Question

8.00 g of aluminum at 200∘C and 19.0 g of copper are dropped into 44.0 cm3 of ethyl alcohol at 15.0∘C The temperature quickly comes to 27.0 ∘C. What was the initial temperature of the copper?

Answer #1

8.00 g of aluminum at 200∘C and 19.0 g of copper are dropped
into 50.0 cm3 of ethyl alcohol at 15.0∘C. The temperature quickly
comes to 25.0 ∘C.
What was the initial temperature of the copper in ∘C?

A 200 g of copper, initially at 300o C, is dropped into a 350 g
of water contained in a 355 g aluminum calorimeter; the water and
the calorimeter are initially 15o C. If 25 g iron stirrer is used
to bring the mixture into thermal equilibrium, what is the final
temperature of the system? ( Assume that the stirrer is initially
at 15o C.) Specific heat of copper and aluminum are 0.092 cal/g oC
and 0.215 cal/g oC respectively....

A 200 g block of copper at a temperature of 75°C is dropped into
650 g of water at 35°C. The water is contained in a 400 g glass
container. What is the final temperature of the mixture?

26.0 g of copper pellets are removed from a 300∘C oven and
immediately dropped into 90.0 mL of water at 19.0 ∘C in an
insulated cup. What will the new water temperature be?

A 180 g copper bowl contains 150 g of water, both at 19.0°C. A
very hot 490 g copper cylinder is dropped into the water, causing
the water to boil, with 10.5 g being converted to steam. The final
temperature of the system is 100°C. Neglect energy transfers with
the environment. (a) How much energy is transferred to the water as
heat? (b) How much to the bowl? (c) What is the original
temperature of the cylinder? The specific heat...

8. A 180 g block of copper heated to 120 degrees Celsius dropped
into a 360 g aluminum calorimeter container
containing 440 g of water. If the initial temperature of the
calorimeter and the water is 20 °C,
what is the final equilibrium temperature of the system?
9. 25 g steam at 110 °C is added temperature of the resulting
water 100 g of ice at -10 °C in an
insulated container. What is the final temperature of the resulting...

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.

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.
