Is this right chemistry question


is this right?

The Heat Capacity (C) of Mercury is 0.140 J/g C


The change in temperature is calculated to be ΔT= 356.73 - (-38.83) = 395.65 °C




Using the formula E= (0.140 J/gC)(53.5 g)(395.65 °C)= 2941.58 J

There are actually TWO phase changes. It goes from a solid to a liquid and then from a liquid to a solid, unless you assume it simply sublimed, in which case you’d need delta H sublimation
