Question

In the laboratory a student heats 93.67 grams of lead to 98.92 °C and then drops it into a cup containing 83.45 grams of water at 21.01 °C. She measures the final temperature to be 24.18 °C. calculate the calorimeter constant.

Answer #1

In the laboratory a student uses a "coffee cup" calorimeter to
determine the specific heat of a metal.
She heats 19.5 grams of tungsten
to 97.80°C and then drops it into a cup containing
78.3 grams of water at 22.58°C.
She measures the final temperature to be
23.20°C.
Assuming that all of the heat is transferred to the water, she
calculates the specific heat of tungsten to
be J/g°C.

In the laboratory a "coffee cup" calorimeter, or constant
pressure calorimeter, is frequently used to determine the specific
heat of a solid, or to measure the energy of a solution phase
reaction.
A student heats 60.93 grams of gold to 98.87 °C and then drops it
into a cup containing 79.68 grams of water at 24.46 °C. She
measures the final temperature to be 26.11 °C.
The heat capacity of the calorimeter (sometimes referred to as the
calorimeter constant) was...

In the laboratory a "coffee cup" calorimeter, or constant
pressure calorimeter, is frequently used to determine the specific
heat of a solid, or to measure the energy of a solution phase
reaction. A chunk of zinc weighing 18.01 grams and originally at
98.77 °C is dropped into an insulated cup containing 83.17 grams of
water at 20.02 °C. The heat capacity of the calorimeter (sometimes
referred to as the calorimeter constant) was determined in a
separate experiment to be 1.56...

A student drops a 0.33-kg piece of steel at 42 ∘C into a
container of water at 22 ∘C. The student also drops a 0.51-kg chunk
of lead into the same container at the same time. The temperature
of the water remains the same. What was the temperature of the
lead?

In a calorimetry experiment, a student forgot to weigh a sample
of lead that she used in the experiment. She heated the lead to
350.oC and immediately placed the heated sample into a
polystyrene calorimeter containing 475. gm H2O at
22.5oC. The final temperature was 35.7oC.
What was the mass of the lead sample?
Specific heat capacity of lead is: 0.121 J/gm/oC
Specific heat capacity of water: 4.184 J/gm/oC.

1. A chemistry student added 225 grams of aluminum at 85.00C to
115 grams of water at 23.00C in a perfect calorimeter. The final
temperature of the aluminum-water mixture was 41.40C. Use the
student’s data to calculate the specific heat of aluminum in
joules/gram0C.
