Question

A piece of unknown material of mass 0.15 kg is heated to 110°C without melting and then placed in a calorimeter containing 0.76 kg of water initially at 14.5°C. The system reaches an equilibrium temperature of 20.8°C

a) What is the specific heat of the unknown material,
in units of J/(kg⋅°C)? The specific heat of water is 4.186 ×
10^{3} J/(kg⋅°C).

Answer #1

An unknown material has a normal melting/freezing point of -29.1
°C, and the liquid phase has a specific heat capacity of 178 J/(kg
C°). One-tenth of a kilogram of the solid at -29.1 °C is put into a
0.132-kg aluminum calorimeter cup that contains 0.165 kg of
glycerin. The temperature of the cup and the glycerin is initially
26.9 °C. All the unknown material melts, and the final temperature
at equilibrium is 18.0 °C. The calorimeter neither loses energy to...

An unknown metal of mass 0.280 kg is heated to 160.0°C and
dropped in an aluminum calorimeter of mass 0.250 kg that contains
0.170 kg of water at 30°C. The calorimeter, water, and unknown
metal have a final temperature of 46.0°C. Find the specific heat of
the unknown metal. Hint: you need the specific heat of water and
aluminum. Use units of [J/(kg.K)] and the values in your book for
the specific heat.

A piece of titanium metal with a mass of 20.8 g is heated in
boiling water to 99.5 0C and then dropped into a coffee
cup calorimeter containing 75.0 g of water at 21.7
0C.When thermal equilibum is reached, the final
temperature is 14.30C.Calculate the specific heat
capacity of titanium. ( Specific Heat Capacity of H2O
(l) =4.184 J g-1 0C-1)

An unknown substance has a mass of 0.125 kg and an initial
temperature of 79.8°C. The substance is then dropped into a
calorimeter made of aluminum containing 0.285 kg of water initially
at 21.0°C. The mass of the aluminum container is 0.150 kg, and the
temperature of the calorimeter increases to a final equilibrium
temperature of 32.0°C. Assuming no thermal energy is transferred to
the environment, calculate the specific heat of the unknown
substance.

An unknown substance has a mass of 0.125 kg and an initial
temperature of 92.5°C. The substance is then dropped into a
calorimeter made of aluminum containing 0.285 kg of water initially
at 27.0°C. The mass of the aluminum container is 0.150 kg, and the
temperature of the calorimeter increases to a final equilibrium
temperature of 32.0°C. Assuming no thermal energy is transferred to
the environment, calculate the specific heat of the unknown
substance.

A 0.0456 kg ingot of metal is heated to 215◦C and then is
dropped into a beaker containing 0.415 kg of water initially at
19◦C. If the final equilibrium state of the mixed system is 21.4
◦C, find the specific heat of the metal. The specific heat of water
is 4186 J/kg · ◦ C.
Answer in units of J/kg · ◦ C.

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 25.0g piece of aluminum (molar heat capacity of 24.03 J/g
degrees Celsius) is heated to 82.4 degrees Celsius and dropped into
a calorimeter containing water (specific heat capacity of water is
4.18 J/g degrees Celsius) initially at 22.3 degrees Celsius. The
final temperature of the water is 24.98 degrees Celsius. Calculate
the mass of water in the calorimeter.

A mass of 43.0 g of an unknown solid initially at 130.0 ∘C is
added to an ideal constant pressure calorimeter containing 100.0 g
of water (Cs,water=4.184J/(g⋅∘C)) initially at 20.0 ∘C.
After the mixture reaches thermal equilibrium, the final
temperature is recorded to be 36.49 ∘C. What is the specific heat
capacity of the unknown solid?
Express your answer to three significant figures.

unknown object has a mass of 20kg and a specific heat of 5
kg-1 K-1. The object is heated to 350K and then placed in a bucket
containing 50L of water initially at 300K. If the bucket is a
perfect insulator, with negligible heat capacity, what is the final
temperature of the water after thermal equilibrium has been
established?
