An ice “calorimeter” can be used to determine the specific heat capacity of a metal. A piece of hot metal is
dropped onto a weighed quantity of ice. The energy transferred from the metal to the ice can be determined
from the amount of ice melted. Suppose you heat a 9.36-g piece of platinum to 98.6 °C in a boiling water bath
and then drop it onto ice at 0.0 °C. When the temperature of the metal has dropped to 0.0 °C, it is found that
0.37 g of ice has melted. What is the specific heat capacity of platinum ? Heat of fusion of water = 333 J/g
Solutions
Expert Solution
So heat released by metal will be equal to the heat gained by ice to melt. Heat released is denoted with negative sign.
Use the formula of :
And calculate s which is specific heat capacity.
SO, s = 0.13 J/g°C

In the specific heat experiment, critical factors are the heat
capacity of the calorimeter, the temperature of the holt sample,
and the final temperature of the calorimeter. What effect could
influence the temperature of the hot sample at the instant it is
inserted into the calorimeter? What issues surround the measurement
of the final calorimeter temperature?

Question 1
A calorimeter is a device which can be used to determine the
heat of reaction. The process of measuring the heat is known as
calorimetry. Based on the above statement and from your further
findings, answer the following questions:
a) Analyze the operational principle of a calorimeter in a
proper sequence. Organize your answer in the form of a flow diagram
:
b) Outline how does the operational principle of the calorimeter
is related to the First Law...

A calorimeter that measures an exothermic heat of reaction by
the quantity of ice that can be melted is called an ice
calorimeter. Consider a reaction in which 0.00400 mol of methane
gas, CH4 (g), is burned completely at constant pressure in the
presence of excess air. The heat liberated from the reaction melted
10.7 g of ice at 0 degrees celcius (the heat required to melt the
ice (heat of fusion) is 333.5 J/g). What is the change in...

A bomb calorimeter, or constant volume calorimeter, is a device
often used to determine the heat of combustion of fuels and the
energy content of foods. Since the "bomb" itself can absorb energy,
a separate experiment is needed to determine the heat capacity of
the calorimeter. This is known as calibrating the calorimeter. In
the laboratory a student burns a 0.466-g sample of 1,8-octanediol
(C8H18O2) in a bomb calorimeter containing 1200. g of water. The
temperature increases from 25.90 °C...

The initial temperature of 140 g of ice is −22°C. The specific
heat capacity of ice is 0.5 cal/g·C° and waters is 1 cal/g·C°. The
latent heat of fusion of water is 80 cal/g.

ice after it has reached 0°C?
c. How much additional heat is required to heat the water
(obtained by melting the ice) to...

In the laboratory a student uses a "coffee cup" calorimeter to
determine the specific heat of a metal. She heats 18.3 grams of
gold to 99.38°C and then drops it into a cup containing 80.2 grams
of water at 20.87°C. She measures the final temperature to be
21.40°C. Assuming that all of the heat is transferred to the water,
she calculates the specific heat of gold to be J/g°C.
