which of the following pencils will create a lightest mark?
2h
5h
5b
7b
The 2H pencil will create the lightest mark.
The pencil that creates the lightest mark would be 2H. The "H" in the grading system for pencils stands for "hardness" and the higher the number, the harder the lead is, resulting in lighter marks. So, 2H would create a lighter mark compared to 5H, 5B, and 7B.
To determine which pencil will create the lightest mark, you need to understand the grading system used for pencils. The grading system is based on a combination of letters and numbers. The letter "H" represents the hardness of the pencil, while the letter "B" represents the softness or darkness of the pencil.
In this case, we are comparing the pencils 2H, 5H, 5B, and 7B.
The "H" pencils are considered hard pencils and produce lighter marks. The higher the number before the "H," the lighter the mark. So, a 2H pencil will create a lighter mark compared to a 5H pencil.
On the other hand, the "B" pencils are considered soft pencils and produce darker marks. The higher the number after the "B," the darker the mark. So, a 5B pencil will create a lighter mark compared to a 7B pencil.
Based on this information, we can conclude that the 2H pencil will create the lightest mark out of the options provided.
