Answer #1

A 81-g ice cube at 0°C is placed in 930 g of water at 30°C. What
is the final temperature of the mixture?

A(n) 90-g ice cube at 0°C is placed in 780 g of water at 26°C.
What is the final temperature of the mixture?

A(n) 70-g ice cube at 0°C is placed in 960 g of water at 24°C.
What is the final temperature of the mixture?
______ °C

A 100g ice cube at 0°C is placed in 400g of water at 30°C. If
the container is perfectly insulated, what will be the final
temperature when all the ice has been melted? The specific heat of
water is 4.184 kJ/kg. K. The latent heat of fusion for water at 0°C
is approximately 334 kJ/kg (or 80 cal/g).

A 25 g ice cube at -15.0oC is placed in 169 g of
water at 48.0oC. Find the final temperature of the
system when equilibrium is reached. Ignore the heat capacity of the
container and assume this is in a calorimeter, i.e. the system is
thermally insulated from the surroundings. Give your answer in
oC with 3 significant figures.
Specific heat of ice: 2.090 J/g K
Specific heat of water: 4.186 J/g K
Latent heat of fusion for water: 333...

A 112-g cube of ice at 0°C is dropped into 1.0 kg of water that
was originally at 82°C. What is the final temperature of the water
after the ice has melted?
in C

A 112-g cube of ice at 0°C is dropped into 1.0 kg of water that
was originally at 84°C. What is the final temperature of the water
after the ice has melted?
_________°C

A (18) g ice cube at –15.0°C is placed in (126) g of water at
48.0 degreesC. Find the final temperature of the system when
equilibrium is reached. Ignore the heat capacity of the container
and assume this is in a calorimeter, i.e. the system is thermally
insulated from the surroundings. Give your answer in degreesC with
3 significant figures.
Specific heat of ice: 2.090 J/(g∙ oC)
Specific heat of water: 4.186 J/(g∙ oC)
Latent heat of fusion for water:...

1. A student drops an ice cube into an insulated flask full of
water and waits for the ice cube to completely melt. The ice cube
initially has a mass of 120 g and a temperature of 0°C. The water
(before the ice cube is added) has a mass of 2.00 kg and an initial
temperature of 75°C. What is the final temperature (in °C) of the
mixture? (Assume no energy is lost to the walls of the flask, or...

We drop a 22.8 g ice cube at 0∘C into 1000 g of water at 20∘C.
Find the total change of entropy of the ice and water when a common
temperature has been reached.
