The atmosphere is heated chiefly by radiation emitted by Earth?
This statement is incorrect. The atmosphere is heated primarily by the sun's radiation that enters the Earth's atmosphere. Some of this solar radiation is absorbed by the Earth's surface and then re-radiated as infrared radiation, which is partially trapped by greenhouse gases in the atmosphere, causing warming. This process is known as the greenhouse effect.
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.
Is the earths atmosphere heated by solar energy?
Yes, the Earth's atmosphere is heated by solar energy. Sunlight penetrates the atmosphere and warms the surface of the Earth. This heat is then radiated back into the atmosphere, contributing to its overall temperature.
What is the role of the sun to the different planets?
The sun plays a central role in the solar system by providing light and heat to the planets through radiation. It is responsible for maintaining the orbits of the planets through its gravitational pull. Additionally, the sun is the primary source of energy for many processes on the planets, such as photosynthesis on Earth.
Which process is primarily responsible for the transfer of energy by air currents within the Earth's atmosphere?
Convection is the primary process responsible for the transfer of energy by air currents within the Earth's atmosphere. As air near the surface is heated, it becomes less dense and rises, creating air currents that transfer heat energy vertically in the atmosphere. This convection process plays a significant role in redistributing heat around the globe.
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.
What happens when a liquid is heated-?
When a liquid is heated, the kinetic energy of its particles increases, causing them to move faster and farther apart. This results in the liquid expanding and eventually reaching its boiling point, at which it changes into a gas.
How is water heated?
by boling it it turns hot and becomes heated
How is earth's surface heated by the sun?
The Earth's surface is heated by the sun through a process called solar radiation. Sunlight, which consists of energy in the form of electromagnetic waves, reaches the Earth and heats up its surface when it is absorbed by land, water, and other surfaces. This energy is then retained and warms the Earth's surface.
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.
What are some changes that may occur when a solid is heated by the sun?
When a solid is heated by the sun, it may expand due to increased kinetic energy within its molecules, causing it to potentially change shape or size. The solid may also change its physical state and transition into a liquid or even a gas if the temperature reaches its melting or boiling point. Additionally, heating can alter the color or texture of the solid as its chemical composition may be affected by the heat.
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.
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
Why metal spoon is heated at one end and the heat is felt at the other and after a while?
The heat is transferred along the metal spoon through a process known as conduction. When one end of the spoon is heated, the particles at that end gain energy and vibrate, transferring heat energy to neighboring particles. This vibration and transfer of energy continues along the length of the spoon until the other end also becomes heated.
