(b) How much ice remains when the system reaches equilibrium?
A window of a car is found to be covered with 0.9 cm of ice. If the area of the window is 1 m2, and the ice is at -12 degrees Celsius, what is the minimum heat required to melt all the ice? Take the density of ice to be 900 kg/m3, the specific heat capacity of ice to be 0.5 cal/gK and the latent heat of fusion to be 80 cal/g.
You have 54 g of steam at 100°C.
How much heat must be removed to change
it to 54 g of water at 20°C? The specific heat
of water is 4180 J/kg -° C and its latent heat
of vaporization is 2.26 x 106 J/kg.
Answer in units of J.
