Calculate the amount of energy in joules required to change 10 g of solid mercury at its melting point to mercury vapor at the boiling point. the m_p, b_p, and specific heat of mercury are -39^degree c, - 375^degree c, and 0.140 j/g^degree c, respectively. compare with the amount of heat needed to change 10 g of ice at 0^degree c to steam at 100^degree c.
