If you mix 10.5 gm of steam at 100 C with 1,010.0 gm of ice at 0
C what is the change in entropy? Heat of fusion = 79 cal/gm, Heat
of vaporization = 540 cal/gm
Steam at 100°C is added to ice at 0°C.
(a) Find the amount of ice melted and the final
temperature when the mass of steam is 13.0 g and the mass
of ice is 45.0 g.
g
°C
(b) Repeat this calculation, when the mass of steam
as 1.30 g and the mass of ice is 45.0 g.

Steam at 100°C is added to ice at 0°C.
(a) Find the amount of ice melted and the final temperature when
the mass of steam is 11 g and the mass of ice is 49 g.
(b) Repeat with steam of mass 2.0 g and ice of mass 49 g.
2. You mix 50 grams of ice at 0.0 degrees C and 50 grams of
steam at 100 degrees celsius. What is the equilibrium temperature?
The earth receives on average 240 W of power per square meter.
Using the Stefan-Boltzmann law, calculate the predicted average
Earth’s temperature (assume e=1). From a web-search find the
average Earth temperature and the primary reason the value you
calculated is too low?
Steam at 100°C is added to ice at 0°C. Find the temperature when
the mass of steam is 10 g and the mass of ice is 50 g. The specific
heat of water is 4186 J/kg°C, its latent heat of fusion is 3.33x105
J/kg and its heat of vaporization is 2.26x106 J/kg.
What mass of steam at 100∘C must be added to 1.80 kg of ice at
0∘C to yield liquid water at 20 ∘C? The heat of fusion for water is
333 kJ/kg , the specific heat is 4186 J/kg⋅C∘ , the heat of
vaporization is 2260 kJ/kg .
If 200 g of ice at 0°C and 50 g of steam at 100°C interact
thermally in a well-insulated container. The final state of the
system will be;
( is loved it and got Tf= 64C ) ( so please choose an answer
from the following multiple choices )
(a) A water steam mixture at 100°C
(b) Water at a temperature between 0°C and 50°C (c) 0.089 kg
(d) 0.12 kg
(e) A ice-water mixture at 0°C
What mass of steam at 100∘C must be added to 1.90 kg of ice at
0∘C to yield liquid water at 15 ∘C? The heat of fusion for water is
333 kJ/kg , the specific heat is 4186 J/kg⋅C∘ , the heat of
vaporization is 2260 kJ/kg .
Saturated steam at 100 C is heated to 400 C. Use the steam table
to determine the required heat input if continuous stream flowing
at 150 kg/min undergoes this process at constant pressure.
Ice of mass 45.5 g at -10.5° C is added to 208 g of water at
15.8° C in a 101 g glass container of specific heat 0.200 cal/g-°C
at an initial temperature of 27.5° C. Find the final temperature of
the system.
