What are the key properties of gases involved in the study of gas laws?

• Pressure, temperature, volume, and mass

• Density, color, taste, and smell

• Viscosity, elasticity, and rigidity

• Conductivity, magnetism, and polarity

According to Boyle's Law, what is the relationship between the volume and pressure of a gas?

• Volume is inversely proportional to temperature

• Volume is directly proportional to pressure

• Volume is inversely proportional to pressure
