The total change in internal energy would simply be
calculated using the formula:
ΔU = -P (V2 – V1) + ΔH
where ΔU is the change in internal energy; P is constant
pressure = 30 atm = 3,039,750 Pa; V2 is final volume = 2 L = 0.002 m^3; V1 is
initial volume = 7.20 L = 0.0072 m^3; while ΔH is the heat = -74,400 J (heat
released so negative)
Therefore:
ΔU =-3,039,750 Pa * (0.002 m^3 - 0.0072 m^3) + (- 74,400
J)
<span>ΔU = - 58,593.3 J = - 58.6 kJ</span>
Hey there, The answer is A. Free electrons.

Explanation: No speak Spanish
Answer:
It's explained by nebular theory, which describes the forces and processes at play as a nebula spins and accretes into a star and its planets orbiting it. A key piece of information to always keep in mind is that the force of gravity is responsible for accretion and all the objects it forms.
