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

Answer is: c.The temperature, pressure, and volume of a gas are all related.

Ideal gas law: p·V = n·R·T.

p - pressure of gas.

V -volume of gas.

n - amount of substance.

R - universal gas constant.

T - temperature of gas.

An ideal gas is:

1) made up of molecules which are in constant random motion in straight lines.  

2) all collisions are perfectly elastic, there is no loss of kinetic energy during the collision.

3) follows ideal gas law: p·V = n·R·T.

4) the gas particles have negligible volume .

Option (a) is the correct answer.

Explanation:

According to ideal gas law, product of pressure and volume is equal to product of n times R times T.

Mathematically,      PV = nRT       (1)

where      P = pressure

                V = volume

                n = number of moles

                R = gas constant

                T = temperature or absolute temperature

Therefore, we can conclude from equation (1) that product of pressure and volume of an ideal gas is proportional to the absolute temperature.
