Calculate the amount of heat (calories) required to make ice m(g) of T1 (¡ÆC) to T2 (¡ÆC) water.

¢º Heat required to make ice of T1¡É to ice of 0¡É

 Q1 = m*ic*¥ÄT = m*ic*(0-T1)
 ic : specific heat of ice (cal/g¡É)

¢º Heat required to make ice of 0¡É to water of 0¡É

 Q2 = m*lh
 lh : latent heat of ice (cal/g)

¢º Heat required to make water of 0¡É to water of T2¡É

 Q3 = m*wc*¥ÄT = m*wc*(T2-0)
 wc : specific heat of water (cal/g¡É)

¢º Total heat required

 Q = Q1+Q2+Q3 = m*(ic*(0-T1)+lh+wc*(T2-0))

*** Âü°í¹®Çå[References] ***

Q = m*(ic*(0-T1)+lh+wc*(T2-0))
