Question
Water is added initially to help mix the graphite and clay.Determine why the water then has to be removed by drying.It makes the leads:too brittletoo softtoo thick
Solution
The water is removed by drying because if it is not, it can make the pencil leads too soft. When the water is present, it acts as a binder for the graphite and clay, allowing them to mix together. However, if the water remains in the lead, it can weaken the structure of the lead, making it too soft and prone to breaking. Therefore, the water needs to be removed by drying to ensure the leads are strong and durable.
