QUESTION 8 How does the internal energy of the ice and water mixture change if the temperature does not rise while the ice is melting? It decreases, because you need to use energy to make a freezer run, but ice melts spontaneously. No enough information to determine. It increases, because it takes more energy for water molecules to be disordered than to be ordered. It remains the same, because both are at the same temperature. QUESTION 9 Suppose you start...

Question 13 (1 point) How much heat (in MJ) does it take to completely convert 0.80 kg of ice initially at a temperature of -15°C to steam (water vapor) at a final temperature of 130°C? Specific heats (in J/kg.K): ice (2100), water (4190), steam (2000) Latent heats (in J/kg): fusion (3.34 x 105), vaporization (2.256 X 106) 1.0 2.0 1.5 2.5 0.5 3.0

you decided to investigate how much energy it would take to get
solid acetone to gaseous acetone. So assuming you took 125 g of
-100 degree Celsius solid acetone and heated it 56 degree Celsius
gaseous acetone, how many joules of energy would be required to do
this? Acetone has a melting point of -95 degree Celsius and a
boiling point of 56 degrees Celsius. The heat of fusion (melting)
is 98 j/g and the heat of vaporization is 538.9...

How much heat energy is required to convert 15.0 g of solid
ethanol at -114.5 °C to gasesous ethanol at 143.1 °C? The molar
heat of fusion of ethanol is 4.60 kJ/mol and its molar heat of
vaporization is 38.56 kJ/mol. Ethanol has a normal melting point of
-114.5 °C and a normal boiling point of 78.4 °C. The specific heat
capacity of liquid ethanol is 2.45 J/g·°C and that of gaseous
ethanol is 1.43 J/g·°C.

Step 2: How much energy does it take to completely vaporize the boiling water? This is where you use AH because it is a phase change. Do you use AH or AH? Vaporization means the water is vaporizing (or condensing) where fusion means the water is freezing (or melting).

An aluminum tea kettle of 0.45-kg containing 2.40-kg of water at
25°C is placed on a
burner. Assuming that the burner is rated at 2000 Watt, how long
will it take to bring
the water to a boil? (b) Once boiling begins, how much time is
required to boil all the
water out of the tea kettle? Assume that no energy is lost in this
process.
