Calorimetry Lab Concepts and Applications

Mr. Zorn conducts a calorimetry lab to identify a metal sample by its specific heat capacity. He explains the setup, including weighing the metal, understanding the calorimeter, and heating the metal sample. The experiment involves placing the heated metal in a calorimeter to observe temperature changes, which are used to calculate the metal's specific heat capacity.

What is the main objective of the calorimetry lab experiment?

• To calculate the volume of a metal sample

• To determine the density of a metal sample

• To identify a metal sample using its specific heat capacity

• To measure the boiling point of water

What materials are used to construct the calorimeter in this experiment?

• Styrofoam cups and a glass beaker

• Plastic cups and a glass beaker

• Glass cups and a metal beaker

• Metal cups and a plastic beaker

Why is it important to ensure the metal sample is fully submerged in boiling water?

• To ensure uniform heating of the metal

• To avoid breaking the test tube

• To measure the density of the metal

• To prevent the metal from oxidizing

What should be done if the thermometer touches the bottom of the test tube?

• Adjust it to avoid contact with the bottom

• Remove the thermometer immediately

• Leave it as it is

• Replace the thermometer with a new one

What is the initial temperature of the water in the calorimeter?

• 22.4 degrees Celsius

• 25.0 degrees Celsius

• 98.9 degrees Celsius

• 20.4 degrees Celsius

What is the initial temperature of the metal sample before it is placed in the calorimeter?

• 22.4 degrees Celsius

• 98.9 degrees Celsius

• 20.4 degrees Celsius

• 25.0 degrees Celsius

What is the purpose of covering the calorimeter with aluminum foil?

• To ensure the metal does not oxidize

• To prevent water from evaporating

• To keep the metal sample in place

• To minimize heat loss to the surroundings

What is the role of the thermometer in this experiment?

• To ensure the metal is fully submerged

• To measure the density of the metal

• To stir the water in the calorimeter

• To monitor the temperature change in the calorimeter

What is the final temperature of the water after the metal sample is added to the calorimeter?

• 22.4 degrees Celsius

• 98.9 degrees Celsius

• 20.4 degrees Celsius

• 25.0 degrees Celsius

How is the specific heat capacity of the metal sample determined?

• By weighing the metal sample

• By measuring the volume of the metal

• By calculating the change in temperature of the water

• By observing the color change of the metal
