Question

Match the special cases of each gas law with its description. A law may be used more than once. In the equations, K is a constant.

A. Boyle's law
B. Charles's law
C. Avogadro's law
D. Dalton's law

____ P1 V1 = P2 V2
____ V/T = k
____ V1 / T1 = V2 / T2
____ V = kn
____ PV = k
____ Ptotal = P1 + P2 + P3 + .​

Answer 1

The special cases of the gas laws are matched with Boyle's law corresponding to P1 V1 = P2 V2, Charles's law to V/T = k or V1 / T1 = V2 / T2, Avogadro's law to V = kn, and Dalton's law to Ptotal = P1 + P2 + P3 + ...

Step-by-step explanation:

The given gas laws and their descriptions can be matched as follows:

• A. Boyle's law - P1 V1 = P2 V2
• B. Charles's law - V/T = k or V1 / T1 = V2 / T2
• C. Avogadro's law - V = kn
• D. Dalton's law - Ptotal = P1 + P2 + P3 + ...

Each law has a specific application:

• Boyle's law states that the pressure of a gas is inversely proportional to its volume when temperature and amount are held constant.
• Charles's law shows that a gas's volume is directly proportional to its temperature, holding pressure and amount constant.
• Avogadro's law suggests that the volume of a gas is directly proportional to the number of moles of gas when pressure and temperature are constant.
• Dalton's law of partial pressures states that the total pressure of a mixture of gases is the sum of the pressures of each individual gas.
