We can use the formula: q = m*c*ΔT
where q is the amount of heat, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature.
Substituting the given values, we get:
q = (7.25 g) * (2.20 J/g-K) * (57.0 °C - 22.0 °C)
q = 558 J
Therefore, the answer is B) 558 J.

The Specific Heat Capacity of Methane Gas Is 2
