Guided Inquiry Calorimetry Investigation

Pre-Lab:

Title:

Lab Partners:

Challenge: To find the change in enthalpy for...(you get to decide)

Pre Lab Questions:

1. What is Calorimetry?

2. What equation will you need to determine the change in enthalpy to address your challenge?

MSDS: Health/safety concerns and disposal information for all substances you will be using

Procedure: Detailed explanation of each step you will be following to address your challenge with labeled drawing(s) to support.

Data Table: A table set up to record 3 trials of data and put your calculated mean data.

Post Lab:

Analysis:

1. Calculate the mean/average data

2. Calculate standard deviation for your data collection.

3. Calculate enthalpy using average data.

4a. What is the theoretical value for enthalpy you experimentally determined?

b. What is your percent error for your data collect?

5. What are some factors that could have influenced your percent error?

6. Explain the energy transformations that occurred during your experiment and how the particles were affected in the system.
