Scenario/Summary
For this week’s lab, you will conduct the following Model ChemLab experiment: Charles’ Law.
The mathematical relationship between the temperature and volume of a gas was described by Jacques Charles in 1787. This law states that the volume of a fixed amount of a gas at a constant pressure is directly proportional to its absolute temperature. This equation is written as V = bT, where V is volume, T is temperature, and b is a proportionality constant.
Experimentally, when the same sample of trapped gas is at a constant pressure, the initial volume (V1) divided by the initial absolute temperature (V2) is equal to the final volume (V2) divided by the final absolute temperature (T2). Thus, V1/T1=V2/T2.
