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 .
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 .
100 g of solid ice at 0°C is added to 500 g of liquid water at
90°C. What is the final temperature? What is initial water
temperature is required so that 10 g of ice remain once equilibrium
has been reached?
The heat of fusion of ice is 80 cal/g at 0 °C and 1 atm, and the
ratio of the specific volume of
water to that of ice is 1.000:1.091. The saturated vapor
pressure and the heat of vaporization of
water at 0 °C are 6.026 × 10-3 atm and 600 cal/g, respectively.
Estimate the triple point of water
using these data
How much heat energy is required to liquify a 4.40-g ice cube at
-6 °C? (heat of fusion of ice is 333 000 J/kg, specific heat of ice
is 2090 J/kg⋅°C
