how does electrons behave in a mineral with metallic bonding? The atoms that the electrons leave behind become positive ions, and the interaction between such ions and valence electrons gives rise to the cohesive or binding force that holds the metallic crystal together.
What happens to smoke in vacuum? A spaceship orbiting earth is moving fast enough to break gravity and the vacuum of space has no density. In this case the smoke may expand in all directions, or the direction of force applied by an explosion and continue moving at the same direction and velocity of the object that created the ‘burn’ process.
Does smoke rise in space? A fire in space is different than a fire on Earth. In microgravity, flames don’t taper like they do on your dinner table: They stay blobby and spherical. And without natural convection, flames spread differently, too—instead of rising, they just follow the spacecraft’s ventilation system.
Why is smoke anti gravity? Smoke is released by fire into heated air. The heated air is thinner than the surrounding air, so the pull of gravity on the hot air isn’t as strong as it is on the colder, denser air. The smoke is not “defying” gravity; it is just gravity acting less strongly on thinner air masses.

how a doctor should behave?
“Physicians should be personable, great listeners, and empathetic to the concerns of their patients,” he elaborates. “They should not be condescending or arrogant. They should treat others as they want to be treated.” “Physicians should be personable, great listeners, and empathetic to the concerns of their patients.”
how to behave when meeting your in laws?
To help you navigate meeting the in-laws, we asked top relationship experts how to score a rave review.
what conditions do real gases behave ideally?
Systems with either very low pressures or high temperatures enable real gases to be estimated as “ideal.” The low pressure of a system allows the gas particles to experience less intermolecular forces with other gas particles.
how a ceo should behave?
Findings from a database of 17,000 C-suite assessments reveal that successful CEOs demonstrate four specific behaviors that prove critical to their performance: They’re decisive, they engage for impact, they adapt proactively, and they deliver reliably.
what makes an element behave as a metal?
Metals are primarily defined by a number of their special properties, great conduction of electricity and heat as well as malleability, and the ability to strongly reflect light.
how do tawny owls behave?
Tawny Frogmouths sleep during the day, often camoflaged among tree branches. At dusk they shake their disguise and begin their nocturnal hunt. They catch prey in flight, or by sitting motionless in a tree and then swooping down on ground-dwelling prey.
Do bungee cords have a spring constant?
A bungee cord is essentially a very long rubber band that can stretch up to four times its unstretched length. However, its spring constant varies over its stretch [see Menz, P.G.
How do we behave with animals?
Act friendly, calm and consequent in company with animals. Turn and walk calmly away from any animal that behaves in a way you do not feel comfortable with. Animals with feathers normally dislike to be pet. Animals with fur normally like to be cuddled and scratched.
How can a first generation immigrant be used?
The U.S. government generally accepts the definition that the first member of a family to acquire citizenship or permanent resident status qualifies as the family’s first generation, but the Census Bureau defines only foreign-born individuals as first generation.
Do cockapoos ever calm down?
Most Cockapoo dogs will begin slowing down at between one and two years of age. (But not ALL become relaxed…) By the time they are around three years old or so, Cockapoos will be much calmer; however, even adult dogs will need quite a bit of exercise in order to burn off their excess energy.
Why do real gases behave more ideally at high temperature and low pressure?
Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles’ kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.
How does rennet cause curd formation?
Rennet allows cheesemakers to efficiently turn fresh milk into curd, a technique they’ve been using for thousands of years. Over time, milk curds on its own, but by that time, the milk may sour. Rennet speeds up this process so proteins in the milk form curd, and the liquid separates and run off as whey.
What element is most like nitrogen?
nitrogen group element, any of the chemical elements that constitute Group 15 (Va) of the periodic table. The group consists of nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), and moscovium (Mc).
What is special about a tawny owl?
Tawny owls are famous for the fierce defence of their young: bird ringers usually wear crash helmets with visors to protect themselves when ringing baby tawnies. Tawnies are specially adapted for hunting in woodland, for their short wings give them great manoeuvrability.
What makes an element a metal?
In chemistry, a metal is an element that readily forms positive ions (cations) and has metallic bonds. Metals are sometimes described as a lattice of positive ions surrounded by a cloud of delocalized electrons.
How do bungee cords function?
Today, bungee cords are most often used to secure objects without tying knots and to absorb shock. Inexpensive bungee cords, with metal or plastic hooks on each end, are marketed as a general utility item.
What did King George III say?
In his address, the king spoke about the signing of the U.S. Declaration of Independence and the revolutionary leaders who signed it, saying, “for daring and desperate is the spirit of those leaders, whose object has always been dominion and power, that they have now openly renounced all allegiance to the crown, and …
What elements does nitrogen like to bond with?
At room temperature, nitrogen is a very inactive gas. It does not combine with oxygen, hydrogen, or most other elements. Nitrogen will combine with oxygen, however, in the presence of lightning or a spark.
What happens to unlike electric charges?
Like charges repel each other, and unlike charges attract each other. Thus, two positive charges repel each other, as do two negative charges.
How do you behave in a British pub Burgess Meredith?
A Welcome To Britain (retitled How To Behave In Britain) is a 1943 training film for the United States Armed Forces which was narrated (and co-written and co-directed) by Burgess Meredith and Anthony Asquith.
Does climate affect stomata number?
Because temperature was shown to be a better predictor of stomatal density and gwmax than latitude, we suggest that temperature is likely to be an important driver of stomatal characters in this species.
How does the body react to a vacuum?
Contrary to how the lungs are supposed to function at atmospheric pressure, oxygen diffuses out of the bloodstream when the lungs are exposed to a vacuum. This leads to a condition called hypoxia, or oxygen deprivation.
