Answer #1

A 24 g block of ice is cooled to −63◦C. It is added
to 572 g of water in a 98 g copper calorimeter at a temperature of
30◦C.
Find the final temperature. The specific heat of copper is 387
J/kg ·◦C and of ice is 2090 J/kg ·◦C. The
latent heat of fusion of water is 3.33 × 105 J/kg and its specific
heat is 4186 J/kg·◦C.
Answer in units of ◦C.

g of water in an 80 g copper calorimeter at a temperature of 27°C.
Determine the final temperature of the system consisting of the
ice, water, and calorimeter. Remember that the ice must first warm
to 0°C, melt, and then continue warming as water. The specific heat
of ice is 0.500 cal/g ·°C = 2090 J/kg°C.

A 40-g block of ice is cooled to −76°C and is then added to 570
g of water in an 80-g copper calorimeter at a temperature of 26°C.
Determine the final temperature of the system consisting of the
ice, water, and calorimeter. (If not all the ice melts, determine
how much ice is left.) Remember that the ice must first warm to
0°C, melt, and then continue warming as water. (The specific heat
of ice is 0.500 cal/g · °C...

A 40-g block of ice is cooled to
−72°C
and is then added to 590 g of water in an 80-g copper
calorimeter at a temperature of 26°C. Determine the final
temperature of the system consisting of the ice, water, and
calorimeter. (If not all the ice melts, determine how much ice is
left.) Remember that the ice must first warm to 0°C, melt, and then
continue warming as water. (The specific heat of ice is 0.500 cal/g
· °C...

A 40-g block of ice is cooled to −70°C and is then added to 570
g of water in an 80-g copper calorimeter at a temperature of 22°C.
Determine the final temperature of the system consisting of the
ice, water, and calorimeter. (If not all the ice melts, determine
how much ice is left.) Remember that the ice must first warm to
0°C, melt, and then continue warming as water. (The specific heat
of ice is 0.500 cal/g · °C...

A 2.5 kg metallic block with an initial temperature of 80°C is
placed in a styrofoam cup containing 0.1 kg of ice at -15°C.

◦ C, the specific heat of water is 4186 J/kg · ◦ C, the specific
heat of stream is 2010 J/kg · ◦ C, the heat of fusion is 3.33 × 105
J/kg, and the heat of vaporization is 2.26 × 106 J/kg. Answer in
units of J

How much energy is required to change a 23 g ice cube from ice
at − 12 ◦ C to steam at 101 ◦ C? The specific heat of ice is 2090 J
/ kg · ◦ C and of water 4186 J / kg · ◦ C. The latent heat of
fusion of water is 3 . 33 × 10^5 J / kg, its latent heat of
vaporization is 2 . 26 × 10^6 J / kg, and the...

An insulating cup contains water at 25 ∘C. 30 grams of ice at 0
∘C is placed in the water. The system comes to equilibrium with a
final temperature of 14∘C. How much water in grams was in the cup
before the ice was added? (specific heat of ice is 2090 J/(kg
LaTeX: ^\circ∘C), specific heat of water is 4186 J/(kg LaTeX:
^\circ∘C), latent heat of the ice to water transition is 3.33 x10^5
J/kg)
