Is Jupiter hot or cold?

At an average distance of 484 million miles away from the sun, Jupiter does not receive much heat from it, and the planet generates most of its available heat energy from convection and the intense atmospheric pressures exerted on gases deep within the atmosphere. Near the core, liquid hydrogen is likely thousands of degrees F, but as altitude increases, the temperature drops rapidly.

How much does a gallon of water weigh?

Although an entire gallon of water weighs 8 pounds, a single molecule of water weighs 2.992 x 10^-23 grams. An entire mole of water is needed to weigh just 18 grams.\nSalt water weighs more than fresh water, and the variance depends on how salty the water is. Sea water is very salty. However, water becomes saline after only a thousandth of the weight of the water is salt.\nAnother type of water that is heavier than pure water is hard water. Hard water is a result of high levels of calcium and magnesium ions in the water. The addition of these ions in the water makes it less useful. Hard water ..

What is the difference betwen scalar versus vector quantities?

Since scalar quantities only provide numerical data, they are also known as one-dimensional quantities. In comparison, vector quantities are considered multidimensional quantities.\nVector quantities are mostly used in scientific and mathematical applications where direction is important information, whereas scalar quantities are used on a day-to-day basis. Combining and comparing vector quantities are also more complex than with scalar quantities, because direction is treated as another measurement in addition to the magnitude. In writing equations, a vector quantity's direction is writt..

Which of Newton's laws of motion deals with objects in motion staying in a straight-line motion unless acted upon by an unbalanced force?

Some examples of external forces include gravity, air resistance and radiation. Any physical force, however small or large, perturbs the uniform motion of an object. Considering that the universe is filled with forces, the notion of a state of uniform motion is more of an ideal, because every object and every particle is being acted on by any number of forces from one moment to the next.

What is a DC shunt motor?

Also known as a constant speed or constant flux motor, a characteristic of a shunt motor is its ability to maintain a constant speed under different loads without the use of a speed regulating control device. The motor regulates its own speed by taking advantage of its internal resistance. Its turning armature creates an electromagnetic field which is the source of the resistance. By applying a load to the motor, the armature slows and the resistance is reduced, giving it more strength. The balance of load to resistance allows the motor to maintain a constant speed. To change the speed of the ..

What are the intermolecular forces of ethanol?

The first force, London dispersion, is also the weakest. In London dispersion, the intermolecular attraction occurs between every molecule. This is caused by the exchange of electrons between each molecule when they are polarized temporarily. This temporary polarization occurs when the electron density is higher on one side of the molecule than the other.\nDipole-dipole attraction occurs because ethanol is a polar molecule with both one positively charged and one negatively charged end. Because the positive and negative charges are attracted to each other, the opposite poles of each molecule f..

What do the pulmonary arteries carry blood to?

Typically arteries carry oxygen-rich blood to the various organs, and veins return the de-oxygenated blood back to the heart. In the case of the pulmonary arteries, however, they transport de-oxygenated blood to the lungs to pick up oxygen. The pulmonary veins bring the oxygenated blood back to the heart where it is then directed out to the rest of the body.

What state has the largest number of volcanoes?

The U.S. Geological Survey has classified 18 volcanoes in the country to be extremely-high-threat volcanoes, five of which are found in Alaska. These include Akutan Volcano, Augustine Volcano, Makushin Volcano, Redoubt Volcano and Spurr Volcano. Most of Alaska's volcanoes are situated along the Aleutian Arc, which extends for 1,550 miles. Experts believe that eruptions originating from the Cook Inlet volcanoes, comprised of Augustine, Redoubt, Spurr and Iliamna, may result to severe damages and heavy casualties, as these volcanoes are closest to Anchorage, the state's most populous c..

How is ozone formed?

Ozone is formed naturally in Earth's upper atmosphere. When the oxygen gas (O2) in the atmosphere is exposed to ultraviolet light, the chemical bond between the two oxygen atoms is broken. The extra oxygen atom bonds with an existing O2 molecule in the atmosphere, forming ozone (O3).\nOzone is also formed from car exhaust, which contains nitric oxide (2NO), an unstable nitrogen and oxygen molecule. Nitrogen molecules naturally break apart when exposed to sunlight, which means that when the nitric oxide is released into the atmosphere it breaks down and releases a free oxygen atom, which b..

Who purchases recycled materials from recycling centers?

Most states have recycling programs that collect plastic, glass and paper from the homes of their residents. These materials are taken to recycling centers and then sold to manufacturers.One common item that is reused is paper. Paper mills by newspaper in bulk and then process it into new paper. The newspaper is taken to a facility and stripped of its ink, turned into pulp, screened to take out imperfections, mixed with new pulp made from wood and then pressed into new reams of paper.
