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...
