Determine the density.
Explanation:
The best procedure a student can use to examine the intensive property of a rectangular block of wood is to determine its density.
An intensive property is a property of matter that is independent of the amount of matter present in it. Examples are density, melting point, boiling point etc.
Every substance in pure form have their distinct density. It is without regards to the mass and volume of such substance present.
Mass, length and volume are extensive properties that depends on amount of matter present.

For this problem, we use Graham's Effusion Law to find out the rate of effusion of chlorine gas. The formula is as follows:
R₁/R₂ = √(M₂/M₁)
Let 1 be N₂ while 2 be Cl₂
255/R₂ = √(28/70.8)
Solving for R₂,
R₂ = 405.5 s
<em>Thus, it would take 405.5 s to effuse chlorine gas.</em>
