First, you have to understand what convection is.

Did you know that the hotter something, the more it expands? This happen because heat, at an atomic level, is nothing but vibration. If a liquid is hot, it means that there is more vibration between it's atoms. And, more vibration causes to have more space between the atoms, which causes the density to decrease.

So, when a liquid has it's top cold, and it's bottom hot, the top will be more attracted by the gravity than the bottom, because it's more dense. This will cause the top to want a lot to get down, and the bottom, because of the pressure of the top, will want to go up. This will cause a spiral movement; the bigger the difference, the faster and the more violent this spiral movement will be (and that's what causes hurricanes)

So, what this has to do with Earthquakes and stuff?

The Earth, when it was formed, was really, REALLY hot. It has being losing it's heat ever since, but, since there is not air in the space, it can only lose it's eat though radiation, which is very  slow. And also, the bigger something is, the slower it cools down, because there is more vibration, more movement, more energy to be lost. The earth was formed 4,5 BILLIONS of years ago. That's A LOT of time. But the lost of heat by radiation is so slow, and the earth has so much heat to be lost, that it still didn't cool down that much.

You can think of Earth like a hot potato that got out of the oven just a little ago; the outer part is already cold, but just take a bite, and you will see how HOT it's insides are. You can't take a bit out of earth, of course, but it's insides are a lot hotter that the outside, because it's the outside that loses eat. The insides have to wait for the outsides to cool down, and then lose eat to the outside.

So... we got a planet that's really hot in the inside, so hot that it's mantle is made out of liquid rocks!

So, now, it's the time to connect the dots: the upper part of the mantle loses heat faster than the inner one. This causes a spiral movement, and, since the tectonic plaques are floating in this liquid, they move as well!

When two plaques move one against each other, they crash against themselves, and this causes an earthquake. If they keep moving against each other, one will go down and the other will go up, forming a montain. If they move away, this creates an open space; and since the liquid of the mantle has, like, THE WHOLE CRUST OF THE PLANET CRUSHING IT, the mantle is craving to get out, so when there is an opening, it squirts out like crazy, creating an eruption. After a while, the magma solidifies, creating a volcano.

A beaker contains 0.125 L of a 3.00 M solution. If the volume goes up to 0.325 L, what is the new molarity?
igor_vitrenko [27]

Answer:

1.15 M

Explanation:

Step 1: Given data

  • Initial volume (V₁): 0.125 L
  • Initial concentration (C₁): 3.00 M
  • Final volume (V₂): 0.325 L
  • Final concentration (C₂): ?

Step 2: Calculate the final concentration of the solution

We want to prepare a dilute solution from a concentrated one by adding water. We can calculate the concentration of the dilute solution using the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁/V₂

C₂ = 3.00 M × 0.125 L/0.325 L = 1.15 M

2 moles of sodium chloride are dissolved in 8 liters of water. What is its molarity (M) ?
otez555 [7]

Answer:

0.25M

Explanation:

Since molarity is defined as the amount of substance in 1 liter of a solution, and amount in chemistry refers to the number of moles, molarity can be found using the equation below:

Molarity= number of moles ÷ volume in liters

Given: number of moles= 2

Volume= 8L

∴ Molarity of NaCl

= 2 ÷8

= 0.25M

Svet_ta [14]

Answer:

Now that you have the knowledge of the highest specific heat capacity and lowest porosity, which material would you choose to build Rover's new doghouse roof?

Oak has the highest heat capacity; therefore, oak can absorb a lot of heat without raising its temperature. This is good for very hot areas. Concrete has the lowest porosity so water will not leak through its pores and drip into the doghouse. This is good for rainy areas. However, clay is second on both lists and might be a good choice overall for hot and rainy weather conditions. Rover should be happy with this.

Answer: The last electron will be filled in first orbital of 3p sub-shell.

Explanation: Filling of electrons in orbitals is done by using Hund's Rule.

Hund's rule states that the electron will be singly occupied in the orbital of the sub-shell before any orbital is doubly occupied.

For filling up of the electrons in Sulfur atom having 16 electrons. First 10 electrons will completely fill according to Aufbau's Rule in 1s, 2s and 2p sub-shells and last 6 electrons are the valence electrons which will be filled in the order of 3s and then 3p.

3s sub-shell will be fully filled and the orbitals of 3p sub-shell will be first singly occupied and then pairing will take place. Hence, the last electron will be filled in the first orbital of 3p-sub-shell.
