Question

Show all your work. Make sure every number has a unit and you show the equations in the variable form before plugging in values.

Lava is around 1200 C. If you have 1000 kg of lava, which has a specific heat of lava is 0.84x103 J/(kg C). How many 1 kg bags of ice cubes, with a specific heat of 4186 J/(kg C) at 0 C, will it take to raise the lava temperature to 22 C? The latent heat of fusion for 334x103 J/kg. Assume the amount of melted ice equals that of ice in your calculation.

You decide to put a 40.0 g ice cube at -10.0°C into a well
insulated coffee cup (of negligible heat capacity)
containing of water at 5.0°C. When equilibrium is
reached, how much of the ice will have melted? The specific heat of
ice is 2090 J/kg ∙ K, that of water is 4186 J/kg ∙ K, and the
latent heat of fusion of water is 33.5 × 104 J/kg.

A copper block with a mass of 400 grams is cooled to 77 K by
being immersed in liquid nitrogen. The block is then placed in a
Styrofoam cup containing some water that is initially at +50.0°C.
Assume no heat is transferred to the cup or the surroundings. The
specific heat of liquid water is 4186 J/(kg °C), of solid water is
2060 J/(kg °C), and of copper is 385 J/(kg °C). The latent...

8.33 kg of steam at temperature of 150 ∘C has 2.23×107 J of heat
removed from it. Determine the final temperature and phase of the
result once the heat has been removed if the heat is removed at
constant pressure during the gas phase.
For this problem, use the specific heat (at constant pressure)
for water as 1850 J/kg∘C , the latent heat of vaporization as
2.256×106 J/kg , the specific heat of liquid water as 4186 J/kg∘C ,

The water in your home has been temporarily shut off.
You want to boil some water for tea but all you have is a block of
ice (200 g) in your freezer. You put the ice in a pot and heat it
up. It takes 4 minutes to take the ice from (-10 degrees celsius)
to (100 degrees celsius). After 8 minutes how much water is left in
the pot?
The specific heat of ice is 2100 J/kg*C, the specific...

Question:
After a long day of food, football and family, you decided to
relax with a nice glass of wine. Of course, you have to have it
just perfect in order to fully enjoy it, so you want your beverage
to have a final temperature of 10 degree Celcius. You fill your
favorite glass cup (mass of 279g and C of glass = 840 J/kgC)
initially at 22 degree Celcius with 480g of your favorite wine
innitially at 15 degree...

Q3. A cube with side lengths of 2.91 cm is heated to a constant
temperature of 720 ◦C at the focal point inside of a parabolic
reflector. This has the effect of directing all of the cube’s
radiant energy toward a 3.92 kg pack of ice that is initially at
−19.0 ◦C. If the emissivity of the cube is 0.466, how long does it
take for the ice to completely vaporize? Use the following numbers
in your calculation:
• The...

A perfectly insulated, sealed chamber has a fixed volume of 24.2

A sphere of iron is heated up to 1000° C. Once heated, it has a
radius of 1 cm.
Now suppose that we take the same 1000° C iron sphere and plunge
it into a thermally insulated container with 1kg of 0° C ice.
Calculate the temperature of the contents of the container once
they have come to thermal equilibrium.
Additional information: • The density of iron is 7.874 g/cm3.
Assume that this density does not depend on temperature. •...

As an eager scientist on a hot summer day you wish to determine
how much ice to buy to add to your cooler which is filled with 32
cans of soda which are warm at 82.9°F. Each can has a mass of 402 g
and ideally you want the temperature of the drinks to be 40.1°F. If
there is no heat lost by the cooler and ignoring any heat lost to
the soda containers, how much ice needs to be...
