Answer 8

hello

Answer 9

@iambatman calculate the amount of energy in joules required to change 10 grams of solid mercury at its melting point to mercury vapor at the boiling pt. the melting point, boiling point and specific heat capacity are -39C 375C and 0.140 J/gC, respectively. heat of fusion= 11.4 J/g heat of vaporization; 295 J/g. Compare with amount of heat needed to change 10 grams of ice at 0C to steam @100C I WILL GIVE GOLD MEDAL AND SUBWAY FOR ANSWER!!!!!!!!!!!!
