Answer:
Gravitational force is also decreases.
Explanation:
Gravitational force is directly proportional to the mass of an object and inversely properly to the distance between their centres. Directly means if one increases the other automatically increases or if one decreases, the other also decreases. There is a direct relationship between mass and gravitational force so if mass of the bodies decrease, the gravitational force is also decreases.
We use the formula:
ΔP = (ΔH / ΔV) ln(T2 / T1)
where,
ΔH = change in enthalpy from solid to liquid = 4810 J/mol
ΔV = change in volume from solid to liquid = 0.55 cm^3/mol
T2 = 620 K, T1 = 600 K
So,
ΔP = (4810 / 0.55) ln(620 / 600)
ΔP = 286.76 J/cm^3
or converting to atm:
