in an experiment, 15.0 g of ice at -30 celsius is
converted into steam with a temperature of 115 celsius. How much
energy is required for this process? DHvap= 2260 J/g; DHfus= 334
J/g; cs(ice)= 2.06 J/(g celsius; cs(water)= 4.18 J/(g celsius;
cs(steam)= 1.99 J/(g celsius))
190 g of ice at 0 ºC is mixed with 49 g of steam at 100 ºC to
make water. The latent heat of fusion of water is 33.5 × 104 J/kg,
and the specific heat of water is 4186 J/kg∙K, the latent heat of
vaporization of water is 22.6 × 105 J/kg.
A) Determine the amount of heat released by steam at 100*C to
make water at 100*C.
B) Determine the amount of heat absorbed by ice at 0*C...
How much heat is needed to convert 80 g of ice initially at
-10⁰C into 60g of water and 20 g of steam at 100⁰C.
Data:
- Specific latent heat of melting ice and that of water
vaporization: Lf = 334 kJ / kg and Lv = 2260 kJ / kg
- Thermal mass capacity of water, ice and that of water vapor:
cwater = 4.2 kJ / kg.K; cice = 2.1 kJ / kg.K
and cvapor = 2.0 kJ...
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.

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.
After eating cookie dough ice cream and mixed berry ice cream
for a month,
Cookie Monster has decided that he wants just one ice cream that he
can
get that has both cookie dough and mixed berries. Linda and Tony
have
decided that they can combine the two ice creams together for their
best cus-
tomer. However, they want to make as much money as possible for
blending
these two together. They want to charge customers in proportion to
how...
20 kg of steam at 1000C is passed into a
mixture of 30 kg of ice and 100 kg of
water at 00C . Find the resulting temperature if the
water equivalent of the
vessel is 10 kg.
