Explanation:
1.
We have the expression for the root mean square velocity of the molecules of gases as:
[tex]v_{rms}=\sqrt{\frac{3.k_b.T}{M} }[/tex]
where:
[tex]k_b=[/tex] Boltzmann constant
[tex]T=[/tex] temperature of the gas
[tex]M=[/tex] molecular mass of the gas
2.
In a coal-fired powered the types of energy form start to finish can be given as;
3.
In a coal fired power plant the approximate percentage of original energy in the coal lost to heat is approximately 60%.
