Part A D How much heat in kilojoules is evolved in converting 2.00 mol of steam at 150 °C to ice at -50.0 °C? The heat capacity of steam is 1.84 J/g°C and that of ice is 2.09 J/gºC. Remember that if heat is leaving the system, then q is a negative number and if heat is entering the system, then q is a positive number. q= ΜΕ ΑΣΦ ? kJ
