What is an example of chemical heat?
A fire is an example of chemical heat. The reaction of oxygen with combustible materials, simplest case, carbon say in coal, gives carbon dioxide and heat.
Does all heat radiated by the sun enters the atmosphere?
No. The sun radiates heat in all directions on 3 axes. The spherical arc of that which reaches the Earth's Atmosphere is very small in comparison.
What traps the heat in the atmosphere of a planet that causes it to heat up?
The Greenhouse effect...
What is the trapping of the heat by the atmosphere?
greenhouse effect
Why does the earth remain warm after sunset?
The surface of the earth holds heat, and the greenhouse gases in the atmosphere hold heat all through the night. If the earth had no atmosphere, then at night all the heat would escape out to space and the earth would be freezing.
Is it possible to construct a heat engine that will not expel heat into the atmosphere?
is it possible to construt a heat engine that will not expel heat into the atmosphere
What is the purpose of an engine block in the context of a car?
An engine block is used in cars to support the components of an engine. It is also used to transfer heat from friction to the atmosphere and engine coolant.
Why heat absorbed by the engine must be discharged?
Why does heat get absorbed by the engine must be discharged??The reason why heat is absorbed by the engine must be discharged to the atmosphere in one way or another because the engine will become overheated and eventually seize up and this is why a cooling system is built into the engine to cool it and prevent overheating.This is answered by J.G.NThank you for using this answer in what ever you need it for.
Does good radiators gain or lose heat easily?
Yes to both--they gain heat from the source, and lose heat to the atmosphere. They have to be able to do both; if the radiator in your car couldn't absorb heat from the coolant, it wouldn't cool the engine properly.
What is earth's external heat engine?
Earth's external heat engine is the planet's climate system, driven primarily by solar energy. The sun's rays heat the Earth's surface, causing air and water to move around in the atmosphere and oceans, creating weather patterns and climate variability. This heat engine plays a crucial role in regulating the planet's temperature and supporting life.
What is the difference between carnot heat engine and a heat engine?
difference schematic diagram between carnot heat engine and heat engine
How much energy does a car engine have?
A car engine is technically a heat engine that has no energy of its own but it converts the chemical energy in the fuels into heat and then into kinetic energy by turning a rotating shaft. The chemicals that react to make the engine work consists of carbon and hydrogen from the gasoline in the fuel tank, and oxygen taken from the atmosphere. The carbon reacts with oxygen to produce carbon dioxide and heat, while the hydrogen reacts with oxygen to produce water and heat.
What if a car runs without a coolant?
iIt will overheat and the engine will eventually lock up. The heat will do damage to the engine. How much is hard to say.
What part of the sun produces the majority of heat and light?
The core of the sun is where nuclear fusion occurs, producing the majority of the sun's heat and light. This fusion process converts hydrogen into helium, releasing energy in the form of heat and light.
The combustion reactions inside the engine of a rocket cause a buildup of heat and pressure. When this heat and pressure escapes into the atmosphere what force is created?
Thrust (apex)
How does heat enter the atmosphere?
Heat enters the Earth's atmosphere primarily through the absorption of sunlight by the Earth's surface, which warms up and then radiates heat back into the atmosphere. Other sources of heat entering the atmosphere include human activities such as burning fossil fuels and deforestation, which release heat-trapping greenhouse gases.
Why does the earth not lose its heat as quickly at night as the moon does?
The Earth retains heat better due to its thicker atmosphere and higher heat capacity compared to the moon. The atmosphere acts as a barrier, trapping heat on Earth, while the moon has no atmosphere to retain heat, causing rapid heat loss at night.
