Question

q6.6 approximately how many tons of lignite would be required to produce the amount of heat generated by one ton of anthracite coal?

Explanation:

Step1: Identify heat - energy values

We need to know the heat - energy content per ton of lignite and anthracite coal. Let's assume the heat content of anthracite coal is \(x\) BTUs per ton and the heat content of lignite is \(y\) BTUs per ton (\(x>y\)).

Step2: Calculate the amount of lignite

The amount of lignite \(A\) required to produce the same heat as one ton of anthracite is given by the ratio of the heat content of anthracite to the heat content of lignite. So \(A=\frac{x}{y}\) tons.

However, without specific heat - energy values for lignite and anthracite (for example, anthracite typically has a heat content of around 25 million BTUs per ton and lignite around 8 million BTUs per ton), we can't give a numerical answer. If we assume these values, then \(A = \frac{25000000}{8000000}\approx3.125\) tons.

Answer:

Without specific heat - energy values, we can't give a definite answer. If we assume anthracite has 25 million BTUs per ton and lignite has 8 million BTUs per ton, approximately 3.125 tons of lignite would be required.
