Question

1. choose the best answer.

the combined gas law states that the product of the pressure and volume of a fixed quantity of gas varies ____ with its absolute temperature
○ inversely
○ directly

Explanation:

The combined gas law is expressed as $\frac{PV}{T} = k$ (where $P$ is pressure, $V$ is volume, $T$ is absolute temperature, and $k$ is a constant). Rearranging gives $PV = kT$, which shows that the product $PV$ is directly proportional to $T$.

Answer:

directly
