from sources which deplete or cannot be replenished

How are chemical changes of matter related to the organization of the periodic table

Answers

Chemical changes of matter are related to electronic configuration which is same along a group in case of valence shell in the periodic table.

What is periodic table?

Periodic table is a tabular arrangement of elements in the form of a table. In the periodic table, elements are arranged according to the modern periodic law which states that the properties of elements are a periodic function of their atomic numbers.

It is called as periodic because properties repeat after regular intervals of atomic numbers . It is a tabular arrangement consisting of seven horizontal rows called periods and eighteen vertical columns called groups.

Elements present in the same group have same number of valence electrons and hence have similar properties while elements present in the same period show gradual variation in properties due to addition of one electron for each successive element in a period.
