4 pts
question 16
identify the variables of the ideal gas law.
density, velocity, molar mass, force
volume, moles, pressure, temperature
gas constant, pressure, temperature, volume
pressure, density, temperature, velocity

Explanation:

The ideal gas law is given by the formula \( PV = nRT \), where \( P \) is pressure, \( V \) is volume, \( n \) is the number of moles, \( R \) is the gas constant, and \( T \) is temperature. The variables (excluding the constant \( R \)) are volume, moles, pressure, and temperature. The first option has unrelated variables (density, velocity, force), the third includes the gas constant (not a variable), and the fourth has unrelated variables (density, velocity).

Answer:

B. Volume, moles, pressure, temperature
