Question

1. what does a graph representing charless law show?

volume increases at the same rate as pressure.
volume decreases as temperature increases.
volume increases at the same rate as temperature.
volume decreases as pressure increases.

Explanation:

Charles's law states that, at constant pressure, the volume of a gas is directly proportional to its temperature (in Kelvin). So, when temperature increases, volume increases proportionally.

Answer:

Volume increases at the same rate as temperature.
