How much total heat is required to heat 3316 g of ice at -16.12 oC to all steam at a temperature of 128.08 oC?


how do you carry out the five step process?

1 answer

Heat needed to raise the temperature of ice from -16.12c to 0c=mcT
=3.316*2100*16.12
=112253.23 joules

Heat to melt the ice=mL
=3.316*336000
=1114176 joules

Heat needed to raise the temperature of the water from 0c to 100c=mcT
=3.316*4200*100
=1392720 joules

Heat needed to vaporise 3.316kg of water=mL
=3.316*2260000
=7494160 joules

Heat needed to raise the temperature of steam from 100c to 128.8c=mcT
=3.316*2100*28.8
=200551.68 joules

Total heat required= 112253.23+1114176+1392720+7494160+200551.68
=10313860 joules
