CO2 (s) and CO2 (g)
The answer is rusting of metal such as iron. Iron is the most common metal in the world and has been mined and used in numerous construction of economic importance such as buildings , boats, water pipes, and etcetera. However, the redox reaction between iron and oxygen weakens the metal through rusting (which makes the metal brittle).
4 Fe2+ + O2 → 4 Fe3+ + 2 O2−
One way to lessen the effects of rusting is through galvanization (which is the application of a thin protective layer of metal such as zinc on the iron) or by painting the iron metal.

Answer:
5150 kPa
Explanation:
Given that,
Initial volume, V₁ = 100 mL
Initial pressure, P₁ = 103 kPa
Final volume, V₂ = 2 mL
We need to find the new pressure of the gas. The relation between the pressure and the volume of gas is given by :
So, the new pressure is 5150 kPa.
MICROWAVEOVENS
In a microwave oven, microwaves emitted by a small antenna are directed into the cooking compartment, and as they enter, they pass a set of turning metal fan blades.
