Explanation:
Answer: As an object is heated up, its atoms and molecules move and collide faster.
Explanation: Geothermal energy is the thermal energy in the earth. Wind. The total kinetic energy of the particles that make up a substance. Thus when the heat is added to the system, the temperature gets increases which in turn will increase the velocity of the molecule and these molecules will collide even faster .

9) What is the final pressure in the container shown below after the valve is opened and the gases are allowed
to flow? (The gases do not act)
0
4.00 am
3.00
NE
2.00 am
2.00 L
A 3.00-L container with O₂ at 4.00 atm is connected to a 2.00-L container with Ne at 2.00 atm, resulting in a final pressure of 3.20 atm in the container.
We have 2 containers connected by a valve.
One container has a volume of 3.00 L and contains O₂ at 4.00 atm. The other container has a volume of 2.00 L and contains Ne at 2.00 atm.
When the valve is opened, the total volume is the sum of the 2 containers.
[tex]V_2 = 3.00 L + 2.00 L = 5.00 L[/tex]
Assuming constant temperature and ideal behavior, we can calculate the final pressure of each gas using Boyle's law.
O₂
[tex]P_1 \times V_1 = P_2 \times V_2\\\\P_2 = \frac{P_1 \times V_1}{V_2} = \frac{4.00atm \times 3.00L}{5.00L} = 2.40atm[/tex]
Ne
[tex]P_1 \times V_1 = P_2 \times V_2\\\\P_2 = \frac{P_1 \times V_1}{V_2} = \frac{2.00atm \times 2.00L}{5.00L} = 0.800atm[/tex]
The final pressure in the container will be the sum of the final pressures of the gases.
[tex]P = 2.40 atm + 0.800 atm = 3.20 atm[/tex]
A 3.00-L container with O₂ at 4.00 atm is connected to a 2.00-L container with Ne at 2.00 atm, resulting in a final pressure of 3.20 atm in the container.

why does magnesium in an aqueous solution of magnesium chloride conduct electricity but solid magnesium chloride does not?
Answer:
Delocalized electrons
Explanation:
Magnesium Chloride is an ionic compound, so its lattice structure prevents the flow of electrons. However, when you convert the ionic compound into an aqueous solution it allows movement of electrons/ions due to the breakdown of the molecular forces which make it conductible. In short, Ionic compounds as a solid are not conductible but they are in an aqueous form.
Describe the nucleus of the
atom.
Answer:
The nucleus of atom is composed of two subatomic particles that each have charges.
Protons, which are positively charged particles.Neutrons, which are neutrally charged particles.Both reside in the nucleus of an atom. The amount of protons and neutrons (Electrons can to) is what helps us identify each atom apart. Electrons are NOT in the nucleus of atom but orbit it in outer layers called orbitals.

Which are effects of long-term exposure to mustard gas? Select all that apply. One, some, or all responses may be correct.
The effects of long-term exposure to mustard gas causes mortality and chronic respiratory disease.
Exposure to mustard gas in the long term can result in mortality from influenza, pneumonia as well as chronic breathing disease. Exposure for long term leads to respiratory complications and septic shock. Extensive breathing in the environment of mustard gas can cause chronic respiratory disease, respiratory infections or death.
Extensive eye exposure to this gas can cause permanent blindness. Exposure to mustard gas may also increase the chances of lung and respiratory cancer so we can conclude that mustard gas is lethal and can cause a number of diseases in a person who is exposed to it.

Explanation:
Some copper is palced in a previouly weighted crucible and reweighed .
Mass of crucible + copper = 5.92g
Mass of crucible = 4.65g
Clculate the mass of copper used in the experiment
We can find the mass of copper by finding the difference between the mass of the crucible and the copper, and just the crucible. This is possible since the mass that is left would be attributed to just the copper.
Mass of copper = (Mass of crucible + copper) - Mass of crucible
= 5.92 g - 4.65 g
= 1.27 g

wht will react with acid to giv bluish green salt nd water ??
Explanation:
When dilute HCl is added to a small amount of copper oxide in a beaker, a greenish-yellow gas is released and a bluish-green solution is formed. Since the metal oxides such as a Copper oxide (CuO) are basic in nature, it reacts with acids such as HCl to form the corresponding salt and water.
