Question

7. Calorimetry A piece of metal has mass 100 grams and an initial temperature of 100'C. lt is placed in an insulated container of mass 200 grams which contains 500 grams of water at an initial temperature of 17 .3"C. The container is made of the same material as the metal sample. lf the final temperature is 22.7'C, what is the specific heat capacity of this metal? How many calories ('1 cal = 4.186 J) are required to warm the metal sample by 10 degrees C?

Answer #1

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?

A 5.10 kg piece of solid copper metal at an initial temperature
T is placed with 2.00 kg of ice that is initially at -25.0 ∘C. The
ice is in an insulated container of negligible mass and no heat is

A student places a 72.0 gram sample of metal at an initial
temperature of 100.˚C in a coffee cup calorimeter that contains
40.0 grams of water at an initial temperature of 25.0 ˚C. After
addition of the metal, the temperature of the water / metal mixture
was monitored using a temperature probe. The highest temperature of
the water / solid combination was found to be 35.0 ˚C. (The
specific heat of water = 4.18 J / g ˚C )

Calculate the specific heat of a metal (in calories/gram-degree
C) from the following data. A container made of the metal has a
mass of 3.80 kg and contains 13.1 kg of water. A 1.40 kg piece of
the same metal, initially at a temperature of 140 degrees C, is
placed in the water. The container and water initially have a
temperature of 15 degrees C, and the final temperature of the
entire system is 18 degrees C.

Calculate the specific heat of a metal (in calories/gram-degree
C) from the following data. A container made of the metal has a
