Reference no: EM13383265

Calculate the amount of energy in kilojoules needed to change 243 g of water ice at -10 rm ^{circ}C to steam at 125 rm ^{circ}C. The following constants may be useful:

* Crm _m~(ice) = 36.57 ~J/(molcdot{}^{circ}C)
* Crm _m~(water) = 75.40 ~J/(molcdot{} ^{circ}C)
* Crm _m~(steam) = 36.04 ~J/(molcdot{} ^{circ}C)
* Delta H_{rm fus} = +6.01 ~{rm kJ/mol}
* Delta H_{rm vap} = +40.67 ~{rm kJ/mol}
