Question

the combined gas law (pages 80 - 81)

1. circle the letters of the factors that are included in the expression of the combined gas law.

a. temperature
b. number of particles
c. volume
d. pressure

Explanation:

The combined gas law is expressed as $\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$, where $P$ represents pressure, $V$ represents volume, and $T$ represents temperature. The number of particles is not part of the combined gas law (it is part of the ideal gas law $PV = nRT$ where $n$ is the number of moles/particles).

Answer:

a. temperature, c. volume, d. pressure
