Gas Law II
Performance Objectives
Students should be able to;
1. Explain using the ideas of the kinetic theory of gasses.
2. Identify and use instruments for measuring pressure.
Charles’ Law: The Temperature-Volume Law
Content
This law states that the volume of a given amount of gas held at constant pressure is directly proportional to the temperature (Kelvin).
V T
Same as before, a constant can be put in:
V / T = C (C – Constant)
As the volume goes up, the temperature also goes up, and vice-versa.
Also same as before, initial and final volumes and temperatures under constant pressure can be calculated.
V1 / T1 = V2 / T2
