how much energy would it take to heat a section of the copper tubing that weighs about 720.0g from 15.29 degrees to 27.71 degrees

Heat can be calculated using the following formula:

q=mcΔT

m=mass of the substance

c=specific heat

ΔT=temperature difference

= (0.3850 (J/g) ⋅∘C) x (720.0 g) x (27.71 - 15.29) ∘C

= (0.3850 x 720 x 12.42) J

=3442.8 J

So, 3442.8 J of energy required to heat a section of the copper tubing that weighs about 720.0g from 15.29 degrees to 27.71 degrees.
