When water vapor condenses during the formation of clouds, energy is released into the atmosphere through the process of latent heating.

Huge amounts of solar energy are absorbed during the evaporation process. There is no thermal equilibrium in protostars. They emit radiation that causes them to lose energy, but their interior temperatures aren't hot enough to start nuclear fusion to replenish the energy. They consequently tighten and warm up. Fusion can replace the energy they are losing once they are heated enough on the inside (about 107 K). The gas atoms start to collide more and get closer together as the cloud gets smaller, which warms them up. The cloud keeps shrinking and heating up until the force of gravity is balanced by the pressure from the heat.

bearhunter [10]

Answer:

10⁻¹² W / m²

Explanation:

The feeble sound that a man can hear is of the vale which measures 0 on decibel scale . The intensity of sound in terms of J / m² .s is 10⁻¹² W / m² .

So the intensity of sound of monkey at 2.5 km must be 10⁻¹² W / m² .

What disperses seeds?
elena-14-01-66 [18.8K]
The answer would be :People, animals, water & the wind.
The reason as to why these would be the answer is because the wind disperses seeds by blowing them through the air to different locations. The water washes the seed away to a location away from the parent. Animals disperse seeds, when they leave behind their waste and the seeds are in the waste. Lastly people disperse seeds in many ways, but one of them would be like throwing them into the grass, and ir planting them.

In addition to light and chlorophyll photosynthesis requires
labwork [276]

Answer:

Water (H₂O) and Carbon dioxide (CO₂)

Explanation:

Photosynthesis usually refers to the process by which the green plants can synthesize their own food in the presence of sunlight, water, carbon dioxide, and light. This process helps in the conversion of light energy into chemical energy.

In addition to the sunlight and chlorophyll, the process of photosynthesis requires water as well as carbon dioxide. The plants are comprised of green pigments on their leaves that are commonly known as chlorophyll. These pigments absorb the water molecules and carbon dioxide gas that helps in synthesizing their food.

The equation for the process of photosynthesis is given below:

6CO₂ + 6H₂0 + (energy) → C₆H₁₂O₆ + 6O₂
