Which statement correctly describes the relationship between the volume of a gas and its temperature, in Kelvin, assuming pressure is held constant?
1. The relationship is inversely proportional; as temperature increases, volume increases in the same way.
2. The relationship is inversely proportional; as temperature increases, volume decreases in the same way.
3. The relationship is directly proportional; as temperature increases, volume decreases in the same way.
4. The relationship is directly proportional; as temperature increases, volume increases in the same way.
4. The relationship is directly proportional; as temperature increases, volume increases in the same way.
The correct statement is:
4. The relationship is directly proportional; as temperature increases, volume increases in the same way.
To determine the correct relationship between the volume of a gas and its temperature, we need to refer to the gas laws, specifically Charles's Law.
Charles's Law states that, at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin. This means that as the temperature increases, the volume of the gas also increases, and as the temperature decreases, the volume of the gas decreases.
Therefore, the correct statement describing the relationship between the volume of a gas and its temperature, assuming pressure is held constant, is:
4. The relationship is directly proportional; as temperature increases, volume increases in the same way.
