Which three variables are commonly involved in the study of gas laws in chemistry?

• A. Pressure, concentration, and mass
• B. Volume, density, and concentration
• C. Pressure, volume, and temperature
• D. Mass, density, and temperature

Answer: (C)

Verified step by step guidance

1. Identify the key variables that describe the behavior of gases in chemistry. Gas laws typically relate how gases respond to changes in their environment.
2. Recall that the fundamental gas laws (such as Boyle's Law, Charles's Law, and Gay-Lussac's Law) involve the relationship between pressure, volume, and temperature of a gas.
3. Understand that pressure (\(P\)) is the force exerted by gas particles on the walls of their container, volume (\(V\)) is the space the gas occupies, and temperature (\(T\)) reflects the average kinetic energy of the gas particles.
4. Note that concentration and mass are not primary variables in the basic gas laws, although they can be relevant in other contexts.
5. Conclude that the three variables commonly involved in the study of gas laws are pressure, volume, and temperature.
