Question

An ice cube of mass 0.041 kg and temperature -13 ∘C is heated until it is now fully melted and at a temperature of 11∘C now. What percentage of the total energy was used to melt the ice? (Assume that there is no heat exchange with any container or the environment.) The specific heat of ice is 2200 J/kg ∘C and the specific heat of water is 4186 J/kg ∘C. The latent heat of fusion of ice is 334000 J/kg ∘C.

I place an ice cube with a mass of 0.223 kg and a temperature of
−35°C is placed into an insulated aluminum
container with a mass of 0.553 kg containing 0.452 kg of water. The
water and the container are initially in thermal equilibrium at a
temperature of 27°C. Assuming that no heat enters
or leaves the system, what will the final temperature of the system
be when it reaches equilibrium, and how much ice will be in the
container...

Q3. A cube with side lengths of 2.91 cm is heated to a constant
temperature of 720 ◦C at the focal point inside of a parabolic
reflector. This has the effect of directing all of the cube’s
radiant energy toward a 3.92 kg pack of ice that is initially at
−19.0 ◦C. If the emissivity of the cube is 0.466, how long does it
take for the ice to completely vaporize? Use the following numbers
in your calculation:
• The...

You decide to put a 40.0 g ice cube at -10.0°C into a well
insulated coffee cup (of negligible heat capacity)
containing of water at 5.0°C. When equilibrium is
reached, how much of the ice will have melted? The specific heat of
ice is 2090 J/kg ∙ K, that of water is 4186 J/kg ∙ K, and the
latent heat of fusion of water is 33.5 × 104 J/kg.

How much energy is required to change a 23 g ice cube from ice
at − 12 ◦ C to steam at 101 ◦ C? The specific heat of ice is 2090 J
/ kg · ◦ C and of water 4186 J / kg · ◦ C. The latent heat of
fusion of water is 3 . 33 × 10^5 J / kg, its latent heat of
vaporization is 2 . 26 × 10^6 J / kg, and the...

A 100g ice cube at 0°C is placed in 400g of water at 30°C. If
the container is perfectly insulated, what will be the final
temperature when all the ice has been melted? The specific heat of
water is 4.184 kJ/kg. K. The latent heat of fusion for water at 0°C
is approximately 334 kJ/kg (or 80 cal/g).

A 0.0700 kg ice cube at −30.0°C is placed in 0.517 kg of 35.0°C
water in a very well insulated container. What is the final
temperature? in celsius ? The latent heat of fusion of water is
79.8 kcal/kg, the specific heat of ice is 0.50 kcal/(kg · °C), and
the specific heat of water is 1.00 kcal/(kg · °C).

Hot tea (water) of mass 0.21 kg and temperature 62 ∘C is
contained in a glass of mass 200 g that is initially at the same
temperature. You cool the tea by dropping in ice cubes out of the
freezer that are at a temperature of – 11 ∘C. What is the minimum
amount of ice in you need to make ice tea (final temperature of
0∘C)? Give your answer in kg to two decimal places. The specific
heat of...

An open container holds ice of mass 0.530 kg at a temperature of
-17.7 ∘C . The mass of the container can be ignored. Heat is
supplied to the container at the constant rate of 770 J/minute .
The specific heat of ice to is 2100 J/kg⋅K and the heat of fusion
for ice is 334×103J/kg.
How much time tmelts passes before the ice
starts to melt?
From the time when the heating begins, how much time
trise does it...

A cube of ice is taken from the freezer at -6.5 ?C and placed in
a 85-g aluminum calorimeter filled with 300 g of water at room
temperature of 20.0 ?C. The final situation is observed to be all
water at 17.0 ?C. The specific heat of ice is 2100 J/kg?C?, the
specific heat of aluminum is 900 J/kg?C?, the specific heat of
water is is 4186 J/kg?C?, the heat of fusion of water is 333 kJ/Kg.
