no it cant be chaNGED
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.
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 the physical state of matter is a physical change.
this is a physical 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.
doldrum
Doldrum
Not much just the same old boring stuff.
Origin: 1795-1805; obsolete word "Dold" meaning "Stupid".
Question: The doldrums happen in a zone known as the what? Answer: intertropical convergence zone
Because they are an area where wind lulls are common, where there is know wind, and can waste time when crossing the atlantic.
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 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.
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.
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.
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.
Humdrum = monotonous routine. She spent the day doing all the humdrum tasks that had to be done, cooking, washing, ironing and cleaning.
