thermal conduction and convection processes we explain the temperature profile: warmer at the bottom and colder at the top

Temperature is a measure of the internal energy of molecules.

When the pot is on the burner, the lower part of the pot acquires energy from the flame, this energy increases the temperature of the metal that is in contact with the liquid from the bottom, by a process of thermal conduction, while the liquid in the top is kept at the same temperature.

As time progresses, the hotter lower liquid, for which it has a lower with the metal bottom heats up by conduction. density, conscientiously rise and a transfer of heat is created by convection, which raises the temperature of the hot liquid and makes the liquid fall that is colder from the upper part than at the coming into contact

This cycle is repeated heating all the liquid. But the liquid with the liquid in the lower part always at a higher temperature than the liquid in the upper part, the process stops when the liquid in the lower part reaches the boiling point, than the passage from liquid to gas, during which the temperature remains constant.

With the thermal conduction and convection processes we explain the temperature profile: warmer at the bottom and colder at the top.

If the p-side has a higher doping concentration, explain how to keep tuning to the same radio channel?
zzz [600]

Answer:

increase in temperature of the intrinsic semiconductor

Explanation:

  • If the p-side has a higher doping concentration, it implies that number of holes (positive ion) increased which is greater than number of electron (negative ion) in the n-side
  • in order to balance the intrinsic concentration, that is to balance the number of holes and electrons which depends on temperature.
  • an increase in the temperature of the intrinsic semiconductor (p-side), increases the number of electron but number of holes remains constant.

A balance in the intrinsic concentration helps in tuning to the same radio channel.

Both protons and neutrons (and their anti-particles) froze out:
VladimirAG [237]
I think Both protons and neutrons (and their anti-particles) froze out at 1013 K, about 0.0001 seconds after the Big Bang. Protons and neutrons are sub atomic particles of an atom that are found in the nucleus of an atom. Proton is the positively charge particle while the neutron has no charge. The proton positive charge accounts for the positive nuclear charge.

How many total electrons can be contained in the 4d sublevel? <br> 2<br> 6<br> 10<br> 14
qaws [65]
<span>The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max. And the 4 sublevel has 7 orbitals, so can contain 14 electrons max.
So, having this in mind, 10 electrons in total can be contained in the 4d sublevel.

Your apple juice has a molarity of 3.4 M and a volume of 0.895 litres. What does a student have to do to decrease the molarity t
Jlenok [28]

Answer:

4.285 L of water must be added.

Explanation:

Hello there!

In this case, for this dilution-like problems, we need to figure out the final volume of the resulting solution so that we would be able to obtain the correct volume of diluent (water) to be added. In such a way, we can obtain the final volume, V2, as shown below:

M_1V_1=M_2V_2\\\\V_2=\frac{M_1V_1}{M_2}

Thus, by plugging in the initial molarity, initial volume and final molarity (0.587 M) we obtain:

V_2=\frac{3.4M*0.895 L}{0.587M}\\\\V_2=5.18L

It means we need to add:

V_{H_2O} ^{added}=5.18L-0.895L=4.285L

Of diluent water.

Regards!
