Answer:
941.4 kPa
Explanation:
To solve this problem, we can use Boyle's Law, which states that:
"For a fixed mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"
Mathematically:
where
p is the pressure of the gas
V is its volume
For a gas transformation, the equation can be rewritten as
where in this problem:
is the initial pressure
is the initial volume
is the final volume
Solving for p2, we find the final pressure:

<h2>Enthalpy Difference</h2>
Explanation:
- The 2nd Law of Thermodynamics states that when energy is converted from one form to another, some is always lost due to difference in the enthalpy of the system, which always increases.
- Enthalpy may be defined as the amount of energy that is stored.
- During a chemical reaction, the system will absorb or gives out energy in the form of heat and light.
- The change in energy during a chemical reaction is due to the difference in the energy amount of reacting species and species that are formed.
Metal that won't be oxidized:
Metal that will not be able to oxidize by any of the other metals is gold.
What causes oxidation to happen?
This chemical reaction might take place in the air or after the metal has been in contact with acids or water. The most prevalent example is corrosion of steel, which occurs when the iron molecules on the surface of steel change into iron oxides, most frequently Fe2O3 and Fe3O4.
If you've ever seen a rusted-out vehicle or corroded metal bits, you've witnessed oxidation in action.
Metals that don't oxidize:
In their native condition, noble metals like platinum or gold resist oxidation. Ruthenium, rhodium, palladium, silver, osmium, and iridium are more examples of these metals. Humans have developed a wide variety of corrosion-resistant alloys, including brass and stainless steel.
