An example is when on a seesaw if a kid is on one side and an adult is on the other then it is unbalanced because the adult weighs more
Answer:

Explanation:
Given that;
The energy gap between the valence band and the conduction band in the widely-used semiconductor gallium arsenide (GaAs) is Δ = 1.424 eV.
So; that implies that:

Suppose that we consider a small piece of GaAs with 1020 available electrons, -- This is taking about the numbers of electrons used which is :

Temperature is given as:

Number of electrons can be calculated by using the formula;

Answer:
The oxygen and water in air react with the metal to form the hydrated oxide. The familiar red form of rust is (Fe2O3), but iron has other oxidation states, so it can form other colors of rust
