The paper allows you to weigh the chemicals on a scale. Folding the paper also makes it easier to pour the chemicals into the test tube.
Take a piece of paper and cut it in half (anywhere will do) and you will have two pieces of paper - and your original piece of paper has changed shape.
tearing a piece of paper is a physical change because when you rip it,it is still a piece of paper but lets say that u burn a piece of paper its a chemical change couse you cant change it back to wood again

A paper scale or grammage scale is used to measure the grammage (weight) of a piece of paper. It typically measures the mass of paper in grams per square meter (g/m²) by weighing a standardized area of the paper.

Using a piece of paper helps prevent spills and ensures accurate measuring by easily guiding the solid chemicals from the weighing boat or container into the test tube. It also reduces the risk of contamination and promotes safe handling practices in the laboratory.
A clean, uncontaminated piece of paper is ideal for transferring dry chemicals to a scale for measuring weight and to a test tube where the paper can be bent or folded to act as a funnel, minimizing the possibility of spillage. The weight of the paper is minimal and if all the papers are identical, the weight can be predetermined to make weighing more accurate. Paper can be thrown away after use. The alternative is using metal or glass utensils to transport chemicals and as a funnel to fill the test tube. They all need to be washed well and dried before being used again otherwise the chemicals transferred can be contaminated by whatever was last used on the utensil.
yes everything with weight takes up space and when you write with a pencil the lead is breaking off and transferring onto a piece of paper
A pattern is composed of 2 things. The directions for assembling the item, and individual pieces that compose the item. There are 2 methods for transferring the necessary markings.
