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.

In which sample of water do the water particles have more energy : 5grams of ice cubes at -10 C, or 5 g of liquid water at 20 C? How do you know?

Answers

Answer: 5 grams of liquid water at 20°C will have more energy.

Explanation:

Kinetic energy is the measure of temperature of the system.

The equation used to calculate kinetic energy of a particle follows:

$E=(3)/(2)kT$

where,

E = kinetic energy of the particles

k = Boltzmann constant = $1.38* 10^(-23)J/K$

T = temperature of the particle

From the above relation, it is visible that kinetic energy is directly related to the temperature of the system.

If the temperature of the particles is high, it means that the particles will have more energy.

We are given:

5 grams of ice cubes at -10°C

5 grams of liquid water at 20°C

So, the temperature of water particles is more than the temperature of ice cube.

Hence, 5 grams of liquid water at 20°C will have more energy.

5 g of liquid water at 20 C because liquids have a higher kinetic energyand the temperature is higher than that of the ice cubes

How does the chemical structure of a paper towel differ from the potatoes?

Answers

When you pass around the side dishes at this year's Thanksgiving feast, here's one thing to be thankful for: you're eating mashed potatoes instead of mashed paper towels. But if you were chewing on the towels instead of the spuds, would you even know it.

Because a Paper towel is made like a towel, it is manmade. Potatoes are natural things therefore different.

What is h20????????????????????

Answers

Water, one of the most vital elements for life on Earth, has the chemical formula $H_20$ . It is made up of one oxygen atom and two hydrogen atoms joined together covalently.

Due to its polar nature, water can establish hydrogen bonds with other molecules, giving it special features including high surface tension, cohesiveness, and thermal stability. It serves as a solvent, a medium for metabolic reactions, and a mechanism for controlling temperature, all of which are essential for diverse biological activities. Water is also essential to the functioning of Earth's ecosystems since it erodes the land and supports a variety of aquatic life. Water is essential for supporting all forms of life because of its quantity and adaptability.
