h. water vapor condensing on the metal
i.the metal oxidizes, becoming dull and brittle
j.salt being dissolved by water
Answer:
corrosion of aluminum metal by hydrochloric acid - chemical change
melting wax - physical change
pulverizing an aspirin tablet - physical change
digesting a Three Musketeersbar - chemical change
explosion of nitroglycerin - chemical change
a burning match - chemical change
metal warming up, due to the burning match - physical change
water vapor condensing on the metal - physical change
the metal oxidizes, becoming dull and brittle - chemical change
salt being dissolved by water - physical change
Explanation:
A chemical change is one in which a new substance is produced and it is not easily reversible. A chemical change always goes with absorption or evolution of heat.
On the other hand, a physical change is one in which no new substance is formed and it is easily reversible.
The processes mentioned in the question were classified into physical and chemical changes as we can see in the answer section.

When your tire blows out in the middle of a drive, you should A. let go of the steering wheel B. pump the brakes immediately C. grip the steering wheel firmly D. immediately steer to the side of the road
Answer:
c) grip the steering wheel firmly
Explanation:
A) does not make sense because if you let the steering wheel go, you will loose complete control over the vehicle. DON'T DO THIS!
B) Pumping the brakes immediately is NOT recommended in this situation. Articles show that you should if anything accelerate slightly (if needed) to keep the car's momentum until you have gained enough control of the vehicle to where you are able to pull off to the shoulder.
D) Allow yourself the time to get the car under control before immediately pulling off to the shoulder. Depending on which side the tire blew, the car will naturally steer that direction. Pull the steering wheel the opposite direction the car's tire is pulling.

What are the differences between architects and engineers? in box
Answer:
Both are professional titles acquired through specific schooling and a licensing process.
With regards to the building industry, an architect is the generalist and an engineer is the specialist. Generally, the architect is the conceptual designer of the project, involved through all stages of a project. Engineers come and go (some stay significantly longer than others) and focus on a specific aspect of a building such as the mechanical systems or the structure. Architects and engineers together make up "the design team," and they work together to make the design complete. Architectural elements may be moved for the structure to make more sense and vice versa. The architect is usually the overseer, communicating with all the disciplines involved. The architect is likely the first to notice that the proposed ductwork conflicts with a structural beam, for example.
If the project is large enough, you might have two sets of architect teams: the design architect and the executive architect, also known as the Architect of Record. The executive architect has a more technical focus.
The technical aspects of architecture include compliance with building codes and figuring out all the building stuff related to the final product. For example, a plumbing engineer's drawing will have a line on a drawing representing a plumbing line. An architect's drawing might include a detail that shows that plumbing line as an actual pipe with a thickness with the bricks and cement block of the wall it is penetrating as well as whatever seal will be keeping the rain out.
Because of the difference in role and scope between an architect and engineer, the engineer of a project will be working on many other projects simultaneously, while the architect is dedicated to a few or just the one.

Which evils of modern society does Mr. Diamond cite as evidence that the Neolithic Revolution was a negative event in the history of mankind?
The evils of modern society referred to by Jared Diamond in his article "The Worst Mistake in the History of the Human Race" are:
Population GrowthHealth IssuesGross social and sexual inequalityDespotismIn his article, he describes the above challenges as a fall out of the Neolithic Revolution. The Neolithic Revolution is none other than the discovery of Agriculture by man.
His article visits evidence upon evidence using evolution, and findings from archeology to buttress his points.
1. Population Growth: His interpretation of this is that because man discovered agriculture, he shelved his nomadic lifestyle (hunting and gathering) in favor of sedentary existence. Because man no longer migrated from place to place, population density triggered around the location where he chose to settle.
2. James cites the following as evidence that agriculture created an upward trajectory in the occurrence of health issues:
first, while the nomadic man (hunter and gatherer) had and ate a variety of foods the sedentary (agriculturer) was limited to just a few carbohydrates (starch) based crops. Of course, this is an approximation but the point is very clear and near to the truth. second, increases in population densities leading to the spread of parasites and infectious diseases; third, the risk of death increased because of the dependence on just a few varieties of crops to propagate.3. James also posited that despotism and inequality are fallouts of Agriculture. Hunters and gathers, according to him, have no need to store food for prolonged periods of time. They depended on fresh intake of nutrients. Nature held the power of ownership of resources. Hence, there were no class divisions such as the rich and the poor, the weak and the powerful (politically speaking).
4. He also posited that under the nomadic culture, the job of the woman was mostly to transport babies as the tribes moved from one location to the other. Under the agricultural system, women became more like beasts of burden tasked with various kinds of agricultural routines including carrying very heavy loads from farm to sites of residence.

PLEASE HELP WILL MARK BRAINLIEST! 20 POINTS If the working-age population was 279 million of the 320 million people living in the United States and 122 million were employed while 14 million were unemployed, the unemployment rate would be approximately 11.5%. 10.2%. 5%. 4.8%. 10.29%.

Add 122 million and 14 million and you get 136 million. That is how many people are working and not working. Ignore the other information (279 million and 320 million) because those are misleading. Now do: 14/136 (leave out the millions) and you get 0.1029. Multiply by 100 and you get 10.29% or 10.2%.

Jack and Jill want to play Monopoly with us.
Which meaning of the word play is used in the sentence?
A noun meaning "an athletic activity"
A verb meaning "to take part in an activity such as a sport"
A noun meaning "an activity that is engaged in for recreation"
A verb meaning "to engage in an activity for recreation"
Answer:
A verb meaning "to engage in an activity for recreation"
Explanation:
#1 and #2 automatically wouldn't be the answers because the word 'play' isn't being used to describe a sport being played - monopoly is a board game, not a sport (lol). #3 wouldn't be the answer because the word 'play' isn't a noun, since it isn't being used as, or means a place, person, or thing.

Which job would not be best suited for an extroverted person?
Answer:
All job are equal.
but you ask.
the answer is labourer
but labour also important for making house.
Answer:
Office Job
Explanation:
Step 1: Define what an extroverted person is
According to https://www.healthline.com, it states that "extroverts are often described as happy, positive, cheerful, and sociable. They aren't as likely to dwell on problems or ponder difficulties. While they experience difficulties and troubles like anyone else, extroverts are often more able to let it roll off their backs."
Step 2: Examine what would not be the best suited job for an extrovert
Since extroverts are often sociable, which means they are outgoing and like doing stuff with other people, this means that they will most likely not want an office job. Office jobs are often isolated for most of the day which is something an extrovert wouldn't want. Therefore, I think that an Office Job is the least suited for an extroverted person.
