Question

An aluminum cup of mass 110 g contains 800 g of water in thermal equilibrium at 80.0°C. The combination of cup and water is cooled uniformly so that the temperature decreases by 1.50°C per minute. At what rate is energy being removed by heat? Express your answer in watts. W

Answer #1

Here,

Mass of water is,

Mw= 800 g = 0.8 kg

Then,

A 771-g aluminum pot contains 520 g of water. Their temperature
is 93.5 degree C. 260 g of water at 1.87 degree C are added to the
pot. Calculate the final temperature of the water and the aluminum
after they reach thermal equilibrium. Assume no heat is exchanged
with the surroundings. Express your answer in degree C.

An aluminum cup contains 225 g of water and a 40 g copper
stirrer, all at 27°C. A 470 g sample of silver at an initial
temperature of 89°C is placed in the water. The stirrer is used to
stir the mixture gently until it reaches its final equilibrium
temperature of 32°C. Calculate the mass of the aluminum cup.

A 100 g aluminum calorimeter contains 250 g of water. The two
substances are in thermal equilibrium at 10°C. Two metallic blocks
are placed in the water. One is a 50 g piece of copper at 82°C. The
other sample has a mass of 78 g and is originally at a temperature
of 100°C. The entire system stabilizes at a final temperature of
20°C. Determine the specific heat of the unknown second sample.

An aluminum cup contains 225 g of water and a 40-g copper
stirrer, all at 27°C. A 500-g sample of silver at an initial
temperature of 90°C is placed in the water. The stirrer is used to
stir the mixture gently until it reaches its final equilibrium
temperature of 32°C. Calculate the mass of the aluminum cup. g

An aluminum cup contains 225 g of water and a 40-g copper
stirrer, all at 27°C. A 402-g sample of silver at an initial
temperature of 86°C is placed in the water. The stirrer is used to
stir the mixture gently until it reaches its final equilibrium
temperature of 32°C. Calculate the mass of the aluminum cup.

An aluminum cup contains 225 g of water and a 40-g copper
stirrer, all at 27°C. A 480-g sample of silver at an initial
temperature of 90°C is placed in the water. The stirrer is used to
stir the mixture gently until it reaches its final equilibrium
temperature of 32°C. Calculate the mass of the aluminum cup.

A 500-g aluminum container holds 300 g of water. The water and
aluminum are initially at 40∘C. A 200-g iron block at 0∘C is added
to the water. Assume the specific heat of iron is 450 J/kg⋅∘C, the
specific heat of water 4180 J/kg⋅∘C and the specific heat of
aluminum is 900 J/kg⋅∘C

An aluminum cup contains 218 g of water at 21.5 C. A 412g sample
of silver at an initial temperature of 81.6 C is placed in the
water. A 40.2 g copper stirrer is used to stir the mixture until it
reaches its final equilibrium temperature of 27.0 C. Calculate the
mass of the aluminum cup.
I have posted this twice before and Ion capa told me there
answers of 24.29 and 30.3 were incorrect. Third times the charm

An aluminum cup contains 225 g of water and a 40-g copper
stirrer, all at 27°C. A 441-g sample of silver at an initial
temperature of 85°C is placed in the water. The stirrer is used to
stir the mixture gently until it reaches its final equilibrium
temperature of 32°C. Calculate the mass of the aluminum cup.
My answer: 163.7 g
Your response is within 10% of the correct value. This may be due
to roundoff error, or you could...

An 100-g aluminum calorimeter contains 280 g of water at an
equilibrium temperature of 20°C. A 170-g piece of metal, initially
at 277°C, is added to the calorimeter. The final temperature at
equilibrium is 32°C. Assume there is no external heat exchange. The
specific heats of aluminum and water are 910 J/kg·K and 4190
J/kg·K, respectively. The specific heat of the metal is closest
to:
a) 270 J/kg·K.
b) 240 J/kg·K.
c) 330 J/kg·K.
d) 390 J/kg·K.
e) 360 J/kg·K.
