The correct relationships between volume, pressure, and temperature of an enclosed gas are described by the ideal gas law and foundational gas laws. The correct relationships are:
- Volume and temperature: directly proportional (as temperature increases, volume increases when pressure is constant).
- Pressure and volume: inversely proportional (as volume increases, pressure decreases when temperature is constant).
- Pressure and temperature: directly proportional (as temperature increases, pressure increases when volume is constant).
Based on these principles, the correct response is:
Quantities Relationship
- Volume and temperature: directly proportional
- Pressure and volume: inversely proportional
- Pressure and temperature: directly proportional
So the first option is the correct one.
