from an external source of power
Explanation:
The energy needed for nuclear fusion comes from an external source of power.
Nuclear fusion is the combination of small sized atomic nuclei to form larger ones.
The reaction releases a huge amount of energy but also requires a large activation energy to start up.
- The energy input require to drive two nuclei into fusion comes from an external source.
- Nuclear fusion has a high activation energy which serves as the energy barrier for this reaction to take place.
- The energy comes from the surrounding and once initiated, spontaneous chain reactions are set up.

Initial Conditions:
Volume= v1= 417 cm³
Temperature= T1 = 278 K
Final Conditions:
Temperature= T2 = 231K
Volume = v2 =?
Use the general gas equation;
P1*v1/T1 = P2*v2/T2
As, the temperature is constant;
So,
v1/T1 = v2/T2
417/278 = v2/231
v2= 346.5 cm³
