The atmosphere is heated chiefly by radiation emitted by Earth?
The atmosphere is heated chiefly by radiation from Earth's surface rather than by direct solar radiation because about 50 percent of the solar energy is absorbed at Earth's surface. 30 percent is reflected back to space. 20 percent is absorbed by clouds and the atmosphere's gases.
What is the role of the sun to the different planets?
Within the Sun, nuclear fusion between hydrogen and helium takes place, giving off enormous amounts of energy. This energy is released in the form of radiation, which travels through the vacuum of space and reaches planets.
Is the earths atmosphere heated by solar energy?
yes
Why do hot air balloons float in the ar?
As the air in the balloon is heated, it expands and becomes less dense, or that is, becomes lighter. This then provides lift to the balloon and the basket. The reason the air in the balloon expands, is because as it is heated, the molecules of air move faster and spread out to fill the entire volume of the balloon.
How does the convection zone work on the sun?
The convection zone is how the energy from the core is transported to the photosphere. The plasma is heated, rises to near the surface, cools and then falls back toward the core to be heated again.
What happens when a liquid is heated-?
The kinetic energy content increases and the speed of its particles increases.
What energy transformation takes place in an engine?
In steam and combustion engines, thermal energy is changed to mechanical energy. Either heated gas or heated fluid is created that exerts force to turn the engine. In combustion engines, chemical energy becomes thermal energy which becomes mechanical energy. In electrical engines (motors), electrical energy is changed to mechanical energy by the manipulation of magnetic fields.
When a solid gains heat energy its molecules begin vibrating too quickly to stay together so the solid becomes an?
it becomes a liquid, and then a gas after that if heated even more.
How is water heated?
by boling it it turns hot and becomes heated
What happens to the density of a fluid when it is heated?
When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules. When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules.
When a solid gains heat energy it's molecules begin vibrating too quickly to stay together so the solid becomes a?
it becomes a liquid, and then a gas after that if heated even more.
What happens when rock heated?
When rock is heated it becomes enlarged. If the rock becomes too hot from the heat it will break and crack.
When matter is heated does it contract?
No, when matter becomes heated it always expands, meanwhile when matter becomes cool it always contracts.
Process of water turning into vapour?
Water most often becomes vapor when it is heated up. As water is heated up, its molecules vibrate faster. When water reaches its boiling point, the molecules are unable to remain a liquid and transition into a gas.
When a gas is heated is all of the absorbed energy converted to kinetic energy or potential?
When a gas is heated the energy is converted to kinetic energy.
How does the particles of a liquid behave when heated?
When a liquid is heated, the particles gain energy and begin to move more rapidly. This increased kinetic energy causes the particles to move farther apart and slide past one another more easily. As a result, the liquid expands and becomes less dense.
What does water do as it is heated?
it will boil once it reaches 100 degrees Celsius
