X kilograms of ice
SH means specific heat or heat capacity
HF means heat of fusion
Heat into ice
= X(20)SHice + X(HFice) + X(40)SHwater
=
Heat out of water
= 0.250(SHwater)(75-40)
An insulated beaker with negligible mass contains
0.250 kg of water at a temperatur 75.0°C.e of How many kilograms
of ice at a temperature of -20.0°C must be dropped into the water
to make the final temperature of the system 40.0°C?
