Acan as soft drink at room temperature is put into refrigerator so that it will cool. would you model the can of soft drink a closed system or an open system .explain

b.

hope this : )

i will answer your question if you answer mine

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

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
