Report
Gas Laws Lab Instructions: Complete all sections of this report and answer all questions in complete sentences for full credit. Title: Gas Laws Lab Objective(s): Examine the relationship between the volume and temperature of a gas using gases sealed inside syringes and then form a conclusion about the behavior of gases. Hypothesis: As the temperature increases the volume of the gases will also increase. Materials: What scientific equipment and tools were used to collect data in the simulation? (Record the materials as you work through the simulation.) Materials - 10-mL Syringes - Saltwater - Beaker - Ice - Water Variables: List variables below as you work through the simulation . Type Variable Controlled Type of Gas used Independent Temperature of Gas Dependent Volume of Gas Unless Otherwise Noted All Content © 2022 Florida Virtual School.

Procedure: Clear steps are in the simulation. No written procedure is needed for this virtual experience. However, it is important that you understand the experimental design of this lab for the conclusion section. Data: Complete the table to organize the data collected in this lab. Don't forget to record measurements with the correct number of significant figures. Water Bath Temp ( C) of the bath Trial 1: Volume (mL) Air Trial 2: Volume (mL) Pick one: H 2 / He/N 2 Ice and saltwater -14.9 4.3 4.3 Ice water 0.4 4.7 4.6 Room temp water 21.4 5.1 5.2 Warm water 48.4 5.5 5.5 Hot water 81.3 5.9 5.9 Calculations One of the gas laws equations states V 1 T 1 = V 2 T 2 . You will calculate V 2 values (theoretical) and compare them to measured values for air and your chosen gas. First, convert temperature to Kelvin. Then, write volumes of the gases from the ice and saltwater bath above. Water Bath Temp (K) T 1 Trial 1: Volume (mL) Air V 1 Trial 2: Volume (mL) H 2 /He/N 2 V 1 Ice and saltwater 258.25 4.3 4.3 What are the theoretical values of V 2 based on those initial measurements? Convert the temperatures to Kelvin for the warm and hot water baths. Then, use the gas law equation to determine what V 2 should be for each trial for the last two baths. Show your work. There should be four calculations of V 2 . Water Bath Temp (K) T 2 Trial 1: Volume (mL) Air V 2 Trial 2: Volume (mL) H 2 /He/N 2 V 2 Warm water 321.55 5.5 4.3/258.25x321.55=5.4 5.5 4.3/258.25x321.55=5.4 Hot water 354.45 5.9 4.3/258.25x354.45=5.9 5.9 4.3/258.25x354.45=5.9 Unless Otherwise Noted All Content © 2022 Florida Virtual School.
