Answer:

Answer:
A restoration
Explanation:
the action of returning something to a former owner, place, or condition.
By use of combined gas law
P2= T2P1V1/V2
v1=5L
P1=540 torr
T1=25+273=298k
V2=15 L
T2=32+273=305 k
P2 is therefore=( 305k x 540 torr x5 L) /( 15L x 298)= 184.23 torr
Potential energy (Pe) = m*g*h
m = 4 kg
g = 10 m/s²
h = 3 m
And now:
Pe = 4*10*3
Pe = 120 Joules ou J
