How much heat is required to raise the temperature of 20.9 g20.9 g of water from −25 °C−25 °C to 155 °C? the answer are not 1.45 *10^5 and 10.956778 ! you have to calculate be broken 1.down into five step! heart the ice from -25 c to 0 c

2.melting the ice

3.heating the liquid water from 0c to 100 c

4.100 c to 155 c

0.497 cal/ g c to do this calculate

All this answer 12298.782 and 10.956778 are wrong ,please make sure you understand the question before answering it.Thanks
