Which of the following is true about a 4H pencil lead?

A 4H pencil lead is classified as hard and light. The "H" scale indicates hardness, with the number preceding the "H" denoting the degree of hardness; the higher the number, the harder the lead. A 4H pencil produces a lighter mark on the paper compared to softer leads, making it suitable for fine lines, detailed work, and precise drawings.

The hardness means that it retains a fine point longer and requires less frequent sharpening, making it advantageous for tasks where detail is crucial. This is particularly useful in technical drawing and fine illustrations where precision is key. The characteristics of 4H lead make it less ideal for shading or creating bold lines, which are better suited to softer or darker pencil leads. Thus, the portrayal of a 4H pencil lead as hard and light accurately reflects its properties and intended uses.
