Which statement correctly describes the relationship between the volume of a gas and its temperature, in Kelvin, assuming pressure is held constant?

(1 point)
The relationship is directly proportional; as temperature increases, volume
• increases in the same way.
The relationship is inversely proportional; as temperature increases, volume increases in the same way.
• The relationship is directly proportional; as temperature increases, volume
decreases in the same way.
• The relationship is inversely proportional; as temperature increases, volume
decreases in the same way.

The correct statement is:

The relationship is directly proportional; as temperature increases, volume increases in the same way.

This relationship is described by Charles's Law, which states that at constant pressure, the volume of a gas is directly proportional to its absolute temperature (measured in Kelvin).
