What is responsible for the high electrical conductivity of a metal

Answers

Answer 1

Answer:

Electrical conductivity in metals is a result of the movement of electrically charged particles. Because valence electrons are free to move, they can travel through the lattice that forms the physical structure of a metal.

How does energy change form when friction causes the temperature of an object to increase?

Answers

I believe the answer would be through the movement of the molecules, the higher the temperature the more the molecules move around and vibrate.

Friction causes the molecules on rubbing surfaces to move faster, therefore they have more energy. This gives them a greater temperature, and they feel warmer.

What is friction ?

The term friction is defined as the resistive force that occurs when two bodies in contact move relative to one another.

Adhesion between body surfaces, and the adhesion is the molecular force that occurs when two materials come into contact with each other are the causes of friction.

Friction is an everyday force that is generated by two surfaces when they are interacting. When these surfaces slide against each other, this interaction increases the thermal energy of the two surfaces.

Thus, Friction causes the molecules on rubbing surfaces to move faster, therefore they have more energy.

A scientist observes hot water erupting from a vent in the Earth.What most likely caused the water to rise and erupt from the vent? someone pls answer i if u answer u get 57 points

Answers

Answer/Explanation:

A geyser is hot water erupting from a vent in the earth. Geysers are somewhat rare and occur in certain parts of the earth. Underneath, there are hidden chambers that provide constant flows of water. Sometimes when the tectonic plate of the earth move, it leaves gaps in between the hot earth's inner core and the ground. The magma inside is able to heat up the water from the earth. Since hot particle tend to rise, the water explodes out of the vent with such power from the heat.

why is density a property of substances

Answers


Density is a physical property of matter that expresses a relationship of mass to volume. The more mass an object contains in a given space, the more dense it is.

Since different substances have different densities, density measurements are a useful means for identifying substances.

Answers

Answer:

33300J

Explanation:

Given parameters:

Mass of ice  = 100g

Unknown:

Amount of energy = ?

Solution:

This is a phase change process from solid to liquid. In this case, the latent heat of melting of ice is 3.33 x 10⁵ J/kg.

 So;

            H  = mL

m is the mass

L is the latent heat of melting ice

  Now, insert the parameters and solve;

            H = mL

 mass from gram to kilogram;

            100g gives 0.1kg

  H = 0.1 x 3.33 x 10⁵ = 33300J

As the elements in Period 2 are considered in order from lithium to fluorine, there is an increase in the effective nuclear charge and increase in the ionization enthalpy.

What is effective nuclear charge?

Effective nuclear charge of an atom is the attraction force of positive charge of  protons present inside the nucleus acts as an  valence electrons.

The effective nuclear charge is alway slower  than the total number of protons of the nucleus because of  shielding effect. Where Z is the atomic number and S is the number of shielding electrons.

Therefore, the elements in Period 2 are considered in order from lithium to fluorine, there is an increase in the effective nuclear charge and increase in the ionization enthalpy.

PLZ HELP IRS DUE TODAY

Answers

Answer:

the light comes from the sun

Explanation:

the light from the sun reflects on the moon and the moon gets its light.

The moon is always half-lit by the light that comes from the sun except during the lunar eclipse. The light source for the moon is the sun.

What are the phases of the moon?

The lunar phase or Moon phase can be described as the shape of the Moon's directly sunlit portion, which can be demonstrated quantitatively using areas or angles, or qualitatively utilizing the terminology of the four major phases: new moon, first quarter, full moon, last quarter.

The lunar phases gradually change over a month as the Moon's orbital positions around Earth and the position of the Earth around the Sun shift. The visible side of the Moon is sunlit, according to the position of the Moon in its orbit.

Thus, this face's sunlit part of the moon can vary from 0% to 100%. Each of the 4 major lunar phases is approximately 7.4 days, with +/− 19 hours in variation due to the elliptical shape of the orbit of the Moon.

He loved maps, as I have told you before; and he also liked runes and letters and cunning handwriting, though when he wrote himself it was a bit thin and spidery..'Moon-letters are rune-letters, but you cannot see them,' said Elrond, 'not when you look straight at them. They can only be seen when the moon shines behind them, and what is more, with the more cunning sort it must be a moon of the same shape and season as the day when they were written.'"2."Bilbo never forgot the way they slithered and slipped in the dusk down the steep zig-zag path into the secret valley of Rivendell. The air grew warmer as they got lower, and the smell of the pine-trees made him drowsy, so that every now and again he nodded and nearly fell off, or bumped his nose on the ponys neck. Their spirits rose as they went down and down."3.'Dont dip your beard in the foam, father!' they cried to Thorin, who was bent almost on to his hands and knees. 'Its long enough without watering it.' 'Mind Bilbo doesnt eat all the cakes,' they called. 'He is too fat to get through key-holes yet.' 'Hush, hush. Good People! and goodnight!' said Gandolf, who came last. 'Valleys have ears, and some elves have over merry tongues. Good night!' And so at last they all came to the Last Homely House, and found its doors flung wide.""'Is that The Mountain?' asked Bilbo in a solemn voice, looking at it with round eyes. He had never seen a thing that looked so big before.4.'Of course not!' said Belin. 'That is only the beginning of the Misty Mountains, and we have got to get through, or over, or under those somehow, before we can come into Wilder land beyond. And it is a deal of a way even from the other side of them to the Lonely Mountain in the East where Smaug lies on our treasure.'"
