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 …
