Question

23 g of water at 21°C is contained in a glass container of mass 327 g. An additional 149 g of water at 100°C is added. What is the final equilibrium temperature (in degrees C) if we treat the system's water and container as isolated? Use the heat capacity values from the this table

Answer #1

183 g of water at 21°C is contained in a copper container of
mass 347 g. An additional 124 g of water at 100°C is added. What is
the final equilibrium temperature (in degrees C) if we treat the
system's water and container as isolated? Use the heat capacity
values from the this table. Specific heat capacity for copper is
387.

2.50 kg of water at 90 (degrees of C) is contained in a
thermally-isolated container. A 1.50 kg chunk of ice at - 10
degrees C is added to the water, in the same thermally isolated
container. a.) Describe the final state of the system when it has
reached thermal equilibrium, give the final temperature and the
amount of ice let (if any). b.) Find the net change in entropy of
the system during this process.

Ice of mass 52.5 g at -10.7° C is added to 220 g of water at
15.4° C in a 110 g glass container of specific heat 0.200 cal/g-°C
at an initial temperature of 25.1° C. Find the final temperature of
the system.

Ice of mass 46.5 g at -10.5° C is added to 214 g of water at
14.4° C in a 110 g glass container of specific heat 0.200 cal/g-°C
at an initial temperature of 23.7° C. Find the final temperature of
the system.

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...

In an insulated container, a 5.0 g sample of water at 80.°C was
added to an unknown mass of cooler water at 30.°C. The final
temperature of the resulting mixture became 35°C. What mass of
cooler water was present? (Assume the container itself adsorbed a
negligible amount of heat.)

Ice with a mass of 52 g originally at 0.0 deg. C is added to 450
g of water originally at 80. deg. C. Determine the final
temperature once all the ice melts and all the water reaches
thermal equilibrium. Assume that no heat is exchanged with the
container.

A perfectly insulated thermos contains 0.300 kg of water
initially at 50 degrees C. A mass os of 0.100 kg of water initially
at 10 degrees C is added. Ignore any heat exchanges with the
outside environment. Take the specific heat capacity of liquid
water as 4190 J/kgK. A) Draw a diagram for the situation,
indicating the relative masses and temperatures. B) Find the final
temperature of the combined water after they have mixed and
attained thermal equilibrium (HINT: equate...

C. 50 g of ice are poured at -6° C. Calculate the equilibrium
temperature and describe the final composition.
5. We have a puddle of hot water @ 60 ° C exposed to air @ 28

1. A piece of glass has a mass of 89 grams, an initial
temperature of 335 ºC and a specific heat of 0.9 J/g/C. It is
dipped in a water container with 225 grams of water at 19 ºC. The
water has a specific heat of 4.2 J/g/C.
What will be the final temperature in Celsius of the water and
the glass after a long time?
