anonymous · Answer

use heat lost by water = mass of ice * Latent heat of ice

anonymous · Answer

in CGS 
240 * 1*(50-0)  = m* 80

m =150g

anonymous · Answer

Q =m cp delta T
this formula ya used for second one ???

anonymous · Answer

H = mass * specific Latent heat
H= M*L  (symbols have standard meaning )
