Explain how the earth recycles and reuses it's own crust (Make it a paragraph)
Answer:
The interaction between the tectonic and the hydrologic systems causes constant recycling of the materials of the Earth's crust. Rocks are heated, metamorphosed, melted, weathered, sediment is transported, deposited and lithified, then it may be metamorphosed again in yet another cycle.
Explanation:
how is energy transfered from one piece of metal to another
Answer:
The positive and negative electrons attract leaving a shock and heat travels faster through metal than any other material such as plastic, wood, etc.
Explanation:
Answer:
The electrons in a piece of metal can leave their atoms and move about in the metal as free electrons. ... The hotter the metal, the more kinetic energy these vibrations have. This kinetic energy is transferred from hot parts of the metal to cooler parts by the free electrons.
Explanation:
why does condensation not occur on the outside of a warm glass of water?
Answer:
its called vapor. It can hold so much than colder eater based on the weather. For example if its cold it can heat up faster but if its hot it will maybe stay the same
A gas has a pressure
of 0.12 atm at 21.0°C.
What is the pressure at
standard temperature?
Answer:
0.12 it is 32.1 *C
Explanation:
at the standard temp
The pressure of the gas at 21°C is 1 atm. Then the pressure at the standard temperature i.e., at 25°C or 298 K is 0.14 atm.
According Gay- Lussacs law, the pressure of the gas is directly proportional to the temperature of the gas at constant volume.
hence, P1/T1 = P2/T2.
given,
P1 = 0.12 atm
T1= 21 °C
T2 = 25°C
then,
P2 = P1 T2/T1
= (0.12 atm ×21 °C)25 °C
= 0.14 atm
The pressure will increase from 0.12 atm to 0.14 atm when the temperature reaches its standard point.

Complex animals use their circulatory systems to provide their cells with water and
food. Plants do not have circulatory systems. What have they developed instead to
move nutrients and water?
Answer:
It is Xylem!
Explanation:
I just now took the test in Eduphoria. Just trust me, and you will get this right. I promise!
It is through circulatory system through which tissues get required oxygen, nutrients and also helps to remove waste products. The plants move water and nutrients through Xylem.
What is Xylem?The vascular tissue which carries water and minerals from the soil to the leaves and stems is defined as the xylem. It is composed of some specialized cells called tracheary components which carry water.
There are two types of xylem, they are primary xylem and secondary xylem. The primary xylem is developed during the primary growth of the plant whereas the secondary xylem is formed during the secondary growth of the plant.
The most important function of xylem is to transport water and minerals from the roots of the plant to other parts of the plant. This transportation occurs by passive transport which does not require any external energy.
The materials which flow through the xylem cell is called the xylem sap.
Thus xylem helps plants to move nutrients and water.

A photon has an energy of 4.0 x 10-19 Joules. What is the frequency of the radiation?
In the electromagnetic spectrum, the energy and frequency of radiation is given as, E=hυ where frequency is 0.603 ×10¹⁵ hertz.
What is electromagnetic spectrum?The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.The relation is given as,E=hυ where on substitution υ =E/h=4×10[tex]^-19[/tex]/6.626×10[tex]^-34[/tex]=0.603×10¹⁵ hertz
Thus, frequency of radiation is 0.603 ×10¹⁵ hertz.

Nistu is cooking rice in a pot. When she leaves the pot on the stove for a while, the temperature of the rice increases. What happens to the molecules of the rice when the temperature of the rice increases?
Answer:
Their average kinetic energy increases
Explanation:
The average kinetic energy of the rice molecules increases as the pot is left on the cooking stove.
Heat is transferred to the pot by conduction from the heat source. The heat is then transferred to the rice in the cooking pot by convection.
As the water in the pot heats up. The rice gains thermal energy. This causes the molecules of the rice particles to start vibrating. As the molecules vibrate about their fixed position, their thermal energy continues to increase.Therefore, the amount of heat absorbed by the rice increases with time and this actually cooks the food.Answer:
The energy of the molecules in the rice increases.

How many atoms are in 200.0 grams of Sulfur (S)?
Answer:
37.64 × 10²³ atoms
Explanation:
Given data:
Number of atoms = ?
Mass of sulfur = 200.0 g
Solution:
First of all we will calculate the number of moles of sulfur.
Number of moles = mass/molar mass
Number of moles = 200.0 g/ 32 g/mol
Number of moles = 6.25 mol
Number of atoms:
Avogadro number:
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
6.25 mol × 6.022 × 10²³ atoms / 1mol
37.64 × 10²³ atoms

I took the test it’s PROTONS
Answer:
Protons
Explanation:
Typically protons cannot be removed from the atom. Removing protons from an atom will completely change the atom as it will become another element entirely.
In an atom, protons are held by strong nuclear forces.
Within an atom, protons are the positively charged particles. Together with the neutrons, they are found in the nucleus of an atom. The number of protons within an atom is the atomic number of the atoms and it determines the nature and type of atom it is. Protons cannot be removed from an atom due to the strong binding force holding them together in place.Answer:

7. When substances are combined to form a mixture, they
A. keep their original properties
B. form new chemical bonds
C. form a new compound
D. cannot be separated physically
Answer: keep their original properties
Explanation: a mixture is, by definition, a combination of substances that do not interact, so they do not form new bonds/new compounds. They can usually be separated physically.
Mixtures are combinations of two or more individual components. However they can be separated physically based on their properties. They can form new bonds and compounds. Hence, options B and C are correct.
What are mixtures?Mixtures are formed by the combination of two or more substances by physical adherence or chemical bonds. They can be of homogeneous or heterogeneous.
Homogeneous mixtures appears as a single compound such as salt or sugar water they can form in one phase. Whereas, heterogeneous mixtures form two phases and appears to be separate.
There are many analytical tools to separate the components of mixtures such as chromatography, distillation, evaporation etc. The properties of mixtures will be different from that of the individual components. Hence, options B and C are correct.
