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.
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.
An altitude gauge is an instrument that measures the vertical distance above a reference point, usually in relation to sea level. It is commonly used in aircraft to provide pilots with information about the altitude of the aircraft in flight.
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
Physical change
The weight of a piece of paper can vary depending on its size and thickness. A standard sheet of A4 paper (about 80 grams per square meter) typically weighs around 4.5 grams. Therefore, there are approximately 0.0045 kilograms in a single piece of standard A4 paper.

A standard piece of paper, such as A4 size, measures 21 centimeters in width and 29.7 centimeters in height. In the U.S., a standard letter-sized paper measures 21.6 centimeters by 27.9 centimeters. The dimensions can vary for different types of paper, but these are the most commonly used sizes.
A single sheet of A5 paper measures 21.0 centimetres long by 14.8 centimetres wide.
To convert from inches to cm, you multipy by 2.54.
A piece of paper typically measures around 0.1 millimeters thick.
A tray cover (looks like a piece of paper) or a sterilized wrapping paper used for wrapping the instrument pack.
It is a "Seismograph". It "listens" to the vibrations, and draws out (with an inked needle) the tremors onto a piece of paper. A seismometer is what measures and records earthquakes. Many modern seismometers send their data directly electronically to computers, which record and automatically analyze that data instead of using the inked needle on paper.
A single piece of A4 paper measures 297 millimetres in length and 210 millimetres in width.
An A5 piece of paper measures 148.5 mm in width and 210 mm in height. In inches, this translates to approximately 5.83 inches wide and 8.27 inches tall. A5 is part of the A series paper sizes defined by the ISO 216 standard.
A standard piece of notebook paper typically measures 8.5 inches by 11 inches. In terms of weight, a common type of notebook paper is 20 pounds (or 75 gsm), which refers to the weight of a ream (500 sheets) of paper. This makes it suitable for everyday writing and printing tasks.
On a flat plane, such as a piece of paper, it's exactly 180 degrees, regardless of the shape or size of the triangle.
