What is the difference between chemical change and physical change?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
Is toasted bread a physical change?
No. It's a chemical change because the process is irreversible, there is a change in colour and a change in odour.
A change in matter from one form to another is?
A change in the physical state of matter is a physical change.
Is decaying matter a physical or chemical change?
It's a chemical change. A chemical change is any change that causes a substance to change into another substance. A sign to know whether it's a chemical change or not, are the changes in odor. When something decays the change in smell is very powerful. Therefore, it is a chemical change.
When sandpaper smooths a piece of wood what kind of change is it?
this is a physical change
What Is air pressure at the equator?
doldrum
Which global wind would you find at 0 degrees?
Doldrum
What happens when you have doldrum?
Not much just the same old boring stuff.
Where does the word doldrum originate?
Origin: 1795-1805; obsolete word "Dold" meaning "Stupid".
Is the intertropical convergence zone as known as the doldrum?
Question: The doldrums happen in a zone known as the what? Answer: intertropical convergence zone
Why do the sailors avoid this doldrum?
Because they are an area where wind lulls are common, where there is know wind, and can waste time when crossing the atlantic.
Is a doldrum a high or low pressure zone?
A doldrum is a low-pressure zone, specifically referring to the Intertropical Convergence Zone (ITCZ) near the equator. In this area, the trade winds from both hemispheres converge, leading to calm winds and often resulting in stagnant weather conditions. This low-pressure region is characterized by warm, moist air that can produce thunderstorms and heavy rainfall.
What is doldrum belt?
The trade winds blow toward the equator from either side and diminish there to form a doldrum belt with an average width of between 200 and 300 miles. This belt is biased toward the Northern Hemisphere, being located between the equator and 7°N in February and between 5°N and 12°N in July at its greatest breadth. That breadth varies considerably, being widest on the eastern shores of the Atlantic and Pacific Oceans.
A sailing vessel is traveling along on an ocean voyage when it reaches a band of calm air that significantly curtails its movement The vessel is caught in?
a doldrum Sailors use the expressions " in irons " and " becalmed ", especially when the mighty sailing ships of yesteryear were in the Horse Latitudes of the Atlantic and Pacific. Everyday modern usage of the word " doldrum(s)" is used to describe a person(s) being in a depression or listless, lethargic, non-energetic, rather than to describe ships.
Are the doldrums found in the north pole?
For sailors, the doldrums are typically found in equatorial waters. The North Pole is covered with floating ice, so however calm and windless it may be -- which is rare, it is not a place where a sailor would use the word doldrum to describe the oceanic conditions.
How do doldrums affect the earths atmosphere?
The doldrums are generally the area around the equator. This is an area of light winds and rising warm moist air. a boundary north and south of these doldrums changes with the season and is called the doldrum trough. either side of the doldrum trough north or south of the equator are the trade winds. The doldrum is important in the exchange of warm air for the exchange of warm equatorial air with sinking cold polar air. Without the energy exchange the earth would grow colder in the north and south regions of the planet, and hotter in the tropical regions. The exchange process is more complex than you might imagine, because of the rotation of the earth, the location of land masses, the ocean currents with their temperatures and salinity and on and on.
Why are information systems important in business today?
Information systems play an important in business today. Without effective, vibrant and updated information system in force, the business will be in doldrum and will be sidelined in the long run due to stiff competition prevalent in each and every business now a days.
