What would happen if you put bubble wrap around an experiment of heat energy

The air pressure would build up resulting in a high air density.

Explanation: Heat energy builds up air pressure. And if you surround it with bubble wrap, that air pressure will have nowhere to release to. And so because of that, high air density occurs.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
