C) a standard cubic foot of natural gas carries with it about 1.1 x 106 j of energy. natural gas currently costs about $16.25 per thousand cubic feet. how many joules of energy in the form of natural gas can you get for a dollar?

d) a short ton of coal holds about 2.24 x 107 j of energy and costs about $56.45 per short ton. how many joules of energy in the form of coal can you get for a dollar?

67692.31 J

396811.337 J

Explanation:

(a) The cost of standard cubic foot of natural gas = $16.25

The energy related to standard cubic foot of natural gas =

Thus, As according to the question,

$16.25 of natural gas have of energy.

$1 of natural gas have of energy.

The amount of energy = 67692.31 J

(b) The cost of one short ton of coal = $56.45

The energy related to the short ton of coal =

Thus, As according to the question,

$56.45 of coal have of energy.

$1 of coal have of energy.

The amount of energy = 396811.337 J
