Find the amount of heat required to change 10g of ice at -5c to water at 20c.
m=10g
Specific heat of ice= 0.5
Latent heat of fusion from ice to water L= 80cal
Specific heat of water=1
Latent heat of vaporization L= 540cal
Total heat required Qtotal?=Q1?+Q2?+Q3?+Q4?
Qtotal?=25+800+1000+5400
Qtotal?=7225cal
