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 1.70-kg piece of aluminum that has a temperature of −147 °C is
added to 1.00 kg of water that has a temperature of 3.1 °C. At
equilibrium the temperature is 0.0°C. Assuming that the heat
exchanged with the container and the surroundings is negligible,
determine the mass of water that has been frozen into ice.

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.

An ice cube of mass 0.041 kg and temperature -13 ∘C is heated
until it is now fully melted and at a temperature of 11∘C now. What
percentage of the total energy was used to melt the ice? (Assume
that there is no heat exchange with any container or the
environment.) The specific heat of ice is 2200 J/kg ∘C and the
specific heat of water is 4186 J/kg ∘C. The latent heat of fusion
of ice is 334000 J/kg...

A 7-kg cube of copper (cCu = 386 J/kg-K) has a
temperature of 750 K. It is dropped into a bucket containing 5.5 kg
of water (cwater = 4186 J/kg-K) with an initial
temperature of 293 K.
1)
What is the final temperature of the water-and-cube system?
K
2)
If the temperature of the copper was instead 1350 K, it would
cause the water to boil. How much liquid water (latent heat of
vaporization = 2.26

A block of ice of mass 0.9 kg and initial temperature T = 0
oC is placed in a sealed insulated container full of
Helium gas, initially at temperature 220 oC and pressure
of 1 atm. The volume of the Helium is 680 L, and is
constant. Helium is a monatomic ideal gas.
What is the mass of the liquid water when the system comes to
equilibrium? (In other words, how much ice melts?)
Assume no heat is lost to...

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
exchanged with the surroundings. After thermal equilibrium is
reached, there is 0.90 kg of ice and 1.10 kg of liquid water.
Part A
What was the initial temperature of the piece of copper?
Express your answer to three significant figures...

A cubic Aluminum container (RD = 2.7) has a side length of 1 m
and thickness of 1 cm and is floating inside a water tank. The
container is empty and open from the top (i.e.: has only 4 sides
and one base). Assuming the density of water is 1000 kg/m3,
determine:
A. Height of the container floating above water. (1 mark) B.
Volume of water we can pour into the container before it sinks. I
B. f the empty...

A teaching assistant performs an experiment using an aluminum
container, with a mass of 0.150 kg, that contains 0.285 kg of
water, all initially at 26.0°C. The teaching assistant then adds a
sample of an unknown substance to the water. The sample has a mass
of 1.3 kg and an initial temperature of 90.0°C. After waiting until
the entire system reaches thermal equilibrium, the teaching
assistant measures a final temperature of 32.0°C. What is the
specific heat (in J/(kg ·...
