Question

Equal amounts of heat are added to equal masses of mercury and ice at the same initial temperature. Which substance will have the higher final temperature, Mercury or ice?

How much greater will that temperature change be than the temperature change of the other substance? larger ΔT/smaller ΔT =

Answer #1

If equal masses of the following substances aborb the same
amount of heat which will experience the most significant change of
temperature?
Answer choices:
SiO2(s)
NaCl(s)
H2O(l)
N2(g)
Cu(s)

Two containers, A and B, contain equal amount of the same ideal
gas occupying the same volume, and at the same temperature
initially. Container A is fitted with a moveable
piston, while volume of container B is fixed. Then
equal amount of heat is added to both systems. When heat is added
to container A, it expands. How do the final temperatures of the
two systems compare and why?
a) System A has a final higher temperature than B due...

An amount of energy is added to ice, raising its temperature
from -10°C to -5°C. A larger amount of energy is added to the same
mass of water, raising its temperature from 15°C to 20°C. From
these results, what can we conclude?
A.) Overcoming the latent heat of fusion of ice requires an
input of energy.
B.) The latent heat of fusion of ice delivers some energy to the
system.
C.) The specific heat of ice is greater than that...

An equal amount of energy is added to pieces of metal A and
metal B that have the same mass. Why does the metal with the
smaller specific heat reach the higher temperature?

⦁ Two identical containers A and B, filled with
equal masses of 2 different liquids, initially at 20°C, are heated
on a hot plate and both receive the same amount of heat. As a
result, the temperature of liquid A is raised to 40°C and that of
liquid B is raised to 80°C. If the liquids are now poured into a
third, larger container and mixed, would their final temperature be
lower, higher, or exactly equal to 60˚C? Explain your...

if a stove supplies the same amount of heat to both an iron pan
and a copper pan of equal masses, which pan will be at a higher
temperature after heating for 5 minutes?

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...

QUESTION 6 What is the relationship between the heat gained and
the heat lost by the objects? A. The heat lost is greater then the
heat gained. B. The heat gained is greater than the heat lost. C.
The heat gained is equivalent to the heat lost. D. The heat gained
and lost depend on the relative temperatures and therefore the
relationship cannot be determined with the information given.
QUESTION 7 What is the relationship between the change in
temperature...

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...

Suppose that 100.0 g of ice at 0 degrees Celsius are added to
300.0 g of water at 25.00 degrees Celsius. Is this sufficient ice
to lower the temperature of the water to 5.00 degrees Celsius and
still have ice remaining? Calculate the energy (heat), which must
be removed from water to achieve the desired temperature change,
and then prove that there is (is not) sufficient ice to cool the
water. Use the specific heat capacity of water (4.184 J/g-*C)...
