Question 12 • FL-2003340-Chemistry 1 B

Which statement can best be concluded from the ideal gas law?

Answer
A
The product of pressure and volume of an ideal gas is proportional to the absolute temperature.
B
All collisions between atoms or molecules are perfectly elastic and are not the result of any attractive forces.
C
The temperature, pressure, and volume of a gas are all related.
D
The behavior of a gas under real conditions does not obey the ideal gas law.

Explanation

The ideal gas law is PV = nRT. For a fixed amount of gas, n and R are constant, so the product of pressure and volume is proportional to the absolute temperature. This matches the statement that pressure times volume varies with absolute temperature.
