the second law of thermodynamics states that?
Answer:
"As energy is transferred or transformed, more and more of it is wasted."
Explanation:
Answer:
"As energy is transferred or transformed, more and more of it is wasted."
In this case the second law of thermodynamics (in the simplified form presented here) says that no matter what process takes place inside the container, its entropy must increase or remain the same in the limit of a reversible process...
Explanation:
The second law of thermodynamics states that as energy is transferred or transformed, more and more of it is wasted. It's one of the four laws of thermodynamics, which describe the relationships between thermal energy, or heat, and other forms of energy, and how energy affects matter...
The second law of thermodynamics says that when energy changes from one form to another form, or matter moves freely, entropy (disorder) in a closed system increases. Differences in temperature, pressure, and density tend to even out horizontally after a while...
The second law of thermodynamics describes the nature of processes and chemical reactions as follows: processes occur spontaneously if and only if by their process, the entropy change in the universe, is greater than or equal to zero…
Second law of thermodynamics:Statement,examples and applications. The second law of thermodynamics states that heat can flow spontaneously from a hot object to a cold object; heat will not flow spontaneously from a cold object to a hot object. Carnot engine, heat engine are some examples of second law of thermodynamics .....
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.
Why is the second law of thermodynamics so important? Second law of thermodynamics is very important because it talks about entropy and as we have discussed, 'entropy dictates whether or not a process or a reaction is going to be spontaneous'...
His formulation of the second law, which was published in German in 1854, is known as the Clausius statement: Heat can never pass from a colder to a warmer body without some other change, connected therewith, occurring at the same time. The statement by Clausius uses the concept of 'passage of heat'...
“The first law of thermodynamics also known as the law of conservation of energy states that energy can neither be created nor destroyed, but it can be changed from one form to another.” “The second law of thermodynamics states that the entropy in an isolated system always increases.”

What is the relative humidity of a dry-bulb temperature of 15°C and wet-bulb temperature of 12°C
The relative humidity of a dry-bulb temperature of 15°C and a wet-bulb temperature of 12°C is 71%.
What do you mean by Relative Humidity?Relative humidity may be defined as the proportion of atmospheric moisture present compared to the amount that would be present if the air were permeated.
Relative humidity can be calculated by subtracting the temperature of the dry bulb from the temperature of the wet bulb.
After getting a specific value, refer to the relative humidity chart at the particular value of the dry-bulb temperature.
Therefore, the relative humidity of a dry-bulb temperature of 15°C and a wet-bulb temperature of 12°C is 71%.

state five qualities of good draught animals. State four precautions to be observed when using draught animals
Answer:
1. Conformation
Conformation refers to the form or shape of an animal. An animal with good conformation has a shape which shows the normal characteristics of its species and breed.
An animal used for draft must have a build well suited for pulling. It should be low to the ground, have powerful shoulders and legs, and have a broad frontal dimension that will accommodate the placement of a harness. It must be big enough to deliver, alone or in a pair, the power needed to pull equipment for an extended period of time. It must also be able to exert the concentrated or "instantaneous" effort needed to overcome temporary increases in the draft requirement caused by roots, rocks, hard soil, or inclines.
While some animals are bred to produce good draft abilities, within any breed individual animals vary greatly in these qualities, and care must be taken to choose those with the most potential. A thin but well-balanced animal can be strengthened with a good diet, health care, and work. However, an animal with a swayback, bad legs or impaired vision will be a constant source of trouble.
Selection is a process of matching ideal qualities against those seen or latent in a given animal. Good draft animals, regardless of species or breed, will have the following qualities:
• head well proportioned; squarish, sculptured look
• balanced vision and hearing; head carriage high and straight
• normal mouth; good teeth and jaw structure
• body should have depth and width; short, full neck, full shoulders, broad chest, and straight, broad beck
• wide, thick hindquarters, lowset and evenly-fleshed
• short legs, straight and square to the body; ample bone
• clean, well-developed joints; no swelling or unusual boniness; no turning in or out of knees or hoofs; free movement of limbs
• feet straight, hard; normal angulation of hoof.
Temperament
Temperament refers to the nature or disposition of an animal. Part of its temperament is determined genetically, both by breed and parentage; some of it is learned-a response to the treatment it receives from other animals or the people who raise and handle it.
Temperament is reflected in an animal's behavior, the way it moves and acts, and the way it reacts to the things around it. It is difficult to know much about temperament from the quick evaluation that usually precedes the purchase of a draft animal. The buyer must guess, from what is observable, whether or not an animal will accept new routines or maintenance and training, behave well in a pair, and prove to be a spirited yet steady-paced and manageable worker. Sometimes, what is observable is not typical of the animal's behavior. A basically lethargic bull, for example, may become very alert or nervous at the approach of a stranger, exhibiting a fierceness that could be misinterpreted as a strong yet controllable spirit. A donkey that is mishandled and mismanaged might kick or butt at its owner, or at any adult, but be led away quite easily by a child. The buyer must be aware of such possibilities and at the same time drew some basic conclusions about the animal's temperament.
The following are signs of good temperament:
• Good overall conformation and health. The animal has no physical handicaps that require it to compensate with aggressive or stubborn behavior. An animal with bad vision or hearing, an unsound leg or joint, or with a chronic respiratory or muscular weakness, protects itself by balking, spooking, shying, refusing to be harnessed or lying down during work. Its temperament is affected or shaped by its physical condition.
• The animal accepts the handling of the owner. The owner can pick up the animal's foot, open its mouth, lead it with a rope without having to use force or harsh measures.
• It does not shy or kick at other animals. The buyer should try to be present when it is being turned out with a herd or put into a corral with other animals. If an animal is unusually aggressive or cowardly, it may not work well in a pair. Aggressive animals force their work-mates to shy or lean out of the yoke or harness, while cowardly animals may refuse to step evenly with their mates, lagging behind.
When an animal is taken from its herd or original owner and staked out or corralled in a new place, it may experience shock. The animal may show signs of aggression, withdrawal, stubbornness, fear, or general anxiety. None of these reactions is unnatural during the adjustment period, and should not be taken as a sign of an unsuitable disposition. An animal's character becomes clear later, during training and preseason work. At that time the farmer can judge the ability of the animal to work as part of a pair or team. Buying an animal early in the offseason allows the owner time to seek a replacement should a problem arise.

Answer:
A: Cool, Dark Nebula
Explanation:
Before a star is born, the matter that will become the star exists as a interstellar gas and dust. The stars are formed as a result of the force of gravity compresses atoms in the interstellar gas.
