Question

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 ice is 2200 J/kg ∘C, the specific heat of glass is 840 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.

Answer #1

Tina is going to make iced tea by first brewing hot tea, then
adding ice until the tea cools. Ice, at a temperature of −10.0°C,
should be added to a 3.70 × 10−4 m3 glass of
tea at 95.0°C to cool the tea to 10.0°C. The glass has a mass of
0.350 kg and the specific heat of the glass is 0.837 kJ/(kg·K).
Specific heat capacity (15.0°C) of water is 4.186 kJ/(kg·K) and
heat of fusion of water is 333.7...

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...

Question:
After a long day of food, football and family, you decided to
relax with a nice glass of wine. Of course, you have to have it
just perfect in order to fully enjoy it, so you want your beverage
to have a final temperature of 10 degree Celcius. You fill your
favorite glass cup (mass of 279g and C of glass = 840 J/kgC)
initially at 22 degree Celcius with 480g of your favorite wine
innitially at 15 degree...

A 0.033 kg glass (with c = 840 J/kg oC) contains 0.281 of
lemonade which, due to the sugar content, has a specific heat of
4,208 J/kg oC. After putting 0.049 kg of ice into the glass and
allowing it to completely melt the final equilibrium temperature of
the glass of lemonade is found to be 2.9 oC. intial temperature is
0.
(a) Calculate the initial temperature of the lemonade and glass.
oC
Note the following data for ice/water: specific...

A person makes a quantity of iced tea by mixing 500 g of hot tea
(essentially water) with an equal mass of ice at its melting point.
If the initial hot tea is at a temperature of (a) 96 C and (b) 66
C, what is the temperature and mass of the remaining ice when the
tea and ice reach the same temperature? (Specific heat of water =
4.19 J/g-deg, latent heat of fusion of ice = 333 J/g.)

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...

A jar of tea is placed in sunlight until it reaches an
equilibrium temperature of 31.2◦C. In an attempt to cool the
liquid, which has a mass of 196 g, 131 g of ice at 0.0◦C is added.
At the time at which the temperature of the tea is 26.5◦ C , find
the mass of the remaining ice in the jar. The specific heat of
water is 4186 J/kg ·◦ C . Assume the specific heat capacity of the...

Chapter 18, Problem 041
(a) Two 58 g ice cubes are dropped into 410 g
of water in a thermally insulated container. If the water is
initially at 20°C, and the ice comes directly from a freezer at
-11°C, what is the final temperature at thermal equilibrium?
(b) What is the final temperature if only one ice
cube is used? The specific heat of water is 4186 J/kg·K. The
specific heat of ice is 2220 J/kg·K. The latent heat of...

A jar of tea is placed in sunlight until it reaches an
equilibrium temperature of 30.7 ◦C . In an attempt to cool the
liquid, which has a mass of 170 g , 118 g of ice at 0.0 ◦C is
added. At the time at which the temperature of the tea is 28.6 ◦C ,
find the mass of the remaining ice in the jar. The specific heat of
water is 4186 J/kg · ◦ C . Assume the...

A copper cylinder with a mass of 125 g and temperature of 345°C
is cooled by dropping it into a glass beaker containing 565 g of
water initially at 20.0°C. The mass of the beaker is 50.0 g and the
specific heat of the glass is 840 J/kg∙K. What is the final
equilibrium temperature of the system, assuming the cooling takes
place very quickly, so that no energy is lost to the air? The
specific heat of copper is 385...
